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. 
  | 
||
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. 
  | 
||
subset of the SLEE state  | 
…restoring a subset of SLEE state, for example during development, after updating a set of SLEE components.  | 
|||
SLEE profile state  | 
…backing up only the state of SLEE profiles (a subset of the management state of the SLEE).  | 
|||
external persistence database  | 
…backing up the contents of the external persistence database.  | 
| 
 | 
For many deployments, the combination of disk-volume backups and rhino-export backups is sufficient.
