[OpenAFS] vos shadow to backup user homes

[Shouri Chatterjee]

Dear All,

I wanted to ask about "vos shadow" and whether it is being used 
as a solution on production systems to back-up user home directories.

The most significant information I can find is a thread from this email 
archive last year. 
http://lists.openafs.org/pipermail/openafs-info/2012-December/039077.html

I can dedicate a server to host only shadow volumes. If an active server 
fails and dies, the shadow copy can be brought online. Is this a better 
solution than, say:
(1) keeping a periodically rsync'd copy of the /vicepx partitions on a 
shadow server
(2) afs over drbd

I am trying to use commodity hardware (no RAID, no scope for software RAID 
either) to build cheap AFS storage.
