“Running a Linux image in the cloud means you have
access to implement whatever type of backup strategy you like. The
most simple, brute force method, is to create a volume of a few
hundred gigabytes, and simply copy files to it. You can also copy
disk images, database backup dumps, and anything else that falls
outside the traditional category of “file copy.“Many backup programs, especially open source ones, support
disk-based backups. You can simply point a backup program at a
remote volume with SSH access, and it will treat it as its backup
volume. If you’re implementing a quick-and-dirty backup solution
for the first time, tools like rsync are wonderful. Simply rsync a
directory every hour via a cron job, and it will copy only the data
that has changed. Many forms of rsync backup scripts exist, posted
to various Internet forums and newsgroups, ranging from simple to
extremely complex.”
