Recovery process in RUV

To perform a RUV forward recovery, you must have a valid backup of the VSAM data and the archive and the files must be registered in the RUV repository.

The RUV recovery process is shown in the following figure:

When you specify a recovery point, RUV determines which backup (or backups) and archive (or archives) to use.

• If the recovery point corresponds to the time of a crisp backup, RUV simply restores the backup.
• If the backup was a fuzzy backup, RUV restores the backup and applies the transactions (journal data) that occurred from the start of the backup until a point in time after the completion of the backup. With the combination of the fuzzy backup and the journal data, the integrity of the data is maintained.
