E. Back up and restore the data from tape.
Correct Answer: BCD
Explanation/Reference:
B: Cloning a Snapshot.
A clone is a writable copy of a snapshot, and is managed like any other share. Like snapshots of filesystems, it initially consumes no additional space. As the data in the clone changes, it will consume more space. The original snapshot cannot be destroyed without also destroying the clone. Scheduled snapshots can be safely cloned, and scheduled snapshots with clones will be ignored if they otherwise should be destroyed.
C: Use the following procedure to roll back, or restore, a filesystem or LUN to an existing snapshot.
1. Go to the share or project that contains the snapshot you want to rename.To restore a filesystem snapshot, go to Shares > Shares.
To restore a LUN snapshot, go to Shares > Shares and click LUNs.
2. Hover over the share that contains the snapshot you want to restore and click the edit icon image:edit icon image .
3. Click the Snapshots tab.
4. Hover over the snapshot you want to restore, click its rollback icon image:rollback icon image , and confirm your action.
D: Filesystem snapshots can be accessed over data protocols at .zfs/snapshot in the root of the filesystem. References: https://docs.oracle.com/cd/E71909_01/html/E71919/gprim.html
