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
Correct Answer: BC
Explanation/Reference:
C: The incremental forever backup solution provides these advantages:
Reduces the amount of data that goes across the network.
Reduces data growth because all incremental backups contain only the blocks that changed since the previous backup. No comparison with the backup target is needed since only changed blocks are identified.
Minimizes impact to the client system.
Reduces the length of the backup window.
No need to schedule an initial full backup as a separate schedule: the first issue of an incremental forever backup automatically defaults to an incremental forever full backup.
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.
