[ILUG] OT: mirroring an external drive

[Brendan Kehoe]

I've got a Seagate 1TB Maxtor Central Axis external drive to do 
network-based backups of a bunch of things at home.  My fear, of course, 
is having a single drive doing all of the work, with the single point of 
failure and all that.

Have any of you toyed with using a cron job to do an rsync between two 
disks (network-shared or not) ?  My idea is to have two of them on the 
network, with one regularly sync'd up with the contents of the other.  
As ever, I want to avoid having to rely on the Windows/OSX software they 
ship with it for handling backups of particular shared volumes on the drive.

Thanks for any suggestions,
B
