Backup strategies for your configuration

To backup a Rhino SLEE, an administrator will typically use a combination of utilities, depending on backup requirements and the layout of Rhino nodes and the external persistence database. Common approaches include:

Backing up and restoring…​ using…​ to support…​

individual nodes

OS-level facilities such as LVM

…​recovery after a node failure, by creating a snapshot of the volumes containing the Rhino installation and persistence database data files.

Note This approach can be done on a per-node, per-database basis. (A database may need to perform recovery when restoring from a disk snapshot.)

cluster-wide SLEE state

the rhino-export utility (to save the management state of the SLEE), and the rhino-import utility (to restore the state to a new cluster)

…​recovery from a cluster failure, recovery from data corruption, rolling back state to an earlier time, and migrating a cluster to a new version of Rhino.

Warning You should also backup any modified or created files which are not stored in Rhino’s management database (for example, using cron and tar). This applies to modified files under the Rhino installation (such as changes to security permissions or JVM options) and to any important generated output (such as CDR files).

subset of the SLEE state

Partial imports

…​restoring a subset of SLEE state, for example during development, after updating a set of SLEE components.

SLEE profile state

Profile snapshots

…​backing up only the state of SLEE profiles (a subset of the management state of the SLEE).

external persistence database

Standard database tools

…​backing up the contents of the external persistence database.
Tip For many deployments, the combination of disk-volume backups and rhino-export backups is sufficient.
