View the exhibit to inspect the file system configuration on your server. Your department’s
backup policy is to perform a full backup to a remote system disk on Saturday. On Sunday
through Friday, 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 created since
Saturday’s full backup. Following your company policy, which option describes a valid
procedure for backing up the /data file system to a remote disk named /remote/backup?
A.
On Saturday: zfs create snapshot pool1/data@sat. zfs send pool1/data@sat >
/remote/backup/full On each weekday: Remove the previous daily snapshot. zfs snapshot
pool1/data@daily zfs send –i pool1/data@sat pool1/data@daily > /remote/backup/full
