  • Clustered Data ONTAP 8.3

Description

The default configuration for aggregate level snapshots in clustered Data ONTAP is as below:

  • aggregate option nosnap=off
  • aggregate option snapshot_autodelete=on
  • aggregate snapshot schedule is 0 1 4@9,14,19
  • aggregate snapshot reserve is 0

The above configuration results in snapshots being created and maintained as per the schedule. If the aggregate is becoming full, then Data ONTAP will automatically start deleting the snapshots, and no space will be reserved for the aggregate snapshots.

Starting in Data ONTAP 8.3.1, you can no longer create aggregate Snapshot copies using the Data ONTAP command-line interface (CLI).

  • Aggregate Snapshot copies are used only to support the SyncMirror and MetroCluster technologies; they should not be used for data protection purposes.
  • Aggregates created using Data ONTAP 8.3 and later versions have Snapshot copy creation disabled by default.
  • If you have existing aggregates with Snapshot copy creation enabled, you should disable it by using the following command, available in the nodeshell:

aggr options aggr_name nosnap on
