Hi group, I'm using uvbackup/uvrestore as the system to backup uv accounts. Imho the only tool to perform : - a uvdb backup with binary level <> db integrity. - a cross plateform compatible backup We perform account level uvbackup sent to a local file (uvbackup > accountfile.uvb). I can't talk about block sizes impact.
About perf, I use the option -limit set to 1 ; then uvbackup don't start two process (reader/writer) this is really more quick. I know a problem with Type1 files when uvbackup from unix and uvrestore on windows. uvrestore 'restore' dir and subs-dir on windows like prepared on unix but uvwindows don't "respect" Type1 subs dir ... You must resize Type1 to Type19 on uvunix before uvbackup and uvrestore on uvwin.
