Regarding the backup naming what you did is correct. Please keep in mind that using Akeeba Backup for Joomla to backup other sites should only be done when the other sites are also Joomla. If you have any WordPress sites there it's best if you install Akeeba Backup for WordPress on them. Otherwise they will only be possible to restore on the same server and add-on domain you backed them up from.

Regarding full backup testing, yes, it is possible. The way to test that is to automatically restore the site on a server and run some automated tests on select pages, making sure they include some text which would mean that the site is restored correctly.

If you're open to paying money for that, BackupMonkey does exactly that actually using our tools in the way that I'm about to explain below. Please note that BackupMonkey is not affiliated with Akeeba Ltd in any way and we do not get any kind of commission or compensation when you use their services.

Otherwise you need to write your own automation. Akeeba UNiTE can handle automatic site restoration and, as I said, it's what these other guys are using for their service. You can then either use something as simple as cURL piping to grep or something as powerful as Selenium to check if select URLs on the restored site contain the expected text. Any failure in restoration or the text tests will tell you that something's gone wrong with the backup.

I just want to clarify an assumption I made. When you say “add-on domains” I understand that you mean separate, full installations of WordPress in different directories, one for each add-on domain. In this case, yes, you need to install Akeeba Backup for WordPress on each different domain. Testing the backups means restoring each individual backup by itself and making sure it works. As far as Akeeba Backup and the process of restoring and testing sites go there is no difference to single site backup.

Another way to implement this is with a single WordPress multi-site installation where instead of sub-directory / sub-domain access for each blog in the network you’ve set up its own domain. In this case you do NOT need to (and really can not) install Akeeba Backup on each different blog on the network since Akeeba Backup for WordPress is only accessible from the Network Administration panel. In this case backing up your sites backs up everything. Restoring it to a set of different domains is possible and tested (it’s part of our automated WordPress restoration tests). In this case, however, you need to either use a live server with multiple (sub)domains attached to it or set up your local server to respond to multiple domains. Both of these are outside the scope of our support.

If you mean something completely different please clarify.

You're welcome!
