Starting with ONTAP 9.4, the maximum number of snapshots has been increased
- Beginning with ONTAP 9.4, a volume can contain up to 1023 Snapshot copies.
- A SnapMirror destination volume can contain up to 1019 Snapshot copies.
ONTAP 9.3 and earlier
The maximum number of Snapshot copies follows:
255 Snapshot copies of a FlexVol volume.
If a FlexVol volume is in a data protection mirror relationship, the maximum number of Snapshot copies is 254 because one Snapshot copy is reserved for use by the relationship during recovery operations.
If a FlexVol volume is in a disk to disk backup relationship, the maximum number of Snapshot copies is 251.
If an Infinite Volume is in a data protection mirror relationship, the maximum number of Snapshot copies is reduced by two because two Snapshot copies are used for the data protection mirror relationship.
