The goal of a good backup strategy is to prevent the loss of valuable data by ensuring that the data can be recovered from a combination of backup data and transaction log files. The key to any successful backup strategy is to perform regular backups. Although different Lotus Domino installations and databases often require different backup frequencies, all installations and databases should be backed up at regular intervals.
Important! You should plan your backup and recovery strategies before you begin using the Lotus Domino server. If you do not plan these strategies before using the Lotus Domino server, you may not be able to recover your data if a disk failure occurs.
A typical backup strategy for Lotus Domino would be to perform full backups (database files and transaction log files) of the Lotus Domino server on a weekly basis. In addition, incremental backups (ready-to-archive logs and database files with newly assigned DBIID since the last backup) would be performed on a daily basis. The actual frequency of backups will depend upon the average number of transactions in the Lotus Domino server.
To ensure that backup files contain the most current transactions, you should back up your transaction logs more frequently than your databases. For example, you could back up a transaction log once a day and the entire database once a week. If you have to restore the database, the most recently backed up transaction log would then be no more than twenty-four hours old. More frequent transaction log backups would give you files with transactions that are even more current.
