All file retrieve operations start from the Enterprise Vault server console. You cannot restore archived Enterprise Vault data from Backup Exec.
When files are migrated from a partition, Enterprise Vault creates a shortcut in the partition that replaces the migrated file. The shortcut also links to the storage location of the migrated file. You retrieve files by double-clicking their shortcuts in the Enterprise Vault partition itself. If a partition retains a local copy of the migrated files, Enterprise Vault retrieves the files from the local copies. If Enterprise Vault deletes the migrated files because the partition’s file retention period passes, the requested files must be retrieved from Backup Exec storage media.
Table: How migrated data is retrieved
The retrieval process is automatic after you start the operation at the Enterprise Vault server. It requires no user intervention other than perhaps placing a tape in the tape device if you removed the storage media.
