Thanks for the clarification. Although I have been aware of rsync for quite
a while, I must confess to not have actually utilized it. I must make some
time to read the manual... But what about this scenario: Say you have
multiple hosts that each may initiate changes to a file. Can rsync be set up
to sync all host copies to the most recent changed version--regardless of
the host or user that initiates the changes? Can rsync maintain multiple
versions of the same file?
Personally, I have a custom brewed system of software RAID0 and RAID5 volumes in
conjunction with a cvs repository, backed up with a set of custom scripts that I
employ to sync my volumes and even burn CDROMs on a periodic basis. It has
worked well for me, but I am fast coming to the point where a more robust, well
thought out system is needed. So, I'll be re-designing this IT subsystem in the
