I tried the app and I did notice the first screen is "Select Storage Location" after you try to add a new backup and it lists: local dir, aws, gc, azure, b2, s3, sftp.

So I indeed guess it can as well be used as restic frontend (but I am not really sure to what extent it uses restic and whether blobbackup is just a gui/skin for restic)
