NAS Backup Software Guide Australia 2026 — Hyper Backup, HBS, Veeam and More

Every NAS vendor ships free backup software with their hardware, but the quality, flexibility, and cloud integration vary enormously between brands. Synology's Hyper Backup and Active Backup suite are widely regarded as the best in the consumer and SMB space. QNAP's HBS 3 (Hybrid Backup Sync) is a capable alternative. Third-party tools like Veeam, Acronis Cyber Protect, Duplicati, and rclone fill gaps for cross-platform environments and enterprise requirements. This guide breaks down what each tool does, which NAS brands it works with, what it costs (if anything), and how Australian NBN realities affect your offsite backup strategy.

For a broader overview of this topic, see our complete home backup guide.

Why NAS Backup Software Matters

A NAS without a backup strategy is a single point of failure. RAID protects against drive failure, but it does not protect against ransomware, accidental deletion, fire, flood, or theft. The 3-2-1 backup strategy (three copies, two media types, one offsite) remains the gold standard, and backup software is what makes it work without manual effort. The right software automates the process: pulling data from your devices to the NAS, then pushing a copy from the NAS to the cloud or an external drive.

Choosing backup software is not just about features on a comparison chart. It is about which tool integrates cleanly with your NAS brand, your operating systems, your cloud provider of choice, and your Australian internet connection. A tool that works brilliantly on a 500 Mbps symmetric US fibre connection may be completely impractical on a typical Australian NBN 100 plan with 20 Mbps upload (or 40 Mbps on NBN 100/40). Getting this decision right upfront saves hours of frustration later.

Built-In NAS Backup Software. Brand by Brand

Synology: Hyper Backup and Active Backup Suite

Synology's backup ecosystem is the most complete in the consumer/SMB NAS space, and it is entirely free with every Synology NAS. There are two core tools with distinct purposes:

Hyper Backup handles NAS-to-destination backup. It takes data that is already on your Synology NAS and sends it somewhere else. Destinations include USB drives connected to the NAS, remote Synology NAS units, rsync-compatible servers, and cloud services including Synology C2 Storage, Backblaze B2, Amazon S3, Azure Blob, Google Cloud Storage, and more. Hyper Backup supports versioning (keep multiple historical snapshots of your files), client-side encryption (data is encrypted before it leaves your NAS), block-level deduplication (only changed portions of files are uploaded after the first backup), and flexible scheduling. For most Australians implementing 3-2-1 backup, Hyper Backup is the tool that handles your offsite copy.

Active Backup for Business pulls backups from other devices to your Synology NAS. It supports full-image backup of Windows PCs and servers, file-level backup of Linux servers, VMware and Hyper-V virtual machine backup, Microsoft 365 and Google Workspace cloud account backup, and rsync tasks from other NAS devices. It is agent-based for physical machines (install a small client on each PC or server) and agentless for virtual machines. The deduplication engine is genuinely impressive. Backing up 10 Windows PCs that share the same base OS image consumes far less space than 10 individual full backups. For a small business running 5-15 machines, Active Backup for Business replaces a paid backup product like Veeam or Acronis at no additional cost.

Synology Drive is worth mentioning alongside the backup tools. It provides Dropbox-style file sync and selective sync between your computers and the NAS. While it is primarily a sync tool rather than a backup tool (synced deletions propagate), it does include versioning that can act as a safety net. Many home users pair Synology Drive for day-to-day file access with Hyper Backup for offsite protection. See our Synology setup guide for detailed configuration steps.

QNAP: HBS 3 (Hybrid Backup Sync)

QNAP's HBS 3 (Hybrid Backup Sync) combines backup, restore, and synchronisation into a single application. It handles both NAS-to-cloud backup (equivalent to Hyper Backup) and device-to-NAS sync (partial equivalent to Synology Drive). HBS 3 supports backup to local folders, external USB drives, remote QNAP NAS units, RTRR (Real-Time Remote Replication), rsync servers, and cloud services including Amazon S3, Azure, Google Cloud, Backblaze B2, Wasabi, and QNAP's own myQNAPcloud Storage.

HBS 3 supports QuDedup (QNAP's deduplication technology) which reduces upload size by deduplicating data at the source before transmission. This is particularly valuable for Australian users on NBN connections where upload bandwidth is precious. Encryption, compression, versioning, and scheduling are all supported. The interface is functional but less polished than Synology's. QNAP has historically prioritised feature breadth over UI refinement.

