View the Exhibit to inspect the file system configuration on your server.

Your department's backup policy is to perform a full backup to remote system disk on Saturday.
On each weekday, you are to perform an incremental backup to the same remote system disk.
Each incremental backup will contain only data that has been modified since the previous Saturday backup.
The server file systems must remain available at all times and can never be taken offline. The backup must not only provide for the recovery of the most recent version of a file, but must also allow recovery of previous versions of a file.
Following your company policy, which two describe the correct procedure to be performed on Saturday for backing tip the /data file system to a remote disk named /remote/backup?
A. On Saturday:
zfs snapshot pool1/data@sat
zfs send pool1/data@sat > /remote/backup/full
B. On Saturday:
zfs create snapshotpool1/data@sat
zfs send pool1/data@sat | zfs recv remote/backup/ 'date' '+%m%d%y'
C. On Saturday:
zfs create snapshotpool1/data@sat
zfs send pool1/data@sat | zfsrecv remote/backup
D. On Saturday:
zfs create snapshotpool1/data@sat
zfs send pool1/data@sat > /remote/backup/full
