I have had previous versions of the plugin running perfectly for a year or so on 3 WP sites. running WP 3.5.1. The new version 3.0.4 seems to ignore the jobs TO:Folder File Deletion Setting and just fills the disk with different versions of the backups until everything stops due to lack of disk space. The backup folder has not changed. The folder exists and and the backup files are being created in the folder. The logs are purged to the correct number of files.
I have checked the logs. They are not showing the delete attempt has failed for some reason or another. They all have status ok.
I have a look at this forum.