For pulling backups from PCs and servers, QNAP offers QNAP NetBak PC Agent. A Windows agent that performs full-image or file-level backup to a QNAP NAS, similar to Synology's Active Backup for Business. It is a more recent product and not yet as mature as Synology's offering, but it is functional and free. QNAP also offers Boxafe for Microsoft 365 and Google Workspace backup, though it requires a licence for more than 5 accounts.

Asustor: DataGuard and Backup Plan

Asustor includes two backup tools with ADM (Asustor Data Master): DataGuard for NAS-to-external and NAS-to-NAS backup, and Backup Plan for cloud backup. DataGuard handles local USB backup, remote Asustor NAS backup via rsync, and basic scheduled backup tasks. Backup Plan supports backup to Amazon S3, Azure, Backblaze B2, Google Cloud, Wasabi, and other S3-compatible targets.

The honest assessment: Asustor's backup tools are functional but significantly less polished and feature-rich than Synology or QNAP's offerings. There is no equivalent to Active Backup for Business for pulling PC/server backups to the NAS, no built-in Microsoft 365 backup, and the deduplication capabilities are basic. If backup is a primary use case for your NAS, this is a genuine weakness of the Asustor platform. For offsite cloud backup, Asustor's tools get the job done, but you may find yourself reaching for third-party tools like Duplicati or rclone for more complex backup workflows.

Comparison: Built-In NAS Backup Tools

Third-Party Backup Software for NAS

Built-in NAS backup tools handle most scenarios well, but there are legitimate reasons to look at third-party software: you have a mixed-brand NAS environment, you need enterprise features like centralised management, your NAS vendor's tools do not support your specific cloud provider, or you want vendor-neutral backup that survives a NAS brand switch. Here are the options worth considering in Australia in 2026.

Veeam Backup and Replication (Community Edition)

Veeam is the dominant backup platform in enterprise IT, and the Community Edition is free for up to 10 workloads (any combination of VMs, physical servers, workstations, or NAS shares). For a small business with a few servers, a handful of PCs, and a NAS, Veeam Community Edition covers the lot without licence costs. Veeam backs up to a NAS share (SMB or NFS) as a repository target, meaning any NAS brand works. Synology, QNAP, Asustor, UGREEN, TerraMaster, or even a Linux server with Samba.

Veeam runs on a Windows machine (physical or VM) as a backup server, not on the NAS itself. It pulls backup data from your protected machines and writes it to your NAS. From there, you can configure Veeam to copy backups offsite to cloud storage (Backblaze B2, AWS S3, Azure, Wasabi) using Veeam's Scale-out Backup Repository with a capacity tier. For small businesses already running a Windows server, adding Veeam Community Edition is one of the smartest infrastructure decisions you can make. Enterprise-grade backup for free.

The paid version (Veeam Backup and Replication) starts at approximately $700-800 AUD per socket for VMware/Hyper-V environments. For most Australian SMBs with fewer than 10 workloads, the free Community Edition is sufficient.

Acronis Cyber Protect (Home and Business)

Acronis Cyber Protect (formerly Acronis True Image for home users) combines backup with anti-malware and ransomware protection. The home edition costs approximately $90-150 AUD/year depending on the plan, with cloud storage included (250GB to 5TB depending on tier). The business edition is priced per-workload with centralised management.

Acronis can back up PCs and servers to a NAS share (any brand) and to Acronis Cloud (data centre in Sydney, which is relevant for Australian latency and data sovereignty). The integration with NAS is straightforward. Point Acronis at a network share on your NAS and it writes backup archives there. It does not run on the NAS itself. The combined backup-plus-security approach appeals to users who want a single vendor for both, though the backup-only functionality is not as deep as Veeam's. Acronis suits home users and very small businesses who want a simple, all-in-one protection tool and are willing to pay the annual subscription.

Duplicati (Free, Open Source)

Duplicati is a free, open-source backup tool that runs on Windows, macOS, and Linux. Including directly on some NAS devices via Docker. It backs up to over 20 cloud storage destinations including Backblaze B2, Amazon S3, Google Drive, OneDrive, Azure, Wasabi, and any S3-compatible or WebDAV target. Duplicati supports client-side AES-256 encryption, incremental backup with deduplication, scheduling, and email notifications.

