I have a good price and fast upload with a local online back-up provider. I like their service and only really have one complaint: they don’t encrypt my data client-side before transmitting it to their services.
Is there a good way, on the Mac, to encrypt my files before they are uploaded to the back-up provider? My data set is quite large, so copying all the files into a second encrypted location (encrypted disk image or similar) is impractical.
The back-up provider monitors the folders I have specified as back-up folders, and transmit any file changes in them.
