Review the following recommendations when you configure fast restores:
Sufficient disk space must be available for the specified number of logs in the transaction log cache location. ( or LOTUS_NOTES_LOGCACHEPATH specifies this location.)
Symantec recommends that the transaction log cache directory and the Domino transaction log directory 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.)
Symantec recommends that you create the cache directory before you start a restore job.