For technically capable users, Duplicati running in a Docker container on a NAS is one of the most flexible and cost-effective backup solutions available. It is entirely vendor-neutral. It works identically on Synology, QNAP, Asustor, or any NAS that supports Docker. The web-based interface runs on port 8200 and is accessible from any browser. The tradeoff: Duplicati requires more initial setup than vendor-provided tools, the UI is utilitarian rather than polished, and community support replaces commercial support. If you are comfortable with Docker and basic networking, Duplicati is outstanding. If you want a guided setup wizard, stick with your NAS vendor's built-in tools.

rclone (Free, Open Source, Command-Line)

rclone is a command-line tool that syncs files between your NAS and over 70 cloud storage providers. Think of it as rsync for cloud storage. It runs natively on Linux (and therefore on most NAS devices directly or via Docker), supports encryption, bandwidth limiting (essential for Australian NBN connections), and can be automated via cron jobs or scheduled tasks.

rclone is not a traditional backup tool. It does not natively handle versioning, deduplication, or incremental block-level backup. It is a sync and transfer tool. However, paired with cloud storage that supports versioning (Backblaze B2 has free file versioning), rclone becomes a powerful offsite backup engine. Many advanced NAS users run rclone via Docker or SSH on their Synology or QNAP NAS with a nightly cron job syncing critical folders to Backblaze B2. Bandwidth limiting is configured with the --bwlimit flag. Set it to 80% of your NBN upload speed to avoid saturating your connection during backup windows.

rclone suits technically confident users who want full control over their backup process and are comfortable with the command line. For everyone else, Duplicati provides similar flexibility with a web-based GUI.

Cloud Storage Options and AU Pricing

Offsite backup to cloud storage is the most practical way to satisfy the "1 offsite" requirement of 3-2-1 backup for most Australians. The question is which cloud provider to use, how much it costs, and whether Australian NBN upload speeds make it viable for your data volumes. Here is what matters in 2026.

Backblaze B2 is the default recommendation for most Australian NAS users. At approximately $8 AUD per TB per month with generous free egress, it offers the best value for NAS backup. The lack of an Australian data centre means slightly higher latency, but for scheduled overnight backups this is irrelevant. Throughput matters more than latency for large transfers, and B2 saturates most Australian upload connections without issue. Both Synology Hyper Backup and QNAP HBS 3 support B2 natively. Duplicati and rclone support it via the S3-compatible API.

AWS S3 Sydney region is the choice for Australian businesses that need data sovereignty (data stays in Australia) or low-latency access to cloud backups. It is significantly more expensive than B2 for storage and egress, but having data in a Sydney data centre means faster restores and compliance with Australian data residency requirements. Synology Hyper Backup, QNAP HBS 3, Veeam, and rclone all support S3 natively. For small businesses with compliance requirements, the premium is worth paying.

Wasabi offers no egress fees and predictable pricing, but requires a 1TB minimum storage commitment (approximately $11 AUD/month). If you are backing up more than 1TB of data, Wasabi can be more cost-effective than B2 when you factor in restore/egress costs. The S3-compatible API means it works with every tool that supports S3. Wasabi has data centres in the Asia-Pacific region (Tokyo, Osaka, Singapore) but no Australian data centre as of February 2026.

Synology C2 Storage integrates seamlessly with Hyper Backup. Select it as a destination and it works with minimal configuration. The convenience comes at a price premium over B2, and data is stored in European data centres. C2 suits Synology users who prioritise simplicity over cost optimisation and are not concerned about data residency. It does not work with QNAP, Asustor, or third-party backup tools. It is Synology-only.

NBN Upload Realities for Cloud Backup

Australian NBN upload speeds are the single biggest constraint on cloud-based NAS backup. Here is the reality in 2026:

The critical number: on the most common NBN 100 plan, your upload speed is 20 Mbps. That is approximately 9 GB per hour. An initial seed of 4TB of NAS data would take roughly 18 days of continuous uploading at full speed. And you would not want to run it at full speed because it would saturate your upload bandwidth and make video calls, gaming, and other real-time services unusable for everyone on your network.

