You can use Microsoft SQL Enterprise Manager to maintain all the Enterprise Vault databases, but if you have other tools that you prefer to use, you can use those instead. For more information on using Microsoft SQL Enterprise Manager, see the Microsoft SQL Server documentation.

Back up all the databases as part of a planned backup procedure. Depending on your procedures, you may decide to truncate the transaction logs after each database has been backed up.

See About Enterprise Vault backups.

You may find that the transaction logs do not need all the disk space that has been allocated to them. If so, you can shrink them to some suitable size. Do not do this until you are sure that you have understood the disk space requirements for the transaction logs.
