Currently the only way to safely copy/backup those databases is to
copy
the files while the server processes are either shut down, or stopped
(with SIGSTOP). You have to copy both the the .DB0 and .DBSYS
files (or
just copy everything in the db directory, which should probably
work no
matter how the databases are changed in the future).
Some people just copy the files while the servers are running,
though, I
think. If your ubik database doesn't change constantly at a high rate,
and you make several copies, it's very likely you'll save at least one
valid copy. It's also possible to add a dbserver just for the purposes
of backing up this data, if you want to go the "safe" route above, but
don't want to interrupt the dbservers that clients actually use.
If you go this route, you can create a non-voting clone to do it, so
there's actually no
chance of disruption.

Thank you for both suggestions!
I'll implement both:
1. Add another clone
2. Already fetched gerrit 9700 and will build it tomorrow.
