Protect Overview Screen - ZyXEL Communications NSA-2400 User Manual

Chapter 6 Protect Screens
NSA backup can only be done to another NAS with the same firmware version
or an external USB disk that was formatted as 'Backup' volume type.
The NSA does not check if enough space is available before backup commences. The NSA
first starts transferring files and if not enough space is available, then it issues a log or alert to
tell you that the backup failed (due to lack of space) and deletes any files already transferred.
The NSA deletes old backups first before a new backup is done (Purge). If you have a backup
scheduled to begin at midnight, then at that time, the NSA checks your Purge settings and
deletes files according to those settings before the actual backup takes place. If space on the
backup NSA is a concern, then configure the NSA to delete old backups.
A full backup copies all files from your NSA to the backup device. It may take some time
depending on how many files you have to back up.
It is not possible to run programs (like FDISK), that access the disk directly, while backup is
running.

To best protect data, you should back up data to another NSA or an external
hard drive, and store in an off site location.
