1.2.22.3 Volume Snapshots

A volume snapshot is a thinly-provisioned read-only point-in-time copy of a volume.

Volume snapshots have the following uses:

• You can create attachments to a volume snapshot and use it as a read-only volume.
• You can use a volume snapshot as the source for a volume clone.
• You can use a volume snapshot as the source for a volume backup.

Additionally, starting with Oracle Exadata System Software release 26.1.0, you can lock a volume snapshot to prevent its deletion before a specified future date and time. You can also make the lock immutable, which prevents users from removing the lock or changing it to expire earlier.
