To quote Dmitry from a few weeks ago (around mid Jan. 2012), the usage of nbackup in 2.1 with Classic under high load can be "problematic". It seems that there was quite a re-write in 2.5 though. I have no evidence in respect 2.1 though, except I know one site that quit using nbackup with 2.1.3 and 2.1.4 Classic with ~300 attachments due to stability, corruption problems. Without nbackup, the system is more or less working fine now. Regards, Thomas
