Plesk starts backups every night without initial interaction

[PaulaC]

Hi there,

I'm running Plesk 10.4.4#47 on CentOS 6.3. Since yesterday my customers complain about their exceeded webspace. I noticed that Plesk backups every domain at night, but the backup jobs weren't configured by the users! When I open a customer's control panel and look at backup manager there's no backup job active, but I see that Plesk started to backup since the 15th of January.

What could be wrong?

Best,
Paula
