Q. Can I access the lower files while eCryptfs is mounted?
Accessing the lower files during an active eCryptfs mount is somewhat like accessing a block device on which ext3 is mounted. The kernel allows it, and it may work (depending on what you do with the data), but it is not a good idea.
Thanks for this. (I'd read it, but not understood it.)
I tried this, but get `device is busy' messages.
I don't understand why moving or copying the files is difficult. The manpage says, right at the start,
eCryptfs stores cryptographic metadata in the header of each file written, so that encrypted files can be copied between hosts;
so surely it ought to be easy to do?
I also tried mount --move /mnt/backup/secret /home/myname/Dropbox
This shifted the dir tree, but not the files, to Dropbox and made inaccessible the usual contents of Dropbox.
Maybe I should try sshfs as suggested above, or set up a vpn server on my home machine. What
I want to be able to do is the following: I use two desktops, home and office, a heavy laptop, a tablet, plus other desktops when I travel abroad. My Dropbox has about 30GB of stuff which can safely be kept in plain. I have another few GB of private stuff which I need to be able to get at, and edit, while away from the home machine. ecryptfs seemed like a good solution ...
