STACK is a cloud storage solution provided by the Dutch hosting company TransIP. With a free account you can store up to 1000 GB, which makes it a great solution for use as backend in Duplicati.
STACK is available only for Dutch and Belgium users.
STACK supports WebDAV (in fact it’s a customized version of OwnCloud), what can be used to configure Duplicati.
This How-to describes the basic steps to configure Duplicati for making backups to STACK.
If you do not have a stack account, request an invite at https://www.transip.nl/stack/.
(NOTE: The service is targeted to Dutch and Belgium users. Requests from other countries will be refused).
When your request is acknowledged, you will get an email with instructions for setting up your STACK account.
(Optional, but recommended)
Create a STACK subaccount for your backups to separate Duplicati backup volumes from your regular files that you want to store/share in your STACK.
(Optional, but recommended)
Create a new folder or folder structure in your STACK, using your subaccount if you created one in step 2.
In the Duplicati Web UI, add a new backup.
Choose WebDAV as the storage type.
Use these settings for your backup job:
Use SSL: Selected
Server and port: youraccountname.stackstorage.com
Replace youraccountname with the name of your STACK account.
Path on server: remote.php/webdav/Foldername/Subfoldername
If you created a folder Backup with a subfolder MyPC, the path will be remote.php/webdav/Backup/MyPC
Username and Password: The name and password of the subaccount you created in step 2. If you didn’t create a subaccount, use the main username and password of your STACK account.
It’s worth mentioning that in order to set up an account with them, you need an address in the Netherlands or Belgium. If you don’t have that, you’re wasting your time…
But still: you are being quite tentative about this:
The only way I was able to even get an invitation was by using a VPN. Otherwise you get refused straight away.
When your request is acknowledged, you still need to enter your address and if that is not from the designated countries, it won’t work. Maybe that selection mechanism wasn’t actually intended because when I entered Sweden as my country, the form simply didn’t work. It was not possible to enter an address. Either way, I think it’s fair to say: it won’t work. Not: it might not work.
Please note that TransIP has announced that the free 1 terabyte storage plan will be discontinued in the next months and that all accounts that were not converted to a paid account will be deleted, including all stored data. More information in this post.
