If this script is no longer needed, i think it is not a problem to modify it in order to ensure Windows folder naming compatibility.

I really have a problem with this script which I have to modify each time I update Tuleap...

Manuel,

The Tuleap installation guide still recommends to add these scripts in root crontab.

Formerly, I think that copying repository files was not 100% guaranted (risk of corruption if a transaction is done during copy) and the only safe procedure was dump.

Beside that, this script is interesting for me since a full backup (file copy) is done every week and incremental dump is done daily.
May be, if nobody use them anymore, you can modify the script "/usr/lib/codendi/bin/backup_subversion.sh".
I will not have to edit at each Tuleap update...

Striclty speaking there is no longer need of this script as subversion (with fsfs backend) perform all operations atomically.
It means that a regular filesystem backend is enough to guaranty integrity of the subversion repositories.

In order to know if your repositories are fsfs of bdb you shall look fs-type:
$> cat /svnroot/*/db/fs-type | grep -i bdb

if no output, it means it's all fsfs

I have no news on this artifact.
I have to modify the subversion backup_script at each Tuleap update.

Best regards,