Practical strategies for managing the initial cloud backup seed on NBN:

• Bandwidth limiting: Set your backup tool to use 50-70% of available upload during business hours and 90-100% overnight. Hyper Backup, HBS 3, Duplicati, and rclone all support bandwidth scheduling.
• Prioritise critical data: Do not back up your entire NAS to the cloud. Back up irreplaceable data first. Documents, photos, financial records. Media files that can be re-downloaded (movies, music) are low priority for offsite backup.
• Stagger the seed: Start with your most critical folder, let it complete, then add the next folder. A phased approach over 2-4 weeks is more manageable than a single 4TB upload.
• Consider NBN 100/40: If your RSP offers it and your connection type supports it, upgrading to a 100/40 plan doubles your upload from 20 to 40 Mbps. Aussie Broadband, Superloop, and Launtel offer 100/40 plans.
• USB seed (advanced): Some cloud providers accept a mailed USB drive for initial seeding. AWS Snowball is the enterprise version. For consumer-scale data, this is rarely practical in Australia.

Setting Up Your First NAS Backup. Step by Step

Regardless of which NAS brand and backup software you use, the setup follows the same logical steps. Here is a practical walkthrough for the most common scenario: backing up a NAS to Backblaze B2 cloud storage.

Step 1: Create a Backblaze B2 Account and Bucket

Sign up at backblaze.com. Create a new B2 bucket. Name it something descriptive like mynas-backup-2026. Set the bucket to private (not public). Enable file versioning if you want to retain previous versions of backed-up files. Create an Application Key with read/write access to the bucket only. Do not use the master application key for backup tasks. Note down the Key ID and Application Key; you will need these in your backup software.

Step 2: Configure Your NAS Backup Tool

Synology Hyper Backup: Open Hyper Backup from DSM. Click the + button to create a new backup task. Select Backblaze B2 as the destination. Enter your B2 Application Key ID and Application Key. Select your bucket. Choose the shared folders you want to back up. Enable encryption (set a strong password. If you lose this password, your backup is unrecoverable). Configure a schedule (e.g., daily at 2:00 AM). Set bandwidth limiting under the task's settings if needed. Click Apply and the first backup begins.

QNAP HBS 3: Open HBS 3 from QTS. Create a new Backup job (not Sync. Sync is bidirectional and not what you want for offsite backup). Select your source folders. For destination, choose Cloud. Backblaze B2. Enter your credentials and select the bucket. Enable QuDedup if available on your model. Enable encryption. Set a schedule and bandwidth limits. Save and run the first backup.

Duplicati (any NAS via Docker): Deploy the Duplicati Docker container on your NAS (available in Synology Container Manager, QNAP Container Station, or Asustor Portainer). Access the web UI at http://your-nas-ip:8200. Click Add backup. Set encryption passphrase. Select B2 Cloud Storage as storage type. Enter your B2 bucket name and Application Key. Select source folders (map your NAS shared folders into the Docker container as volumes). Set schedule and retention policy. Run the first backup.

Step 3: Verify and Monitor

After the first backup completes, verify it by performing a test restore of a small file. Do this immediately. Do not wait until you need the backup to discover it does not work. Set up email notifications for backup success and failure in your backup tool's settings. Check your Backblaze B2 dashboard to confirm data is arriving and the size matches your expectations. Review backup logs weekly for the first month, then monthly once you are confident the schedule is running reliably.

Which Backup Software Should You Use?

The right choice depends on your NAS brand, your technical confidence, and what you need to back up:

Synology NAS owner, home or small business: Use Hyper Backup for offsite cloud backup and Active Backup for Business to protect your PCs and servers. There is no reason to pay for third-party software. This combination covers the full 3-2-1 strategy at no additional cost.

QNAP NAS owner, home or small business: Use HBS 3 for offsite cloud backup. For PC backup, try NetBak PC Agent. If you need more robust PC/server backup than NetBak provides, add Veeam Community Edition running on a Windows machine backing up to your QNAP NAS share.

Asustor NAS owner: Use Backup Plan for offsite cloud backup. For PC/server backup, Asustor does not offer a built-in agent. Use Veeam Community Edition or the free version of Acronis backing up to a network share on your Asustor NAS.

Mixed-brand environment or advanced users: Duplicati (Docker) or rclone give you vendor-neutral backup that works identically on any NAS. Veeam Community Edition is the strongest option for business environments with multiple servers and workstations.

Enterprise or compliance requirements: Veeam Backup and Replication (paid), Acronis Cyber Protect Business, or Commvault. These add centralised management, SLA reporting, and compliance features that free tools do not provide. Use AWS S3 Sydney region for Australian data residency.

