GPG encrypted backups to rsync.net

Mon, 28 Nov 2016 21:02:25 +0000

I use rsync.net for my cloud/offline backups.

Here’s how to do gpg encrypted backups.

Mount rsync.net using sshfs and create a backup folder

1mkdir -p /home/your_user/rsync.net/
2sshfs 99999@server.rsync.net: /home/your_user/rsync.net/
3mkdir -p /home/your_user/rsync.net/backups/

Create and encript a directory

1tar --xattrs -czpvf /tmp/2016-11-28_my_dir.tgz -C /home/your_user/my_dir .
2gpg --cipher-algo aes256 -c -o /home/your_user/rsync.net/backups/2016-11-28_my_dir.tgz.gpg /tmp/2016-11-28_my_dir.tgz

Restore and decrypt a directory

1mkdir -p /tmp/extract
2cd /tmp/extract
3gpg -o- /tmp/2016-11-28_my_dir.tgz.gpg | tar zxvf -

Unmount rsync.net

1fusermount -u /home/your_user/rsync.net/

Backups using ecryptfs and rsync.net

I use rsync.net for my cloud/offline backups.

Here’s how to do encrypted backups using ecryptfs.

Install ecryptfs-utils

1sudo pacman -S ecryptfs-utils

Generate a passphrase

1ecryptfs-setup-private --nopwcheck --noautomount

Mount rsync.net using sshfs and create a backup folder

1mkdir -p /home/your_user/rsync.net/
2sshfs 99999@server.rsync.net: /home/your_user/rsync.net/
3mkdir -p /home/your_user/rsync.net/backups/

Mount the backups folder as an encrypted filesystem and copy some files

1sudo mount -t ecryptfs ~/.Private /home/your_user/rsync.net/backups -o key=passphrase,ecryptfs_cipher=aes,ecryptfs_key_bytes=24,ecryptfs_passthrough=n,ecryptfs_enable_filename_crypto=n

Unmount rsync.net and the encrypted filesystem mount

1sudo umount ~/Private
2fusermount -u /home/your_user/rsync.net/

rsync.net mysqlbackup.sh

Following up on my post about backing up mysql using rsync.net, I created a github repository to keep and improve the script.

It uses mysqlhotcopy and duplicity to backup mysql databases to rsync.net.

Stay tuned for the first milestone release.

Backing up MySQL in B3 Server to rsync.net

In a previous post I talked about how to backup to rsync.net using duplicity.

I will now show how to backup your B3 Server Mysql databases using the same method.

Installation

Be sure duplicity is installed:

1su
2apt-get install duplicity

Generate an ssh key to connect to rsync.net

Generate the ssh key using the defaults (don’t use a password when asked):

1ssh-keygen -t rsa

Copy your key to rsync.net (if you don’t have no one there):

1scp ~/.ssh/id_rsa.pub user@server.rsync.net:.ssh/authorized_keys

If you already have a key from another machine or user in rsyn.net, you need to add a new one:

1cat ~/.ssh/id_rsa.pub | ssh user@server.rsync.net 'dd of=.ssh/authorized_keys oflag=append conv=notrunc'

Generate a gpg public and private key to encrypt your backups

Generate the gpg keys (get down your private key, example: 123AbcH123BB4321):

1gpg --gen-key

You can check the keys in your system:

1gpg --list-keys

Look in the output something like this. Look for the public key (in this example your public key is 1AAB123A)

1pub 1239A/**1AAB123A** 2011-10-09 [expires: 2012-10-08]
2uid Your Name (name) <mail@mail.com>
3sub 54321/1234BBCC 2011-10-09 [expires: 2012-10-08]

Backup/restore your databases

I have MyISAM tables, so I will be using the mysqlhotcopy command. You can also use mysqldump.

Offsite backups with rsync.net

If you don’t do backups… well, you should.

An example of a good backup system could be:

External drive backups: your computer is backed up at an external drive;
CD/DVD backups: burn your backups to a CD or DVD;
Offsite backups: your backups are located at a different site, ie, another place other than your home or office.

A good idea is to have all three backup systems in place. External drivers can brake and DVDs are misplaced, so a offsite location for your backups are a good idea.
