BakHelper and svndump

[zoumra]

svn repository

I try to use BakHelper with svn repository.
The process works fine(i.e in the log), but the command bakthat show displays:
2013-11-14T15:16:27 glacier 160 B SVN_HERACLES_wYUoBA.20131114151627.tgz.enc (svn)

The repository is around 4GB..

with BakHelper(SVN_HERACLES_BACKUP_NAME, password=HERACLES_BACKUP_PWD,destination="glacier", tags=["svn"]) as bhsvn:
logging.info(sh.svnadmin("dump",
q="/mnt/data/svnrepo/",
_out="svnrepo.dmp"))

    bhsvn.backup()
    bhsvn.rotate()
