i just did the update from 2.1.11 to 2.1.12
found out that you shouldn't make the backups folder within the plugin folder (no damage done :D, found it out while testing).
the 2.1.12 update deleted the folder that i had set up in a job, and all previous test-backups were lost.
i should have tried what would have happened if i had run the job right after the update, but it's history now.
anyway, it's great plugin if you use it in the right way
