The Import from URL feature can be used to import backup archives from external storage such as Dropbox, OneDrive and so on. The generic steps required are very simple:
Get a public URL to your backup archive
Use the Import from URL feature to import the backup archive
Below we'll see how to use this feature with Dropbox.
You don't need any third party software to import from Dropbox.
Log in to Dropbox' web site.
Navigate to the location of the backup archive.
Right click on the backup archive and select. Copy the URL shown in the pop-up dialog. IMPORTANT! The URL ends in ?dl=0. Change that to ?dl=1 before pasting it to Kickstart in the next step.
Run Kickstart and click on.
Paste the URL you copied in the URL to Import field and click on the button.
If you have a multipart backup archive repeat the steps 3, 4 and 5 for all parts (.jpa/.jps, .j01, .j02, ... or .zip, .z01, .z02, ...). This is important: if you're missing backup archive parts the restoration will not complete.
Go back to Kickstart's main page and begin the restoration of the backup archive.
It's much easier importing single part backup archives or backup archives with few parts. Since Akeeba Backup for Joomla! 4.0.0, Akeeba Solo 1.1.0 and Akeeba Backup for WordPress 1.1.0 you can use the Upload to Dropbox integration to upload up to 2Gb backup parts to Dropbox. Just make sure that the Enable chunk upload option is enabled in Akeeba Backup / Akeeba Solo.
You will have to follow a similar procedure. As long as you can get a publicly accessible HTTP/HTTPS URL for your files you can import them using Akeeba Kickstart's Import from URL feature. Make sure the URL you get results in the file being immediately downloaded, without showing you a web page that lets you download it. In the latter case Kickstart would download the web page, not the actual file. If unsure consult the documentation of the storage service you are using.
