Where should RouterOS backups be stored to maximize safety during upgrades?

• A. Off-device storage
• B. On-device storage
• C. In RAM
• D. On the same SD card

Answer: (A)

Storing backups off the device keeps a restore copy safe even if the router fails or the upgrade corrupts the local storage. Upgrading RouterOS can introduce issues that brick the device or damage its file system; if the backup lives on the same hardware (in flash, on an SD card, or in RAM), a failed upgrade could wipe or render that backup unusable. Keeping backups on a separate system—such as a remote server, NAS, or cloud storage that you can reach via FTP/SFTP/SSH—means you still have a clean copy to restore from even if the router won’t boot or the local storage is compromised. It’s also wise to keep multiple recent backups and verify restorations to ensure you can recover quickly. In contrast, backups stored on-device or on the same removable media share the same failure risks as the running system, making recovery far more fragile.
