Moving an existing checkpoint to external storage

🍱 Features & apps Backup
1

Hey all,

I have a first full backup checkpoint compressed, encrypted and packed. While it was in the packing step (which took a while), I added a SFTP external storage and configured the backup app to use it for checkpoints.
I was hoping the cronjob would take care of moving the file but something went wrong. A folder with the name of the checkpoint was created on the external storage, but it’s empty. EDIT: not completely empty in fact:

Looking at the logs this is what I see:

What’s wrong with my setup? My external storage is Hetzner storage box.

Thanks for your help.

I attempted to manually launch the upload:

After that, I tried removing the remote folder with the empty restoring-point.data to see if it would help, but now the point is “locked”.

# occ backup:point:upload 20230911051503-full-XouUx7Feg6jQZHh

In MetadataService.php line 155:
                   
  point is locked

I don’t really know what to do at this point. :frowning:
