I've tried this with a small 10MB TC volume (just to hold docs). Every time I modified the contents of the TC file DP would upload the entire volume again. So explain this full support for Truecrypt please.

My backup has been worked good for the last few years. I had a large windows tower filled with hard drives...
* One of my HDD was encrypted using Truecrypt.
* A scheduled Acronis task would image my OS drive to the encrypted drive.
* I have another encrypted HDD in one of these KINGWIN KF-91-BK trays (http://www.newegg.com/Product/Product.aspx?Item=N82E16817121172)
* After Acronis was done, I would kick off a little batch file to mount the tray drive (which was encrypted) and run SyncBack Pro to mirror the encrypted source. Then dismount.

I just bought a few extra trays. Each month I sync all the other HDD in the system (including the encrypted drive) for my off-site backup. One flaw in my system was if one of the other "data drives" crashed, I would loose at most a month of changes. They were just music/videos and didn't change very much. I accepted this fault.

I out grew the tower and recently built a cheap unRaid box. Most if it should work the same, except now I have redundancy for all my drives in the case of a crash.
