assuming that you do have rcs/cvs properly working ...
what would you do with it ??
today is Dec-18
in the cvs tree, you say "restore Nov 13"
and what happens to all your files you did NOT wish to restore
backwards
if you manually specify, just "restore server1:/etc/sources.list"
than why is that any different than using tar ??
server1# cd / ; tar zxvfp /n/server1/etc/sources.list
you can restore manually .. ( probably a good idea ) vs using a gui
that you might not be able to control, or test the files it will
be restoring/extracting before it does it
keeping a tar file of everyday's changes is good enuff ??
which allows you to recover to any particular day from a working
full backup
- if you cannot guarantee several ways to maintain a working
full backup, than all incremental changes is worthless
- i'd spend the time to guarantee "full backups" are NOT
corrupted or "disk/tape full" instead of worrying about
restoring/tracking "one" file or "one cvs tree"
- you know your daily cvs treee or backup is working because you
time stamp each directory after each directory or server is done..
touch /home/user/...Backup.Done
- backup scripts are all FREE ... and all require tweeking, which
users and servers you want to backup to where
