Creating your file...
This may take a few minutes. Thanks for your patience.
Your file is ready
A snapshot is a read-only, point-in-time image of a volume. The image consumes minimal storage space and incurs negligible performance overhead because it records only changes to files since the last snapshot.
You can use a snapshot to restore the entire contents of a volume, or to recover individual files or LUNs. snapshots are stored in the directory .snapshot on the volume.
In ONTAP 9.3 and earlier, a volume can contain up to 255 snapshots. In ONTAP 9.4 and later, a FlexVol volume can contain up to 1023 snapshots.
|
Beginning with ONTAP 9.8, FlexGroup volumes can contain 1023 snapshots. For more information, see Protect FlexGroup volumes using snapshots. |
