Which two capabilities are provided with the IBM Spectrum Protect incremental forever backup method? (Choose two.)
A . increase the total number of bytes sent to the protect server
B . reduce the time needed to perform a restore of a system
C . reduce the total storage used to save backups of the system
D . provide the ability to use LAN-Free backups
E . perform a point-in-time restore

Answer: B,C

Explanation:

C: The incremental forever backup solution provides these advantages:

B: In addition, the restore process is optimized, as only the latest versions of blocks that belong to a restored backup are restored. Since the same area on the production disk is recovered only one time, the same block is not written to multiple times. As a result of these advantages, incremental forever is the preferred backup strategy.
