I don't know of anyone who actually relies upon uvbackup/restore for their backup/restore strategy.
Other than supposedly support "online" backups and checking file integrity - I would see it's relatively slow speed as another reason not to utilise it. Other DB vendors tools tend to suffer from similar such drawbacks as well... The only other comment I'd make is that you don't mention of your AIX rmt device block size was set to automatic or not. This may potentially be the cause of some of your issues?

The results were interesting, and somewhat alarming - see http://gdoesu2.wordpress.com/2011/05/02/facts-about-uvbackup-and-uvrestore/ for details. What I am interested in is: a) Do UV platforms other than AIX and Linux have similar issues with uvrestore? b) Does anyone use block sizes beyond 1mb for uvbackup and uvrestore? If so, what size and what impact does it have on backup performance?
