you're right.... everything works fine now there's still the problem of the incremental backups.... although i have set up my backups with 1 incremental file to keep, the system keeps on backuping a new file everyday... ( i backup a server that stores about 60 .PST Outlook files, with an average size of 200 MB....) Hope a nice solution will be chosen soon ! Keep up the good work Au revoir. Arnaud.

The incremental backup cleanup is not yet implemented. I'm working on
that now. In the meantime you can use 'find' to manually remove the old
files. This command will remove incremental files over 30 days old:
find /var/bobsdata/incremental/your_server/your_share/ -ctime +30 -ctime
-999 -exec rm -v {} ';'
