l Snapshots—A snapshot is an image of data taken at a single point in time.
Snapshots allow you to view files and folders as they existed at points of time
in the past, so you can, for example, recover from cases where corrupted
source data was replicated to the target. For more information about
snapshots, see the Snapshots section in the Storage Mirroring Recover
User's Guide.
l Enable scheduled snapshots—By default, periodic snapshots are
disabled. If desired, enable snapshots by selecting this option.
Because Storage Mirroring Replicate uses the Microsoft Volume
Shadow Copy service to create snapshots, your source and repository
server must be using the NTFS file system. If you are using a FAT file
system, the FAT volumes will not be included in the snapshot set, and
when the snapshots are reverted, the FAT volume will not be time-
consistent with the NTFS volumes.
l Take snapshots on the following interval—By default, Storage
Mirroring Replicate will take a snapshot of the repository server data
every hour. If desired, increase or decrease the interval between
snapshots.
