I need to do a partial restoration of a joomla backup that is done with Akeeba. That is: I need to restore and replace the files and db tables for one joomla component (com_mijoshop) from a backup I have.
Is there a way to do this with Akeeba? Thank you, Rajan Waitz

Yes, but not directly.

First restore the entire site on a server you run on your computer or a different domain.

Then create a new backup profile which excludes everything you'd like to NOT restore on the live site.

Take a new backup. This is a partial backup.

Restore the backup on your live server, using the same database connection information as the live site.

When you reach the Site Setup stage -- STOP. Close the window, delete the installation folder, kickstart.php and your partial backup archive from the site's root.

That's all there is to it.

Great, that sounds pretty straight forward. So just to be sure of the order: I restore the partial backup on top of my live site, so that I keep my live site, but renew (=overwrite parts of it) it with the partial backup, correct?

Thank you Nicholas

That is correct.

Restoring a backup will, by default, only add new or overwrite existing data from the backup. It will NOT remove any data on your site which doesn't exist in the backup. I was the stupid user who lost his data because he didn't pay attention to the defaults some 17 years ago. That's how I ended up being interested in backups and writing my own backup software :)

If you are unsure you can always do a local test – in fact, I recommend it. After you have your partial backup keep it to the side. Restore the latest full site backup on your local server. Now restore the partial backup on top. If you spot any problems you have missed something when making the partial backup.

This is the same process we use when launching major changes to our site, e.g. a site redesign, menu restructiring or a major upgrade to one of the extensions that power the site.
