SVN backup with lvm snapshots and rsync

[Harry Bullen]

I'm looking at using lvm snapshots and rsync to back up a bunch of svn
repositories every night.  The repositories total about 200GB (some
people might have committed movies to svn but I may not fix this)
which is why I want to do this instead of svn hotcopy, which will have
to copy all 200GB every day.  I wanted to know if their is any danger
from doing this, and if anyone might have some advice for me.

Thank you.

Thank you for this advice.  From what I gather  rep-cache.db, can be
regenerated by svn.  If I used rsync and excluded the rep-cache.db
would I then want to run 'svnadmin recover' on these backup or is
rep-cache.db regenerated automatically when the repository is used?
