MSSQL backup how's it work exactly?

Hi Mike - .bak method is what I’m doing now but there’s no rdiff tech from rsync in a clean and meaningful way. I’ve tried using cygwin’s rsync on Windows then gzip’ing the .bak files with the --rsyncable option and rsync derps. It doesn’t see any diff. So…I’m hoping the rdiff tech in Duplicati will see the differentials in things like the OS snapshots, SQL snap shots, etc.

I’ll find out by trial here with SQL is going to do. If it dumps everything or just parts with rdiff tech.

Thanks for your feedback. Your thoughts on the .bak process are a viable option also.
