[rdiff-backup-users] issues moving the backing store

[Dave Steinberg]

Hi all, first let me say that I am already very much enamoured with
rdiff-backup.  I like its features very much and for my uses I think it'll
make for a very efficient, economical backup method.

My problem is that I have recently moved my backing store containing 4
directories (root, var, usr, and home - maybe 1.5 gigs of data) which I used
to sync my machine against.  The move was from a sparc 20 running OpenBSD to
a Ultra 5 running OpenBSD (both are 3.2 -stable or later).  The machine
being backed up is an x86 running OpenBSD 3.2-stable.  Yeah, I like OpenBSD.
:)

I performed the copy by typing:

dump -0af - /backup | ssh address@hidden '(cd /backups ;
restore -rf - )'

This method seemed the least intrusive to me - I didn't want symlinks, hard
links, pipes, or *anything* get to corrupted.

The problem I am observing is that when I try and rdiff-backup against this
new backing store, I get memory faults, core dumps, and the like.  I have
several lovely python cores laying around that I can provide if they are of
interest to anyone.  A few lines of the error are included at the end.  I
can provide more if it would be illustritive.

I thought maybe this was a 'Python on OpenBSD' thing, so I tried starting
from scratch with the /var partition - it copied it over just fine.  This is
what led me to believe that the backing store had somehow been corrupted.

Are there any known issues with moving a backing store?

Thanks and any help or pointers to docs are appreciated!
