9.2 NSA Backup Screens

Use the Protect > Backup menus to create data backups to another volume, an external USB
disk drive, or a computer or another NSA over the network.
The NSA deletes old backups according to the backup job's purge policy (see
page 200) before creating a new backup. If you have a backup scheduled to begin at midnight,
then at that time, the NSA deletes files according to the purge policy setting before doing the
back up. If space on the backup NSA is a concern, then configure the NSA to delete old
backups.
After purging old backups, the NSA does not check if enough space is available before backup
commences. The NSA starts transferring files and if not enough space is available, it issues a
log or alert to tell you that the backup failed (due to lack of space) and deletes any files already
transferred.
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.

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