Restoring Lotus Domino databases

Restoring a Lotus Domino database is a three-part process.

Table: Restoring a Lotus Domino database



Step 1

Restore database files to the Domino server.

During a restore of the Lotus Domino database, the existing database is taken offline and deleted, the database is restored, and changed records contained in the backup job are applied to the database.


Domino servers include databases with names such as admin4.nsf, names.nsf, and busytime.nsf. The Notes client computers include databases with names such as bookmark.nsf, cache.dsk, and homepage.nsf. These databases are critical and cannot be taken offline when the Domino server and the Notes client are running. In addition, you should only restore these databases in disaster recovery situation.

If the database is unlogged or local, the database is brought back online. If the database is logged and multiple databases are being restored, the database name is added to a list for recovery. During the restore process, Backup Exec assigns a unique name to databases and then before databases are brought online, reassigns the original name. Changing the name during the restore process has no effect on restored databases.

Step 2

Restore DAOS-related NLO files that are missing.

Step 3

Run transaction logs to bring the database up-to-date.

The internal Domino recovery process automatically begins after the DAOS NLO files are restored to the server. The database is restored to a point in time using transactions from the required transaction logs. Required transaction logs that were backed up and recycled are also included in the recovery process. After the recovery process completes, the Lotus Domino database is brought online.

If you back up your Lotus Domino databases regularly, then restoring the most recent backup set containing the Lotus Domino data is all that is required to restore the most recent backups of your Lotus Domino databases.


If circular logging is enabled and both the databases and the Domino transaction logs are lost, the database can only be recovered to the point of the last full backup.

Use the same procedures to restore a server in a Microsoft Cluster Server cluster that you use to restore a server in a non-clustered environment.

When restoring a Lotus Domino database to a MCSC cluster and a failover occurs during the restore operation, active restore jobs are paused for 15 minutes as they wait for existing connections to resolve themselves. If the restore job does not restart before the failover time-out period expires, the job fails. If this occurs, the restore job must be resubmitted.
