Hello,

is the result of a vos dump completely independent of any external data
such as configuration files, volume IDs, etc?

In other words, suppose I performed a dump on some volume on server A. I
then went to server B, which is completely separate (separate cell,
separate site, separate everything), am I guaranteed to be able to
restore the volume?

I understand that things like ACL:s won't be practically preserved
unless the target cell has the same users and groups and all that. But
what I don't want happening in the event of a disaster, is trying to
restore a volume but the tool basically giving up because some file X is
not identical to file X when the volume was backed up, or due to some
other circumstance. I want to be sure that, even in the worst case
senario, I can at least access the files, even if ACLs are FUBAR, having
ONLY the volume dump available (kind of like, whatever happens, a
tarball will always be usable).

Also, is it correct that a "vos backup" does *not* lock out clients from
the volume (as "dump" does)? The administrator's guide does not
explicitly say either way; so I believe it doesn't.

Thanks,

(I still haven't sorted out the problem with getting clients to work. I
once promised I would contribute some documentation, and I haven't
forgotten that, it's just on hold until that's solved.)
