Take the 2-minute tour ×  I have a TrueCrypt file container in
the Google Drive folder. I add stuff into it, make sure
TrueCrypt changed the timestamp of the container. Google Drive
syncs with the server, but it seems it transfers the whole file
instead of the bit which is changed in the TrueCrypt container.
Would you know how to make it only sync the changed bit of the
container instead of 5GB every time?  share|improve this
question A loopback device, such as an encrypted container with
a static size, is the wrong solution for this kind of situation.
It works for Dropbox users due to their use of differentials.
But the right solution would be to use an encyrpted filesystem,
such as encFS. This was even suggested by a Google engineer,
Tyler McHenry. –  brianbaligad May 2 '12 at 7:39  3 Answers 3
