If you want to make quick encrypted remote backup of your data, the only things you need are bash, tar, gpg and ssh.
“tar” packs your data into a single stream of bytes, “gpg” encrypts the stream and “ssh” remotely stores the encrypted stream to chosen file.
tar cv folder_to_backup | gpg -e -r gpg_user_id | ssh remote.host "cat > folder_backup.tar.gpg"
Note – you don’t need to compress “tar” stream as “gpg” during encryption compresses data for you.
Recently Erlang Solutions have published a new version of esl-erlang debian package with the newest Erlang/OTP 20.0. This new major Erlang release contains a few incompatibilities with earlier versions for which we still need to update our software.
There is a simple way to temporarily prevent ‘apt-get upgrade’ from upgrading ‘esl-erlang’ package to the newest version – the only thing you need to do is to put this package on ‘hold’ with
apt-mark hold els-erlang.
Later on you use
apt-mark unhold esl-erlang to again allow debian package manager to upgrade this package.
