For this specific example you could probably wildcard match the files with a
--exclude= argument. Borked filesystems usually generate matchable files. For
a more generic test:
if [ `du -sb <root>` -gt <size limit> ] ; then <barf>; else <rsync>; fi
Which is crude, time-consuming and won't transfer anything if you step even
one byte over the limit. How evil do you want to be? :)
You could get your script to parse file-from before hand and maybe only backup
the entries that come in under the limit. Perhaps build the full file list
yourself, incrementing a counter each file until you reach the size limit then
fire off rsync with that new list passed to --files-from.
Again, not very elegant, but it'd do the job. This also assumes you're running
something unixy (Doing this stuff in batch a whole new level of hell).
