When you view Lotus Domino databases in the restore selections pane, two backup sets appear for each Lotus Domino backup job. The first backup set contains the Lotus Domino databases and the second backup set contains the transaction logs.
Lotus Domino data is usually contained in the most recent backup set. However, some subsequent differential or incremental backup jobs run after a full backup job may not contain data in the backup set because only the transaction log was backed up. If the data you want to restore is not located in the most recent backup set, check the previous backup sets until you find the data.
If a new DBIID has been assigned to databases and you run a differential or incremental backup, the data will be contained in the most recent backup set since transactions with the new DBIID will not match the old DBIID.
For example, the Domino server has a Full backup and a Differential backup. If you decide you want to restore data from Differential backup, you may select the Data1 directory and find that it is empty.
