When you use continuous protection as part of your backup strategy, note the following best practices:
If you must copy backup sets to tape for off-site storage, create a job to duplicate backup sets. You can configure the job to copy the backup sets to tape after each occurrence of the full backup job.
If you duplicate Information Store backup sets to tape, and then back to disk, specify the same volume for the full and the incremental backups. The backup sets must be on the same volume to restore individual items from the incremental backup.
After you create and run a CPS Exchange backup job, do not change the backup-to-disk folder that it was run to. If you must change backup-to-disk folders, then create a new CPS Exchange backup job with a new backup-to-disk folder as the destination device. Delete the previous job.
