[OpenAFS] Backup-strategy

[Craig_Everhart@transarc.com]

So what you want is to make your own volumes to shadow the user's volume.

Do this by creating a shadow for every user volume:
	vos dump user.foo | vos restore user.foo.shadow
where user.foo is at the satellite site and user.foo.shadow is at the
central one.  Do incremental dumps of user.foo data every day, restoring
them to user.foo.shadow
	vos dump -time XXXXX user.foo | vos restore user.foo.shadow

Do all your backups of user.foo.shadow data.  It doesn't even have to be
mounted if you're using vos dump to back it up.  If you're using
something else, you get to create a shadow mount tree.

If you want to be even nicer to your users, do "vos backupsys" to make
local (satellite) clones of all the user.foo volumes, then do your
dump/restore from the backup volumes to the shadow ones:
	vos backup user.foo
	vos dump -time XXXXX user.foo.backup | vos restore user.foo.shadow

This avoids the .readonly headaches and puts the storage where you want it.
