Product: Plesk for Linux/Unix
Operating System details: Ubuntu 8.04
Plesk Version: 9.2.1

First of all, the Plesk acronis module in Plesk 9.2.1 could not create a full backup.  It would run for a minute and then stop, but, you could create a full backup with the command line acronis tools.

There is a Parallels KB article about this and how to “fix” it:

• Plesk 9.2.1 for Linux Acronis module bug
• [HOTFIX] Acronis backup executed via ATIS module does not create proper backups

However, this introduced another problem, which, after days of trying to get Parallels to look into their support team have not said that “the developers are looking into it”.

The new problem is that scheduled Acronis jobs keep on saying:

Error: another atismodbackupmng process is running!
TrueImage backup task #1

And does not create a full backup.  This issue has been ongoing over a month now and counting.
