Backup Errors

System utility errors that occur during backup are reported in the backup status.

Because the backup is live, data is modified while the backup is running. This might cause some system utility errors which are reported in the backup status.

Whenever the backup process encounters an error, the backup process stops; it does not retry the action that caused the error. If the appliance repeatedly reports errors during backup, run the backup at a different time when the CPU and network bandwidth are less busy.

Note: The system utility error “Partial transfer due to vanished sources files” is expected because source files are archived or purged due to retention, often as part of appliance maintenance. If the backup runs during the regular appliance maintenance cycle, it encounters this error.
