[K12OSN] low tech solution needed for backing up home directories

[Carl Keil]

Hey,

Does anyone have a nifty solution for backing up home dirs?  All the 
users are using Samba only.  I only have about 20 users.  But I'd like 
one of the users (kindof the school power user) to be able to drag 
copies to her workstation once a week or so for safety.  I was trying to 
get a "postexec" command to tar each persons home dir when they log 
out.  But it's not working and I have no idea how to troubleshoot it.  
(People are connecting from Macs mainly and I'm wondering if the Mac 
ejecting the drive even counts as a "log out".)  Any ideas?  How are 
folks without tape drives or a backuppc server backing up home drives on 
a smaller network.  I need an ingenious solution.  I'm looking at cron 
next, but I've never made my own cron script before, I've only typed in 
commands that I've found in online documentation for various programs, etc.

Thanks a million,

ck
