Configuring Store Maintenance and Backup Options

The maintenance processes and backup options are the same for mailbox stores and public folder stores. You can check and configure these options on the Database tab of the store that you want to check or configure.

The Database tab for a mailbox store

The Database tab for a mailbox store includes the following maintenance and backup options.

• Maintenance interval   Specifies the schedule for the automatic database maintenance process. This process:

  • Checks that none of the storage limit settings have been exceeded on any mailbox or public folder.

  • Sends mail to the administrator or the mailbox owner if storage limits have been exceeded.

  • Checks for deleted items that have been retained for the time configured for the store.

  • Checks for and deletes expired items in the folders if age limits have been set on any public folders.

    Because this process can consume significant server resources, it is a good idea to schedule it to run during off-peak hours.

  Note

  For more information about the settings that the maintenance process enforces, see "Configuring the Default Mailbox Limits," "Configuring the Default Public Folder Limits," and "Configuring Limits on a Specific Public Folder Replica."

• Do not mount this store at start-up   When this option is selected, the mailbox store does not mount automatically when Exchange is started. By default, this check box is cleared.

• This database can be overwritten by a restore   Do not use this option for normal restore operations. Select this option only if a restore operation fails with an error that indicates the database cannot be overwritten. By default, this option is not selected.
