ZPanel creates multiple backups on one day

Suddenly my ZPanel began making multiple backups on one day. Looking at the filename of the backup it looks like the backups are made 1 sec after another.

Backup has file names like this

zadmin_Oct-18-2014_051006.zip
zadmin_Oct-18-2014_051007.zip
zadmin_Oct-18-2014_051008.zip
