Restore command

Edit online

Use the restore command to restore a database backup from local shadow volumes that are managed by IBM Storage Protect Snapshot to an Exchange Server.

To complete an IBM Storage Protect Snapshot for Exchange Server restore, you must have local registry rights for all versions of the Exchange Server.

When you use the restore command, remember the following guidelines:
  • When you restore inactive backups or active incremental backups, use the /object parameter to specify the name of the backup object to restore. This object name uniquely identifies the backup instance that is managed byIBM Storage Protect Snapshot storage. You can enter a tdpexcc query fcm * /all command to obtain a list of all the active and inactive backup objects.
    If the 
    tdpexcc restore dbname
                           incr
    command is entered (without the /object parameter) to restore multiple active incremental backups, all multiple active incremental backups are restored sequentially. The /object parameter is used to restore only one incremental backup at a time.
  • Use the /eraseexistinglogs parameter to direct the program to erase the existing transaction log files for the database before it restores the database. If you do not specify this option, existing transaction logs are not erased, and might be reapplied when the Exchange databases are mounted. This parameter is only valid when you restore a FULL or COPY VSS backup of Exchange Server databases.
  • Specify /mountdatabases=yes if you are restoring the last backup and you want the database or databases to be automatically mounted after the recovery is completed. Only transaction logs that are contained in the backup is applied to the mailbox database when you run a recovery database restore. You must specify /recover=applyrestoredlogs when you restore a mailbox database to a recovery database. Otherwise, the restore operation might fail.

The graphical user interface provides an easy-to-use, flexible interface to help you run a restore operation. The interface presents information in a way that allows multiple selection and, in some cases, automatic operation.

With Microsoft Exchange Server, you cannot specify the asterisk (*) wildcard character in database names. Databases that contain the asterisk (*) wildcard character in their name are not backed up.

IBM Storage Protect Snapshot for Exchange Server supports the following types of restore:
Full
Restore a full type backup.
Copy
Restore a copy type backup.
Incremental
Restore an incremental type backup.
Differential
