This article discusses archiving Datto device backups to an external drive by using the RoundTrip Wizard. The wizard is accessible in the Synchronize tab of the Datto device GUI.

Using your external drive

Your drive must be healthy to complete a local archive. It should not have mechanical or disk defects.

Running the RoundTrip Wizard for your archive will completely erase the contents of your external drive. Back up any critical data on your external drive before using the RoundTrip Wizard.

Creating the archive

1. Plug your USB drive into a USB port on the back of your Datto device.

2. Under the Synchronize tab in the Datto device GUI, click PERFORM A USB ROUNDTRIP.

Accessing Data

The RoundTrip Wizard will format your external drive with a ZFS file system. The data resides in a ZFS storage pool with any snapshots that you selected (or all current snapshots, if you chose to sync the entire agent/share).

To access your data stored in the ZFS storage pool, plug the archive drive into a compatible Datto device, then contact Datto Technical Support.

If you need to recover data using a device from a different Datto product family (e.g., SIRIS to ALTO), contact Datto Technical Support.

Recovering an encrypted archive

If you encrypt your drive when using the RoundTrip wizard (not recommended for local archives), you must plug the drive into the same Datto device from which the data originated.

Recovering or migrating data from local archives created with the RoundTrip Wizard onto third-party devices using ZFS is not supported.
