Backup space

Managed servers

If you have our managed hosting service, then 50GB of backup space is included, and we will install and configure our backup script.

Caution

Our backup script takes a daily snapshot of all your filesystems. This kind of backup makes efficient use of our high performance always-online, offsite-mirrored backup space, and allows us to restore your service rapidly in the case of disaster. Please note, though, that we don't keep any historical backups. So if you delete a vital file, or your website is defaced, those changes will be copied to the backup space within 24 hours. This script is part of a backup regime, but not a complete solution.

Other servers

If you have ordered backup space, authentication is via ssh protocol. Many systems can then be used on top of ssh, such as scp, sftp, rsync, sshfs, or git. You will need an ssh key to authenticate which must be uploaded to the control panel backup page before you can access the backup space.

Using our script

If you want to use our backup script, you're welcome to do so. Please read the Caution above.

On Debian or Ubuntu servers, you can install mythic-backup from our repository:

wget -qO- http://mirror.mythic-beasts.com/mythic/support@mythic-beasts.com.gpg.key | apt-key add -
echo deb http://mirror.mythic-beasts.com/mythic mythic main > /etc/apt/sources.list.d/mythic-beasts.list
apt-get update
apt-get install mythic-backup

We also have a yum repository, for CentOS and RedHat servers. (Details to follow.)

After installing, you'll need to set CUSTOMER=backup-username in /etc/mythic/backup.conf, and copy the ssh key from /root/.ssh/id_mythic_backup_rsa.pub to the control panel backup page.

Manual backups

If you don't want to use our backup script, then you can roll your own backups using for example scp or rsync. Our backup server is backup-1.mythic-beasts.com, and your username is the name of your backup space, usually the same as the short name of your server. If your backup space is called foo, you can log into the backup server with this command:

ssh foo@backup-1.mythic-beasts.com

To copy a file to the backup server, using scp:

scp my_backup.tar.gz foo@backup-1.mythic-beasts.com:

You could also use rsync:

rsync -a --numeric-ids --rsh="ssh -T -a -oPasswordAuthentication=no -i/root/.ssh/id_mythic_backup_rsa" --rsync-path="rsync --fake-super --numeric-ids" /home/foo/Documents foo@backup-1.mythic-beasts.com:

In this example we are using the --fake-super option to store permissions in the extended attributes of the file system. This allows you to store full uid, gid, and permission information along with all your files, without requiring root access to the backup server.

If you make your own backups, please make sure that you know how to restore from them!
