Seriously, I do think that Subversion should be able to handle such commit
sizes or at least fail with an error, but I can't comment on that since I
only version source code.

The first thing you need to do is find a backup where you can 'svnadmin dump'
that very revision. Then you load the content up to and including that
revision into a new repository and take the rest from the live repository.
You will need a switch telling the dump command to perform the later dump
only incrementally.

BTW: I wouldn't backup the hotcopy. The point is that the format of the
repository is platform-dependant (well, at least the BDB one is), while the
format of the dumpfile is explicitly intended to be compatible. Our backup
here is to first hotcopy the repository and then perform a dump on the
hotcopy and move that to a different machine where it's backed up. The
hotcopies remain on the server, because they also contain things like
svnserve configuration and hook scripts, which are not contained in the
dumpfile and to have a hot spare.
