A.
Mount -F nfs system: /backup / mnt
zfs snapshot pool/data@monday>/mnt/Monday

B.
Mount -F nfs systemB: /backup/mnt
zfs snapshot pool1/data@Monday
zfs clone pool1/data@monday/mnt/Monday

dear all; sorry but i am confuse C and D option. question required create full backup while system active. So first it create backup, then send and other server receive the backup file…

but i go with C option…:-)

The question states to create a full backup.. It doesnt seem like a snapshot is created in option C, so isnt D correct?

gray

Snapshot is already created and “send” sends full snapshot (to send incremental data you have to use ‘send -i’)

bdt

the question states that “Select the option that creates a full backup of the /data file system”

so C is incorrect

go with D
