Best practices for Backup Exec 2010 Agent for Enterprise Vault and the Backup Exec Migrator

Best practices include tips and recommendations to help you use Backup Exec 2010 Agent for Enterprise Vault and the Backup Exec Migrator effectively. For more information about the Enterprise Vault Agent and the Backup Exec Migrator, see the Backup Exec 2010 Administrator's Guide.

The following best practices help you use the Enterprise Vault Agent and the Backup Exec Migrator effectively:

  • Use the Enterprise Vault service account or an account with rights to access the restore selections as the default logon account. Otherwise, you may have to enter credentials for each Enterprise Vault resource that you restore.

  • Avoid backing up Enterprise Vault folders and databases using SQL and NTFS agents. SQL and NTFS agents can interfere with Enterprise Vault Agent backup jobs and may affect the Enterprise Vault Agent's ability to restore the data.

    Note:

    Normally you cannot select Enterprise Vault entries like NTFS folders and SQL databases for backup. However, you can select Microsoft's Common Internet File System (CIFS) folders on network-attached storage devices where these entities may reside.

  • Back up the Enterprise Vault Directory database after you make any configuration changes in Enterprise Vault.

  • Make sure Enterprise Vault 8.x components are not in Backup mode before you back up the Enterprise Vault 8.x Directory database.

  • Check that the Enterprise Vault 7.x services remain in Read-only mode after you run a backup job or a restore job. If the services remain in Read-only mode, remove the registry flags and restart the services. Symantec recommends this action for failed jobs.

  • Do not allow the backup window and archive window to overlap.

  • Do not allow the backup window and the Backup Exec migration window to overlap.

  • Restore the Directory database in a separate job when you restore an Enterprise Vault installation. After you restore the Directory database, you can restore other Enterprise Vault components and partitions.

  • Restore all Full, Differential, and Incremental backup sets of the vault store database in a single restore job.

  • Run the Enterprise Vault recovery tools after you restore Enterprise Vault. The recovery tools synchronize Enterprise Vault with the newly restored databases.

  • Ensure that the appropriate Enterprise Vault product scripts (SQL scripts) run after a redirected restore job completes, but before the redirected restore job is scheduled again.

  • If you install both the Symantec Backup Exec NDMP Option and the Enterprise Vault Agent, pick only one product to protect an Enterprise Vault partition that resides on NDMP filers.

  • Create separate backup jobs for NDMP backups of Enterprise Vault data. You may see a performance improvement when you use the Symantec Backup Exec NDMP Option.

  • Do not change the recovery model of any database that is created by Enterprise Vault. Enterprise Vault configures each database in full recovery mode when it creates them.

Consider the following best practices when you use the Backup Exec Migrator:

  • Symantec recommends that you regularly back up the Backup Exec catalogs.

    In the event the catalogs become corrupt, you can restore them from backups. After you restore the catalogs, you must re-catalog the storage media on which Backup Exec Migrator data is stored. Re-cataloging the storage media ensures that the latest catalog entries are available.

  • For best performance, configure the Backup Exec Migrator to migrate data to a backup-to-disk folder and then to a tape device by using a duplicate job.

  • In the Enterprise Vault Migration options tab, set the time period for Remove collection files from primary storage to something longer than zero days.

    Setting the time period to zero days causes Enterprise Vault to immediately delete the migrated data from the partition.

    If you set the time period to zero days, Symantec recommends the following:

    • Increase the number of concurrent jobs that are allowed for the backup-to-disk folder you use for migration purposes.

      Increase the number of concurrent jobs based on the following formula:

      =

      For example, if you have two installed tape drives, you should configure the backup-to-disk folder to allow four concurrent jobs.

      Concurrent jobs let the Backup Exec Migrator continue to migrate data to disk storage while tape drives process duplicate jobs in a staged migration environment.

      Note:

      You can increase the number of concurrent jobs that run by increasing the total concurrency level of the backup-to-disk devices.

    • Symantec recommends that you first collect all of the archived files in one collection and migration operation and then migrate them in the next collection and migration operation. This process helps ensure that the Backup Exec Migrator creates a single job for each migration operation, which improves the migration performance.
