I'm not entirely sure about the content you need me to work on, so I
conducted a full test. Here are the test steps, results, and logs:
Backed up the Linstor instance, which uses Linstor storage. The backup was
successful, with the backup name: linstor-2025-12-12T07:21:22+0000.
Created a new instance using this backup without specifying a storage
solution. The creation failed, with the following web information:

due to: Backup file for the volume [d22e4725-c83b-4fe8-a462-99dc5a40305b] does
not exist..
Created a new instance using this backup, specifying NFS storage. The
creation failed, with the following web information:
