Dear All,
I am interested to know about folder encryption technology available
in Linux for remote backup purpose.
Let me clarify. I do my daily backup through ssh+rsync to a remote server.
It is quite fast because of rsync. On the remote box all the backups are
stored inside a folder. How can I encrypt that folder ? In that case,
I have to first decrypt the folder before doing rsync and then again encrypt.
Can I use any fuse based technology to achieve this ?
encfs+fuse is good but propt for the password, any option to provide password
through file ?
Any clue/suggestion is very much welcome.
Thanks

I backup on a remote folder through ssh+rsync and need encryption
on that remote folder. encfs+fuse is good but it prevents me as I
have not found to provide the password through a key-file yet.

Seems like there are several options to provide a pass-file.

If I type "encfs vs" into Google I get:
encfs vs truecrypt
encfs vs luks
However, does this the trick:
-S, --stdinpass
Read password from standard input.
OR from the file descriptor number in ENCFS_PASSWORD_FD
?

The --extpass or --stdinpass options for encfs can do this.

For example,
cat password-file | encfs --stdinpass encrypted-dir clear-dir

But it leaded to --stdinpass, the same result somebody else posted. So

if I post it it's bad and if somebody else does post the same it's ok?
Wow, what a funny list.
Ok now I know making a little harmless joke is forbidden and
brainstorming too.
Anything else forbidden or unwanted that's not written in the policy for
this list?

polkit issue, I shouldn't write about it, if somebody else with outdated
knowledge thinks he knows it better. Same for audio.
This list becomes more and more grotesque.
There's more noise about top posting, HTLM posting, bad hidden email
headers, not to do brainstorming, not to answer if you have more
knowledge, not making a joke etc., than about Debian Linux.
I nearly forgot too,
a newbie shouldn't ask newbie questions, but read what a smart question
is.
Anything else?

If enough people consider a problem such, it is easy to route around..
If one person consider another a problem, kill-file is a (partial?)
route around for them.
Perhaps debian-user_speak-yo...@lists.debian.org? :)
Shorter needed, so probably debian-user-uncensored@ldo
Would there be enough subscribers?
Would it dilute the assister pool?
Would _most_ assisters simply subscribe to both?
Would such a list be allowed within the policies etc of Debian? If
not, a non-Debian venue would be required, likely reducing the
visibility of such a list.
Would it be worth the experiment even though these questions can't be
answered definitively without running the experiment?
Regards
Zenaan
PS What is the difference between "Politically Correct", and "respect
for others"? Does an apology demonstrate respect? What about
non-acceptance of apology? Is it ok to be pro-$CONTROVERSIAL if $C..L
is [female|male|white|black|etc]?

rsync the encrypted files to the remote server.
