Humm,, it seems that LBackup will copy folders and set up an image file
(may be zipped) when running a snapshot.

So I think it will sacrifice disk space for multiple snapshots, right?

Yeah, I think this is reasonable. Cause each file have a life cycle. If
we set "numRotations=?" properly.

I have just browse the source code. There are quite a few scripts, which
might be running under linux,right?


I found that there are only Mac OS installer avaliable for users. I
checked
http://connect.homeunix.com/lbackup/operating_system_specific_builds.

Is there any version available for Windows XP?
