Preparing to recover using snapshots from archived media

Components of SnapManager backup sets

SnapManager backup sets consist of the snapshots of the virtual disks that store the Domino Data directory, transaction log files, and SnapInfo directory that is created as part of the backup operation. All of these components must be archived for you to successfully recover and implement a point-in-time restore.

Type of restore available

Any restore from archive is a point-in-time restore. That is, the Data directory can be recovered only up to the point at which the backup set was created. A point-in-time restore does not include current transactions, so data loss will be incurred. For example, if you created a backup set a week ago, archived it to tape last night, and restored it this morning from archive, the Domino Data directory after the restore this morning are in the same state they were in a week ago.

Rules and guidelines for restoring

Before you restore a database from an archive, make sure that you understand the following:

The virtual disk files from the archive must be restored into the active file system of the filer's volume.
The drive letter assigned to the virtual disk that is restored must be the same drive letter that was used when the archive was created. For additional information, see Guidelines for archiving.
The transaction logs files that you restore from archive can be located on its own virtual disk or on the same virtual disk as the SnapInfo directory.
You cannot recover a virtual disk or transaction logs files into a read-only file system, such as a snapshot.
