Cumulative vs differential backup performance during a restore
I am looking for information regarding the performance of a restore using cumulative incremental vs differential incremental backups. I understand the difference between the two. If the full and incremental backups are to a disk based backup system, i.e. a 5230 netbackup appliance, which full and incremental backup combination is better for a restore, cumulative or differential? I understand in a tape environment that a restore using a cumulative backup will reduce tape mounts but in a disk environment where no tape mount is required, is there a performance improvement when restoring a server using a full and a cumulative incremental backup? If so, how much better is it over a full and differential backup? If anyone can share performance data, it would be appreciated. I am assuming a weekly full and daily incremental backups.
