I'm a long time SD user. I just converted from an iMac with tons of storage to a Macbook Pro with SSD and limited storage. As a result, I've started using an app called Expandrive (
http://www.expandrive.com/expandrive) to increase my on board storage space.
The way Expandrive works is by taking your cloud accounts (Dropbox, Google Drive, Amazon S3, etc.) and turning them into virtual volumes. In other words, it makes the Cloud storage space appear as mounted network drives. So, for example, I am now using my Dropbox account as 1TB of extra storage for my Macbook Pro available as a psuedo-local drive. However, I'd like to be able to backup that data, since it doesn't exist as a local drive.
I was hoping to backup the mounted Dropbox drive to a local external hard drive via SuperDuper. However, SuperDuper only sees the drives mounted with Expandrive for purposes of Destination drives. They don't appear as Source drives.
Is there any way to use SuperDuper to accomplish this?