Local Backup: USB Drives and NAS-to-NAS

Cloud backup is not the only offsite option. And for large data volumes on slow Australian connections, it may not be the most practical one. Two alternatives deserve consideration:

USB drive rotation: Connect a USB hard drive to your NAS, configure a nightly backup task (Hyper Backup, HBS 3, or DataGuard all support USB backup), and periodically take the drive offsite. A family member's house, a workplace, a bank safety deposit box. Buy two USB drives and rotate them weekly: one is always connected to the NAS receiving backups, the other is stored offsite. When you swap them, the returning drive gets a fresh backup and the outgoing drive carries the latest data offsite. A 4TB USB HDD costs approximately $150-180 AUD in 2026, making this the cheapest offsite option for large datasets. See our NAS hard drive guide for drive recommendations.

NAS-to-NAS replication: If you have a second NAS at another location (a relative's house, an office), you can replicate data between them. Synology's Hyper Backup supports remote Synology NAS as a target. QNAP's RTRR (Real-Time Remote Replication) does the same for QNAP-to-QNAP. Both require the remote NAS to be reachable. Either via port forwarding, a VPN, or a tunnel service like Synology QuickConnect or Tailscale. NBN upload speeds apply here too. For ongoing replication after the initial seed, this is a powerful solution. Particularly for small businesses with two premises. Initial seeding is best done by physically transporting the NAS to the remote site, letting the backup complete over LAN, then moving it into position. See our remote access and VPN guide for connectivity options and our data migration guide for moving data between NAS units.

Common Backup Mistakes to Avoid

After 20 years in Australian IT, these are the backup mistakes that come up repeatedly:

• Confusing sync with backup: Synology Drive, QNAP Qsync, Dropbox, and OneDrive are sync tools. If you delete a file on your PC, the sync tool deletes it on the NAS. Sync is convenient for file access, but it is not a backup. Use a dedicated backup tool (Hyper Backup, HBS 3, Active Backup) alongside sync.
• Relying on RAID as backup: RAID protects against drive failure. It does not protect against accidental deletion, ransomware, corruption, fire, or theft. RAID is not backup. Full stop. See our RAID explained guide for what RAID actually does.
• Never testing restores: A backup that has never been tested is a hope, not a plan. Restore a file quarterly. Verify the data is intact and the encryption passphrase works.
• Backing up everything to the cloud: Your 8TB Plex media library does not need offsite cloud backup. It can be re-downloaded. Back up irreplaceable data: documents, photos, financial records, business data. Be selective to keep cloud costs manageable and initial seeding practical on NBN.
• No encryption: Any data leaving your NAS should be encrypted before transmission. All the tools discussed in this guide support client-side encryption. Use it. Your cloud provider should never be able to read your data.
• Storing the encryption passphrase on the NAS: If the NAS fails or is stolen, and the passphrase was only stored on the NAS, your offsite backup is permanently inaccessible. Store the passphrase in a password manager or a physically separate secure location.

Ransomware Protection and Immutable Backups

Ransomware is a real and growing threat to NAS devices. Deadbolt and eCh0raix specifically targeted NAS units in recent years. A well-configured backup strategy is your last line of defence when ransomware encrypts your NAS. But the backup itself must be protected from the ransomware. If the ransomware can reach your backup destination and encrypt or delete the backups, you have no recovery path.

Strategies for protecting backups against ransomware:

• Cloud backup with versioning: Backblaze B2 with versioning enabled means even if ransomware overwrites your cloud backup files, previous versions are retained. You can restore from a pre-infection version. This is the simplest ransomware protection for home users.
• Object Lock / immutable backups: Backblaze B2 and AWS S3 support Object Lock, which makes backup files undeletable and unmodifiable for a specified retention period. Veeam supports writing immutable backups to Object Lock-enabled storage. This is the gold standard for business backup. Even if an attacker gains admin access to your backup server, they cannot delete the immutable copies.
• Air-gapped USB backup: A USB drive that is disconnected from the NAS and stored offsite cannot be reached by ransomware. The USB rotation strategy described above provides a natural air gap. The offsite drive is always disconnected.
• Separate backup credentials: Use a dedicated B2 or S3 Application Key for backup that only has access to the backup bucket. Do not use master credentials. If your NAS is compromised, the attacker only gains access to the backup bucket, not your entire cloud account.

