How Do I Use The RoundTrip Wizard To Create A Local Archive From A Datto Device?



How do I use the RoundTrip Wizard to create a local archive from a Datto device?


  • Datto SIRIS
  • Datto ALTO
  • Datto NAS


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

Using your external drive

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

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

Encrypting the contents of your drive can cause delays or compromise the ability to access your data. Do not check the Encrypt Drive option when processing a local archive.

To select all points in a backup chain for local archiving:
1. Select Advanced Options.
2. On the Advanced Options screen for each desired agent, double-click the padlock icon to unlock the selection, click the bottom-most point, then click the top-most point.

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.

  • ALTO 1 archive drives are only compatible with other ALTO 1 devices.
  • G-Series devices with OS 2.x devices do not ship with the local archive functionality but can mount SIRIS 1 archive drives.
It is not possible to mount data for recovery between devices belonging to different groups listed above. Contact Datto Technical Support if you need to recover data using a device from a different Datto product family (e.g., SIRIS to ALTO). 

Recovering an encrypted archive

If you opted to 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.
