I learned long ago to avoid backup programs that store things away in PROPRIETARY ways and fail to DOCUMENT what they are doing.

My be is WD does support this system but you pay for the answers.

This sort of issue is why I changed from such backup software to simpler copy my files to a folder and when I do use software to backup, it's GOODSYNC, SYNCBACK which I get to select what to sync, when to sync and where it all goes.

That way, my files are safe and I don't have to call it in.