Our Drive Failure Risk Estimator quantifies why offsite backup matters. It shows the statistical probability of a drive failure event for arrays of different sizes and RAID types.

Is NAS backup software free or do I need to pay for it?

All three major NAS vendors. Synology, QNAP, and Asustor. Include backup software free with the NAS. Synology's suite (Hyper Backup and Active Backup for Business) is the most comprehensive, covering NAS-to-cloud backup, PC/server backup, VM backup, and Microsoft 365/Google Workspace backup with no licence fees. Third-party tools like Veeam Community Edition and Duplicati are also free. You only pay for cloud storage if you choose offsite cloud backup. Approximately $8-15 AUD per TB per month depending on the provider.

How long does an initial cloud backup take on Australian NBN?

On a typical NBN 100 plan (20 Mbps upload), you can upload approximately 9 GB per hour or 216 GB per day at full speed. A 1TB initial backup takes roughly 4-5 days. A 4TB backup takes approximately 18 days. In practice, you should limit backup bandwidth to 50-70% during the day to keep your internet usable, extending the timeline. Upgrading to an NBN 100/40 plan (40 Mbps upload) roughly halves the time. After the initial seed, incremental daily backups are much smaller. Typically 20-50 GB for an average home NAS. And complete within a few hours overnight. For a detailed planning breakdown covering all NBN plan tiers and data volumes, see How Long Does a NAS Backup Take?

Can I use Synology Hyper Backup with a QNAP or Asustor NAS?

No. Hyper Backup only runs on Synology NAS devices. Similarly, QNAP HBS 3 only runs on QNAP NAS, and Asustor DataGuard only runs on Asustor NAS. Each vendor's backup software is exclusive to their platform. If you need vendor-neutral backup software that works across any NAS brand, use Duplicati (free, runs in Docker on any NAS), rclone (free, command-line), or Veeam Community Edition (free, runs on a separate Windows machine and backs up to any NAS via network share).

Should I back up my entire NAS to the cloud?

Usually not. Be selective about what goes to the cloud. Focus on irreplaceable data: documents, photos, financial records, business files, and critical project data. Media files that can be re-downloaded (movies, TV shows, music from streaming services) do not need cloud backup. This approach keeps cloud storage costs low and makes the initial upload feasible on Australian NBN connections. A typical strategy: back up the NAS to the cloud selectively (critical data only), and back up the entire NAS to a local USB drive for full local disaster recovery. See our NAS vs cloud storage guide for a detailed cost comparison.

What happens if my NAS dies. Can I restore from cloud backup to a new NAS?

Yes, but the process depends on which backup tool you used. Synology Hyper Backup requires a replacement Synology NAS to restore. Install DSM, install Hyper Backup, connect to your cloud destination, and run a restore. QNAP HBS 3 similarly requires a QNAP NAS. If you used Duplicati or rclone, your backup is vendor-neutral and can be restored to any NAS or even a regular PC. This is a meaningful advantage of vendor-neutral tools. Your backup is not locked to a specific NAS brand. Restore time depends on your data volume and internet download speed (NBN download is much faster than upload, so restores are quicker than the initial backup).

Is Backblaze B2 safe for Australian users even though the servers are overseas?

For most home users and small businesses, yes. Backblaze B2 is a reputable, well-established cloud storage provider. Your data is encrypted before it leaves your NAS (using Hyper Backup, HBS 3, or Duplicati encryption), so Backblaze cannot read your files. They only store encrypted blobs. The data being physically stored in the US is not a security concern when encryption is properly configured. However, if you have regulatory requirements for Australian data residency (some government, healthcare, or financial sector data), use AWS S3 Sydney region instead. The data is stored in Sydney, and AWS meets Australian privacy and compliance standards.

What is the cheapest way to do offsite NAS backup in Australia?

The cheapest offsite backup method is USB drive rotation. Buy two USB hard drives (approximately $150-180 AUD each for 4TB in 2026), back up nightly to the connected drive, and swap them weekly with one stored offsite. No ongoing cloud storage fees, no dependence on NBN upload speeds. The next cheapest option is Backblaze B2 at approximately $8 AUD per TB per month, which is roughly $96 AUD per year for 1TB of cloud backup. For most home users with 500GB-2TB of critical data, B2 costs less than $200 AUD per year and provides automated, always-current offsite protection without manual drive swapping.
