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
Correct Answer: D

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.
