Obtaining correct incremental backups after reversion

All files in a reverted volume have timestamps that are the same as those when the Snapshot copy was created. After a revert operation, incremental backup and restore operations on the file or volume cannot rely on the timestamps to determine what data needs to be backed up or restored.

Steps

1. Perform a base-level backup of the volume after you restore it.
2. When restoring data from tape, use only the backups created after the volume was restored.
