Although NAS is a file server, it provides secure storage space for your data. Nonetheless, there is a chance of failure of the hard disk and NAS, and your data is still at risk. For safety, it is necessary to make a backup of the important data in the NAS. TerraMaster developed its own new backup tool Duple Backup. Duple Backup can provide you with a variety of backup methods to remotely backup folders or iSCSI LUNs in TNAS to another TNAS, file server, Webdav server, various mainstream cloud disks, and local folders. Duple Backup supports scheduled backup, incremental backup and multi-version backup, and has a one-key restore function. The beta version of Duple Backup is already online, and interested users can install and test it.
To install Duple Backup, please go to TOS > Application > beta. To create a backup task to another remote TNAS, you need to install Duple Backup Vault on the remote TNAS device.
