I have noticed that when I backup a database SS2K8R2 SP2 using compression, when that backup is restored the resultant database will bloat up. The original database data size: 32,470,016 kb, restored database data size: 58,696,704 kb. Now I took a backup of the restored database and restored it to another server and it went to 142,266,752 kb.
From what I’ve found if I don’t compress the backup then I will get exactly the same size database as I started, that is why I asked you if there was a known issue with backup compression.
I have not been able to find the reason as well as not able to shrink the restored database back down to its original size.
