- Data ONTAP 8
- ONTAP 9
- Root volume (vol0)
Root volume snapshots are legacy default settings from Data ONTAP operating in 7-mode, where recovery options such as restoring root volume to a previous checkpoint and other aspects used root volume snapshots.
In clustered Data ONTAP 8 and ONTAP 9 we use different recovery options, which do not utilize the root volume snapshots any longer, so it is safe to disable them.
