About backing up Lotus Domino databases

When a Lotus Domino backup job is submitted, Backup Exec uses Lotus Domino APIs to obtain the backup of the database. When you back up a DAOS-enabled Domino database, the DAOS NLO files are automatically included. In addition, the transaction logs associated with the Lotus Domino databases are included in the backup only if archive logging is turned at the server. If they are backed up, the archive logs are stored in a separate backup set that is stored within the Lotus Domino database backup set.

The Lotus Domino Agent supports the backup of the following types of files:

  • .ntf – Lotus Notes Template Files

  • .nsf – Lotus Notes Database Files

  • .box – Lotus Mailbox Files

  • .dsk – Cache Files

  • .txn – Transaction log files

  • .nlo – DAOS attachment files


    Transaction log files and DAOS attachment files do not appear in the Backup Exec backup selections view; however, they do appear in restore selections view.

You must back up .nsf, .ntf, and .box files to properly recover Lotus Domino databases. If you want to back up .njf, .ncf, .id, .dic, or notes.ini files, you must select them for backup from the volume in which the Lotus Domino Program directory is located.

Although DAOS and non-DAOS Domino servers use additional Domino-related databases and support files, Backup Exec does not back them up. Domino automatically recreates the items after you restart the Domino servers.

Backup Exec excludes the following support files from backup jobs:

  • daos.cfg

  • daoscat.nsf

  • dbdirman.nsf


You cannot back up databases to devices that are attached to a computer on which the Remote Media Agent for Linux Servers is installed.
