To back up the CTERA Portal servers and storage you need to use third-party recovery tools.
If the storage fails and you need to use the backup storage, you need to change the definition of the storage node to point to the backup storage bucket in the CTERA Portal.
For the CTERA Portal database backup, see Configuring the CTERA Portal Database for Backup.
Using third-party tools can result in a recovery of the storage after a disaster not being consistent with the portal database with the storage recovery being either older or newer than the portal database recovery, which is described in Configuring the CTERA Portal Database for Backup.
If the storage recovery is older than the database, it can be missing some recent blocks. In this situation, you should rollback the portal database to an earlier point-in-time that matches the storage recovery.
If the storage recovery is newer than the portal database, since deleted blocks are kept for a minimum of 30 days and these blocks are never modified, as long as the portal database is no more than 30 days older, there will be no data loss.
Running CTERA FSCK is usually recommended following a disaster recovery. CTERA FSCK must be run only with approval from CTERA support.
