nop, I'm using svn dump every day, and svn hotcopy every week, always
from the real repository.

sure. by the way, the "current" backup always stays near the
repository after it has been scp'ed to the backup server, and the
hard drive of the server hosting repositories is backed up on a
dedicated hard drive every night.

the backup server use a RAID 50 drive bay, so it's quite safe (on the
hardware front)
once a month every server is backed up on DVD, and their backup HD is
removed for off-site storage
... and so on, I've just talked about svn "dedicated" backup,
everything is under global backup policy beyond the scope of this thread

we don't code here, we store on SVN only some homemade shell scripts,
config files for our 20 servers, notes and howto's for administration
purposes. The most sensitive data is an encrypted password file. For
a bunch of files used by 2 sysadmins it's a quite paranoid backup
process.
