I'm currently evaluating B&R11 and I'm wondering if I'm doing something wrong. I set up a cyclic backup task that ran overnight to make the first full backup. Took 3 hours to complete. Now, I'm running it again to create a differential backup. I'd suspect this backup would be much quicker than the full backup since little has changed. However, B&R still takes a unusually long time for the diff backup. The size of the new PBF file is barely growing, though, signaling a proper differential backup. It is not taking as long as the full backup, but we're still talking about well over an hour. Is it normal for a differential backup to take this long?
