Description
Backup creates a point-in-time copy of the current in-memory metadata without activating it. The new meta-volume is named:
current-metadata-namebackup_yyyyMMMdd_HHmms
Metadata is read from the meta-volume only during the boot of each director.
Create a backup meta-volume:
● As part of an overall system health check before a major migration or update.
● If the system permanently loses access to both meta-volumes.
NOTE:
No modifications should be made to the system during the backup procedure. Make sure that all other users are
notified.
Use the ll command in the system-volumes context to verify that the meta-volume is Active and its Ready state is
true.
