svnadumpfilter only the lasts 10 revision

Question

I have a svn repository that I backup with

svnadmin dump myrepo | gzip -9 > myrepo-$(date +"%Y-%m-%d-%T").dump.gz

hourly (I'm a little crazy).

There is a way for dump the last only 10 or 20 revision of the svn?

Thanks

• svndumpfilter has nothing common with revision ranges,
• svnadmin dump can be used with -r LOWER:UPPER option,
• svnlook youngest give you latest revision in repo.
