The document describes setting up remote backups from one NAS device to another using Data Guard on ThecusOS. It provides step-by-step instructions for performing full backups, custom backups that select specific folders, and iSCSI backups. For each backup type, the user must first set up the target NAS, then configure the backup task and schedule on the source NAS. Upon completion, the target NAS will contain mirrored copies of the backed up data in the designated shared folder.

Introduction
Data Guard is the powerful backup solution that Thecus provides. Remote backup solutions on the market usually are expensive and requires a
complicated setup. Thecus introduces a remote backup solution that allows you to set up different backup solutions in 1 minute; and of course, it’s
free and built in to ThecusOS. In particular, a “Full backup”, “Custom backup” or “iSCSI backup”, can be set to real-time or scheduled backup according to demand.
In this How-to, we will back up data to a N5550 (demo IP: 172.16.65.131) to N4800 (demo IP: 172.16.65.111)
