Applies to

  • ONTAP 9
  • Data ONTAP 7-Mode

Answer

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.
