One day in the near future, I will do exactly this. I've now finally figured out a simple way to do this -- but darn, I forgot to write it down.

Backup just has to record the inode number > for each changed file. The problem is that inode is a machine specific concept. Though it can be simulated, it doesn't exist on Win32 or Mac (well perhaps on OS X). Though this would work nicely as you say, I always like to do things in machine independent ways. > > __Martin > > > ------------------------------------------------------- > SF.Net email is sponsored by: Discover Easy Linux Migration Strategies > from IBM.
