Configuring Lotus Notes fast restores
During Domino restores, the NetBackup for Lotus Notes agent automatically restores any reused transaction logs that are required for recovery. Typically one transaction log extent is restored at a time and recovery is completed for the transactions in that log. Because the restore of the log and application of transactions is a sequential process, the restore and recovery performance is slow. NetBackup prefetches the required transaction logs before recovery. Then multiple transaction logs can be restored at a time and made available for recovery.
Review the following recommendations:
Sufficient disk space must be available for the specified number of logs in the transaction log cache location.
The transaction log cache directory and the Domino transaction log directory should be on the same file system. This configuration ensures that the transaction logs are "moved" to the Domino transaction log directory at the time of recovery rather than being "copied." (Copying is time consuming.)
You should create the cache directory before you start a restore job.
To configure Domino fast restores
- Configure the transaction log cache path.
This location is where NetBackup temporarily stores the prefetched transaction logs.
- Configure the maximum number of logs to restore.
This setting determines how many transaction logs are restored in a single restore job during recovery.
