Backing Up and Restoring the Arcsight Database
You can configure automatic backups of the Arcsight Database to protect against data loss or corruption. The backed up data can be restored anytime to the same or separate system as per your requirement.
The database uses a single communal storage location for all data and for the catalog (metadata). Communal storage is the database's centralized storage location, shared among the database nodes. When you perform a backup, data gets copied to a backup communal storage location that replicates the live communal storage.
