Been through most of the K documentation/help, and reached the end of the internet. From K documentation, nothing (that I've found) says that BUDR Folder backups **won't** work with synthetic fulls. Checkbox is there to schedule synthetic fulls, but the little icon never shows up on the scheduled machine, like it does with Volume backups.
So what's the answer? Folder backups support synthetic fulls? Anyone? Buehler?
Initally when I started using the synthetic backup anything in the folder will be replicated. I make the mistake of putting a other data into the same folder and it was trying to replicate. So to me it would seem if anything is put into the folder it will replicate offsite.
