Keep the offsite drive disconnected while stored, preserve older versions rather than mirroring deletions, and test restores. If you need unattended transfers, self-managed object storage is another option, but it still has usage-based storage costs and requires you to manage encryption, retention and account keys.
What makes an offsite backup useful?
An offsite backup is a separate copy stored away from the computer and primary location it protects. A common target is the 3-2-1 approach: three copies of data, on two media types, with at least one copy off site, as described in Backblaze’s NAS guide. Geographic separation helps protect against a local event, while keeping a copy disconnected can limit the damage from ransomware or accidental deletion reaching connected storage.
Plan for recovery, not just copying. A backup that has never been restored may be incomplete or unusable. Include both individual-file and larger-folder restore tests in your routine.
Option 1: Rotate two external drives
This approach avoids a cloud storage bill, but requires you to transport and safeguard the drives. A directly connected USB or FireWire drive can serve as a backup volume; for Backblaze’s external-drive workflow, the drive must be directly connected and natively readable and writable by the computer (Backblaze’s external-drive requirements). Choose a filesystem your computers can read and write without relying on special software.

- The available storage capacity may vary.
Set up the drives
- Estimate how much data you need to protect, including retained older and deleted versions. Choose two drives with room for that data and future growth; there is no universal capacity figure because the right size depends on your data and retention policy.
- Label the drives A and B. Format each in a filesystem natively supported by the computers that will create and restore backups.
- Create a backup job using your operating system’s scheduler or a backup application. Configure it to retain deleted files and older versions rather than immediately reproducing destructive deletions on the backup.
- If a drive or backup archive could be lost or accessed by someone else, encrypt it. Keep recovery keys somewhere separate from the drive, and make sure you know how to use them before relying on the backup.
Run a rotation
- Connect Drive A at the primary site, run the backup, inspect the job’s logs for errors, and restore a sample folder.
- Disconnect Drive A and store it at a different location. Keep it disconnected while stored.
- At the next rotation, bring Drive B to the primary site, update it, check the logs, and test a sample restore.
- Return Drive B to the offsite location. Record each drive’s last update date and current location, and repeat the exchange on a schedule you can maintain.
Set the rotation frequency according to how much recent work you could afford to lose. The 30-day reconnection rule sometimes cited for detached drives is specific to Backblaze Computer Backup’s default Version History setting, documented in 2023; it is not a universal backup interval (Backblaze’s version-history documentation).
Option 2: Back up to self-managed object storage
Object storage can automate offsite transfers without buying and carrying drives, but it is not subscription-free in the sense of having no ongoing cost: storage use and possibly data retrieval are governed by the provider’s current pricing and terms. You also take responsibility for configuration, encryption, retention and access credentials. Backblaze B2 Cloud Storage and Backblaze Computer Backup are separate products, not two names for the same plan (Backblaze integration overview).

Configure a protected upload
- Create an object-storage account and bucket, then generate a restricted application key for the backup tool. Backblaze’s integration guides put account, credential and bucket setup before tool configuration (integration guides).
- For rclone, run
rclone config, choose the B2 backend, and configure it with the application key rather than a master key where possible. Backblaze recommends rclone as an rsync client that supports B2 (Backblaze’s rclone guide). - Use an encrypted backup workflow. rclone’s
cryptlayer or a backup application such as Duplicati, Restic, Arq or Veeam can encrypt data, depending on how it is configured. Backblaze documents these tools and integrations (Backblaze integration guides). - Configure retention or versioning so an accidental deletion or overwrite does not immediately remove the only recoverable copy. rclone documents
--backup-dirand suffix options for retaining changed files; dedicated backup applications may instead provide snapshots and pruning policies (rclone documentation). - Schedule uploads, monitor failures, and periodically download a test restore. Keep a separate local backup too: a cloud copy by itself does not make a 3-2-1 layout.
Backblaze estimated that setting up an integration takes about 15 minutes after prerequisites are complete in its 2026 “Get Started with a Backblaze Integration” guide. That is an estimate for integration setup, not a guarantee that a complete, tested backup will be ready in that time (Backblaze integration guide).

| Consideration | Rotating external drives | Self-managed object storage |
|---|---|---|
| Cost pattern | One-time hardware purchase; no cloud storage bill. | Usage-based storage costs, with current pricing and any retrieval charges depending on provider and use. |
| How it runs | Requires physically exchanging drives and connecting them for updates. | Can run unattended after configuration, but failures still need monitoring. |
| Recovery | Recovery depends on having the current drive at hand; restoring locally can avoid downloading from a provider. | Requires internet access and downloading data; recovery time depends on connection speed and data volume. |
| Security responsibilities | Protect the drive from loss, theft and environmental damage; encrypt it and keep recovery keys separate. | Protect application keys, configure encryption and retention, and monitor account access. |
| Good fit | People who can exchange media and prefer predictable one-time hardware costs. | People who need remote access or unattended transfers and accept ongoing usage costs and setup responsibility. |
A NAS can provide a central local backup target for several computers. Backblaze documents Synology Hyper Backup and QNAP integrations for transferring NAS data to B2 (Backblaze integration guides).

Keep the backup recoverable
- Keep at least one copy disconnected or otherwise protected from compromise of the live system.
- Keep an offsite copy in a different building or geographic area.
- Record drive labels, update dates, storage locations and instructions for recovering encryption keys.
- Test restoring both individual files and a larger folder on a regular schedule.
