Backups - ZyXEL Communications NSA221 User Manual

Chapter 17 Troubleshooting
I want to know how my hard disk is performing.
Use S.M.A.R.T. (Self Monitoring, Analysis, and Reporting Technology) to monitor
hard disks. It detects and reports the reliability of hard disks using standard
indicators, enabling administrators to anticipate possible disk failures. Go to the
Package Management screen to install the S.M.A.R.T. application.

17.17 Backups

I cannot make a backup.
• Check that enough space is available on the external disk. If there isn't you may
need to purge older backups or delete other files on the backup USB disk or NSA
(see Section 10.9 on page
• If you are using BackupPlanner
• You can look at the Backup screen's Last Run Result display.
• If you're backing up to another NSA, another NSA, or a computer, check that
it allows the NSA to write files to it. For a synchronization backup, the target
must be another NSA or another compatible model.
• Check that the NSA is not performing another backup job. Scheduler queues
backups when a different backup is already going on at the time a backup is
scheduled.
The backup does not run at the time configured.
• Check that the correct time is configured on the NSA.
• Check that the NSA is able to access the time server from which it gets the
time; see
