SnapRestore uses Snapshot technology and enables you to recover data from any one of the Snapshot copies stored on the file system in case of a disaster.
What SnapRestore is
You can use the SnapRestore feature to recover data that is no longer available or if you are testing a volume or file and want to restore that volume or file to pre-test conditions.
When to use SnapRestore
You can use SnapRestore to recover from data corruption. If a primary system application corrupts data files in a volume, you can revert the volume or specified files in the volume to a Snapshot copy taken before the data corruption.
Reverting a file to a selected Snapshot copy
Using snap restore to revert a single file to a selected Snapshot copy is practical when the file is so large that you cannot copy the previous file version from the Snapshot copy to the active file system.
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.
