which two describe the correct procedure to be performed on each weekday for backing up the /data file system to a remote disk named /remote/backup?

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

You department’s backup policy is to perform a full backup to a 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 each
weekday for backing up the /data file system to a remote disk named /remote/backup?

A.
Remove the previous daily snapshot.
zfs snapshot pool1.data@daily
zfs send-i pool1/data@sat pool1/data@daily > /remote/backup/full

B.
Remove the previous daily snapshot.
zfs snapshot pool1.data@daily
zfs send-i pool1/data#sat pool1/data@daily | zfs recv remote /backup/ �date �+%m%d%�

C.
Remove the previous daily snapshot.
zfs snapshot pool1.data@daily
zfs send-i pool1/data@sat pool1/data@daily > /remote/backup/daily

D.
Remove the previous daily snapshot.
zfs create-i pool1/data@sat pool1/data@daily
zfs send pool1/data@daily | zfs remote/backup

Explanation:
You can use the zfs send command to send a copy of a snapshot stream and
receive the snapshot stream in another pool on the same system or in another pool on a different
system that is used to store backup data.
You can send incremental data by using the zfs send -i option.

For example:
host1# zfs send -i tank/dana@snap1 tank/dana@snap2 | zfs recv newtank/dana
Note that the first argument (snap1) is the earlier snapshot and the second argument (snap2) is
the later snapshot. In this case, the newtank/dana file system must already exist for the
incremental receive to be successful.
The incremental snap1 source can be specified as the last component of the snapshot name. This
shortcut means you only have to specify the name after the @ sign for snap1, which is assumed
to be from the same file system as snap2. For example:
host1# zfs send -i snap1 tank/dana@snap2 > zfs recv newtank/dana
This shortcut syntax is equivalent to the incremental syntax in the preceding example.
