Virtualmin Backup Error

Hey Guys,

my Virtualmin backup is not working if there’s already a folder.

Structure of Backup-FTP is:


“Create destination directory?” is checked.

If i run the backup on clean server without the virtualmin folder, the backup will be fine, but if there’s already a backup virtualmin shows me this error.

HTTP/1.0 500 Perl execution failed Server: MiniServ/1.570 Date: Wed, 25 Jan 2012 10:38:14 GMT Content-type: text/html; Charset=iso-8859-1 Connection: close

Well, that’s unusual!

In theory, it should be no problem to have an existing directory (that’s in fact what I do on my own server).

If you look in /virtualmin, is there anything unusual about the owner of the directories that already existed?

One simpler thing I might suggest, is that sometimes errors like you’re getting above can happen due to Virtualmin upgrades where Webmin wasn’t properly restarted.

This is a long-shot, but can you try just giving Webmin a restart to see if that fixes it:

/etc/init.d/webmin restart

If that doesn’t help, and you don’t notice anything unusual with the permissions, let me know and we can ask Jamie what he thinks :slight_smile:


Hi Eric,

thank you for your response.

In theory it should work. Existing folders don’t have to be a problem.

I restarted Webmin several times (also restarted the whole system), but the result stays the same. No Virtualmin-backup if the /virtualmin folder exists on backup-ftp.

Here some screenshots from the backup-ftp. User should be 56334.

I found out, if i make the backup on root-level (/virtualmin-%Y-%m-%d) without auto-delete, the backup is working. But i need to delete the old backups, because my backup-space is only around 250GB.
