I've installed the cvs version of bobs and have manually run the
backup.php script. I now see many screenfulls of this:</font><br>
<tt></tt><br>
<br>
<b>Warning</b>: unlink() failed (Is a directory) in
<b>/var/www/html/bobs/inc/class_cleanup.php</b> on line
<b>95</b><br /><br>
Unable to remove /backup/bobsdata/incremental/main/homedirs//<br>
<br /><br>
<b>Fatal error</b>: Maximum execution time of 30 seconds
exceeded in <b>/var/www/html/bobs/inc/class_cleanup.php</b>
on line <b>89</b><br /><br>
<br>
It's failing to remove something. Is this just a one time thing or an
indication of something else?<br>
<br>
Thanks<br>

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.

<br>
Yes, /etc/cron.daily.

<br>
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:
<br>
print "Incremental cleanup retention days: $retention_days\n";
<br>
<br>
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.
<br>
<br>
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:
<a class="moz-txt-link-freetext" href="https://bugzilla.samba.org/show_bug.cgi?id=1412">https://bugzilla.samba.org/show_bug.cgi?id=1412</a>
<br>
<br>
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
<br>
<br>
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.
<br>
<br>
Regardless, there are several fixes and enhancements in the cvs
version, mostly for logging and email notification, plus the backup
templates are easily configurable.
<br>
<br>
Hope that helps.
