Oracle Exam 1Z0-820 Topic 9 Question 86 Discussion

Actual exam question for Oracle's 1Z0-820 exam

Question #: 86
Topic #: 9

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?

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

BRemove 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%'

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

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

Wait, are we sure we can't just use 'rsync' for this? It would be so much easier than all these ZFS commands. I'm joking, of course, but seriously, ZFS is the way to go here.

Hmm, option D looks a bit off. Isn't 'zfs create' used to create a new file system, not a snapshot? I think I'll stick with option C.

I think option C is the correct choice. It involves removing the previous daily snapshot and sending the incremental backup to the remote disk.

This is a tricky one, but I think option C is the way to go. The syntax looks solid, and it covers the key requirements. Gotta love those ZFS snapshots!

Option A seems to have the right idea, but I'm not sure about the use of the '-i' flag in the zfs send command. Shouldn't we be using the '-I' flag instead?

I think option B is the way to go, but the date format in the filename is a bit confusing. Maybe we can use a more standard format like YYYYMMDD.
