Using a backup replica
To back up a VOB consistently, the ClearCase® administrator must lock the VOB. However, many administrators cannot find convenient times to lock the VOB so that the lock does not interfere with development work. One solution is to use MultiSite to create a replica of a VOB in the same local area network as the original.
Updates from the original VOB to the backup replica are scheduled to match the recovery characteristics desired, that is, how much development work you can afford to lose. At backup time, the backup replica is locked and backed up, thereby not interfering with development work at the original VOB.
