Backing Up Your System From the Global Zone

You might choose to perform your backups from the global zone in the following cases:

• You want to back up the configurations of your non-global zones as well as the application data.

• Your primary concern is the ability to recover from a disaster. If you need to restore everything or almost everything on your system, including the root file systems of your zones and their configuration data as well as the data in your global zone, backups should take place in the global zone.

• You want to use the ufsdump command to perform a data backup. Because importing a physical disk device into a non-global zone would change the security profile of the zone, ufsdump should only be used from the global zone.

• You have commercial network backup software.

  Note –

  Your network backup software should be configured to skip all inherited lofs file systems if possible. The backup should be performed when the zone and its applications have quiesced the data to be backed up.
