CHAPTER 6 Backing Up, Retrieving, and Syncing Files 6.1 About Backups Backup before you need it. The NAS's multiple backup methods make it easy to follow the 3-2-1 backup rule: • At least 3 copies of data • Stored on at least 2 different media • With at least 1 copy off-site. 6.2 Managing a USB Device and USB Backups Use the USB ports and SD card slot to copy or synchronize files between a connected USB or SD device and the NAS. You can use the USB drive or SD card for off-site backups. • Use the Copy/Sync button on the front panel to copy or synchronize files between a connected USB or SD storage device and the NAS. See Section 17.10 on page 232 to configure the copy/ sync settings. • Use the NAS's Backup screens (Section 27.3 on page 321) to schedule backups of files and folders on your NAS to a USB device or SD card. See Section 14.14.2 on page 194 for an example. 6.3 Remote Backups Use the NAS's Backup screens (Section 27.3 on page 321) to schedule backups of files and folders on your NAS to another ZyXEL NAS or a NAS using rsync. • See Section 14.14.1 on page 192 for an example of backing up to a remote NAS. • Use the Restore screens (Section 27.4 on page 332) to restore previous backups based on the backup job. See Section 14.14.3 on page 196 for an example. • If you deleted an archive backup job or the NAS or the RAID array containing the backup job failed, you can restore by backup files. See Section 14.14.3 on page 196 for an example. 6.4 Internal Backups Use the NAS's Backup screens (Section 27.3 on page 321) to schedule backups of files and folders on your NAS to another folder on the NAS.
