A small business with multiple locations is designing a new backup strategy. After performing an
initial full backup, the company wants to send only incremental backups to a NAS share that tracks
the incremental backups and returns the proper data during restores. When each incremental
backup is made, the company plans to send it to tape and then restructure the tapes as necessary.
Which backup technique should they use?

A.
change block tracking

B.
block level incremental

C.
multilevel incremental

D.
incremental forever

Explanation:
Incrementals forever
This style is similar to the Synthetic backup concept. After an initial full backup, only the incremental
backups are sent to a centralized backup server. This server keeps track of all the incrementals and
sends the proper data back to the server during restores. This can be implemented by sending each
incremental directly to tape as it is taken and then refactoring the tapes as necessary. If enough disk
space is available, an online mirror can be maintained along with previous incremental changes so
that the current or older versions of the systems being backed up can be restored. This is a suitable
method in case of banking systems.
