thanks, my last note was meant just to thank you, but then a question slipped in... ; )
I would _love_ to run the conversion on Linux, which I'm sure you're right is much faster. Is it possible then to just copy the VSS repo to a Linux box and get a Linux version of ssphys.exe? Would ssphys have to be compiled from source? Is any part of this documented somewhere? thanks again for your time here David On 10/10/07, Jason Winnebeck <[EMAIL PROTECTED]> wrote: > > David, if you want to keep the topic on the list remember to continue to > include vss2svn users e-mail. > > 40GB sounds huge to me.
