Retain consistent level-0 backups

After you perform the checks described in Verify consistency without errors, create a level-0 backup. Retain this storage-space backup and all subsequent logical-log backup tapes until you complete the next consistency check. Perform the consistency checks before every level-0 backup. If you do not, then at minimum keep all the tapes necessary to recover from the storage-space backup that was created immediately after the database server was verified to be consistent.
