[Leaplist] Backup to external USB md RAID 1/5?

[Jason Boxman]

To save physical space, I am considering eliminating my backup server 
entirely.  Instead, I am considering replacing it with three external 3.5" 
(the current internal disks) drives in a RAID 1 or 5 configuration.

Can you run md RAID against a bunch of external USB 2.0 drives?  Is that 
working for anyone?  Alternately, is there some other solution that'll 
provide me with live, on-site backups that I can divorce from a physical 
system if necessary.  (If the system itself dies and I need access to the 
backups, not to move the hard disks off-site; I expect to leave them spinning 
24/7.)

Thanks.
