You are a network administrator for your company. The design team provides you with the following list of requirements for server disaster recovery:

No more than two sets of tapes can be used to restore to the previous day. A full backup of each server must be stored off-site. A full backup of each server that is no more than one week old must be available on-site.

Backups must never run during business hours. Tapes may be recalled from off-site storage only if the on-site tapes are corrupted or damaged.

A full backup of all servers requires approximately 24 hours. Backing up all files that change during one week requires approximately 4 hours. Business hours for the company are Monday through Friday, from 6:00 A.M. to 10:00 P.M. You need to provide a backup rotation plan that meets the design team’s requirements.

A.
Perform differential backups on Sunday, Monday, Tuesday, Wednesday, and Thursday nights after business hours.

B.
Perform incremental backups on Sunday, Tuesday, and Thursday nights after business hours. Perform differential backups on Monday and Wednesday nights after business hours.

C.
Perform a full normal backup for on-site storage on Friday night after business hours. Perform another full normal backup for off-site storage on Saturday night after the Friday backup is complete.

D.
Perform a full normal backup for on-site storage on Friday night after business hours. Perform a full copy backup for off-site storage on Saturday night after the Friday backup is complete.

E.
Perform a full copy backup for on-site storage on Friday night after business hours. Perform a full copy backup for off-site storage on Saturday night after the Friday backup is complete.

F.
Perform incremental backups on Sunday, Monday, Tuesday, Wednesday, and Thursday nights after business hours.

Explanation:
If you begin with a full backup over the weekend, it might make sense to perform differential backups on Monday and Tuesday. By later in the week, the quantity of changes may be such that a differential backup cannot be performed overnight. An incremental backup on Wednesday will likely solve the problem, with differential backups continuing after that. Using this system, the restore times are still minimized, because the maximum restoration would involve tapes from the full, incremental, and one differential backup. If a failure occurred before Wednesday, it may take tapes from only the full and, possibly, a differential backup to restore the system.
