Since updating to DSM 6.0.1-7393 and reinstalling iDrive 2.03.20 I am only able to backup shared folders. Previously I was on DSM 5 with the same version of iDrive installed and I was able to backup any folder under /volume1. Specifically the @appstore folder. iDrive support is telling me you can only backup shared folders but when I check my backups in the cloud I have a /volume1/@appstore backed up out there. This was one of the main reasons I picked iDrive over other backup solutions and now it's not working.
Anyone else seeing this?
