Re: Backup Optimisation and Alexander Fatkulin

Hi Alex

Thanks for the link.
You mentioned something like "it can (and will) affect other things "

I am not a native english speaker and that sentence of your's should it trigger of alarm bells to anyone who is planning to turn on backup optimization on in thier environments ?

on the pythian thread you seem to prefer doing ("more precise thing is to specify “not backed up 1 times”.") modifying the backupscript rather then setting the backup optimization parameter on.

I am not seeing any negative ramifications of turning on the backup optimization on the case outlined by the OP on the pythian thread

regards
Hrishy
