This feature is only available in the Akeeba Backup Professional edition
Sometimes you may have accidentally deleted a backup record from the Manage Backups, or simply want to restore a backup file taken from another site. Normally, the only way to do that is to upload the archive file and Kickstart to your site and launch the restoration process from there. However, there are use cases where this may not be convenient, e.g. when you want to make a backup available for restoration by a non-technical client who can't reasonably use FTP. This is where Import Archives comes in.
This feature allows you to find archives stored anywhere on your hosting account and import them as backup records in Akeeba Backup, visible in its Manage Backups page. This means that you can upload backup archives anywhere in your site's folder structure, or even in a directory outside your site's root and Akeeba Backup will be able to import them. All backup archives are imported as backup records of the default backup profile (profile with ID #1) and can be restored just like any other backup archive.
In order to launch this feature, go to the Manage Backups page and click on thebutton in the toolbar. A new page appears which lets you select a directory. Alternatively, go to the Control Panel page and click on the button.
You also have the option to import archives from Amazon S3. Click thebutton directly above the directory selection box. It will take you to a slightly different page where you can enter the connection credentials to your S3 account and allow you to browse for ZIP, JPA or JPS files to import.
The "Import archives" page
Use thebutton to open an interactive folder browser in a modal dialog. Navigate to the directory which contains the uploaded backup archives and click on the Use button. The dialog closes and you can now click on the button to let Akeeba Backup search for backup archives inside that directory. You are presented with a new page, listing the discovered backup archives.
Importing discovered archives
Select the backup archive you want to import by clicking on them. If you want to select multiple files, Control-click (Windows, Linux) or Command-click (Mac OS X) the archive you want to import. After that, click on thebutton. After a short while Akeeba Backup takes you back to the Control Panel page with a message that the import operation completed successfully. You can now click on the Manage Backups (formerly "Administer Backup Files") button to view the newly imported backup archives. You can now download or restore the imported backup archives.
