My following answers relate to the cvs version of bobs 0.6.2. There are 
lots of fixes and enhancements there.

/etc/cron.daily/backup.php runs delete_files() in class_cleanup.php.

Yes, /etc/cron.daily.

Running /etc/cron.daily/backup.php manually should tell you if it even 
gets to the cleanup portion. There is an output line just before cleanup:
      print "Incremental cleanup retention days: $retention_days\n";

You could run /etc/cron.daily/backup.php manually and put "echo" or 
"print" commands in class_cleanup.php to figure out what's going on.

It's possible a bug in rsync may be related to your problem. Or it may 
have nothing to do with it.

I routinely experience problems with a bug in rsync version  2.6.2 where 
it tries to create a directory that already exists. Rsync fails and my 
incremental files are not all deleted and no files have been backed up. 
I have to manually run the backup again from the bobs menu until the 
incrementals are cleaned up. The bug has been fixed but it requires a 
patch or upgrade to rsync 2.6.3. The bug is described here: 
https://bugzilla.samba.org/show_bug.cgi?id=1412

If you're using the latest cvs version of bobs, you can look in 
bobs.log. for " make_bak_dir mkdir "<some file name>" failed: File exists

A work around is to add the option --delete-after to the rsync commands 
in the bobs template directory, usually  
/var/www/html/bobs/inc/templates or inc/templates/ from the directory 
where you compiled bobs. This won't help delete the incremental files, 
but it will make sure your files get backed up before deleting the 
incrementals.

Regardless, there are several fixes and enhancements in the cvs version, 
mostly for logging and email notification, plus the backup templates are 
easily configurable.

Hope that helps.
