Backup Errors

System utility errors that occur during backup are reported on the Backup Status tab.

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.

During an Amazon S3 backup, if the Amazon Web Service (AWS) CLI used for backup faces congestion issues with the Amazon authentication server, error messages are displayed in the Details column of the Backup Status tab, and the backup process terminates. Try to perform the backup after some time.

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.
