A full back up of an OJS or OCS installation should include three components: the OJS
system files; the files/ directory you created on installation; and
the database. There are many ways to make backups of these three components. Depending on
the tools at your disposal you may be able to make backups entirely over the web via an
administrative interface such as CPanel; or you may have to make backups via the command
line. The following section demonstrates one way to back up files via the command
line.
All servers are different, and the backup process in your case may be different than
what follows. If any of this confuses you or for some reason does not work, be sure to
check the documentation that comes with OJS in the docs/ folder, as
well as the support forum and
FAQ. But also be sure to read your service provider and server documentation
as well.
