The Database Maintenance option enables you to manage the Backup Exec database and the Desktop and Laptop Option (DLO) database. Each database maintenance operation is performed independently on each database. The Backup Exec database maintains a record of files and data you have configured such as templates and catalogs.
You do not have to select all the options; however, each one performs a different process that enables you to protect and maintain your database. Selecting all the options enables you to recover the database quickly and maintain optimal performance.
