[TriLUG] backup methodology

[Jason Tower]

as long as it's only a couple of gigs, and it's only moving across the lan, i 
wouldn't bother with tar/incremental backups unless space on the backup 
server is really tight.  using the rsync method that jeremy linked to earlier 
is probably the best bet, or just copy the files directly if you're really 
lazy like me.  make a seperate directory for each day of the week and use a 
cron job to copy data to the appropriate directory on the appropriate day.  
that way if you need to restore a file from three days ago you can do it in 
about three seconds.  if you have the space for it save the friday 
directories and rotate them so you always have three or four, that way you 
can go back a month or so if necessary.
