Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can :heart:

Nextcloud version (eg, 18.0.2): 18.0.4
Operating system and version (eg, Ubuntu 20.04): Ubuntu 18.04.4

PHP version (eg, 7.1): 7.3.17

The issue you are facing:

I added an external storage to my Nextcloud instance which is linked to my Backblaze account/bucket. When I upload a file through Nextcloud into my External Storage folder, my Backblaze ‘Browse Files’ view shows the same file uploaded twice, meaning double the storage! I am able to view/access/download the file properly through both NC and BB, but I don’t want to have to store the file twice? Not sure if I set up the connection properly, but there aren’t too many places to get lost in there.
Please advise!


Is this the first time you’ve seen this error? (Y/N): N

Steps to replicate it:

  1. Set up a BackBlaze external storage account
  2. Upload a file to the BB storage folder through the NextCloud interface
  3. Notice that there are 2 versions of the file stored in the BB File Browser interface.
