If the service account used with restic does not have the storage.buckets.get permission (in the "Storage Admin" role), Create cannot use Get to determine if the bucket is accessible. Rather than always trying to create the bucket on Get error, gracefully fall back to assuming the bucket is accessible. If it is, restic init will complete successfully. If it is not, it will fail on a later call. Here is what init looks like now in different cases. Service account without "Storage Admin": Bucket exists and is accessible (this is the case that didn't work before): $ ./restic init -r gs:this-bucket-does-exist:/ enter password for new backend: enter password again: created restic backend c02e2edb67 at gs:this-bucket-does-exist:/ Please note that knowledge of your password is required to access the repository. Losing your password means that your data is irrecoverably lost. Bucket exists but is not accessible: $ ./restic init -r gs:this-bucket-does-exist:/ enter password for new backend: enter password again: create key in backend at gs:this-bucket-does-exist:/ failed: service.Objects.Insert: googleapi: Error 403: my-service-account@myproject.iam.gserviceaccount.com does not have storage.objects.create access to object this-bucket-exists/keys/0fa714e695c8ecd58cb467cdeb04d36f3b710f883496a90f23cae0315daf0b93., forbidden Bucket does not exist: $ ./restic init -r gs:this-bucket-does-not-exist:/ create backend at gs:this-bucket-does-not-exist:/ failed: service.Buckets.Insert: googleapi: Error 403: my-service-account@myproject.iam.gserviceaccount.com does not have storage.buckets.create access to bucket this-bucket-does-not-exist., forbidden Service account with "Storage Admin": Bucket exists and is accessible: Same Bucket exists but is not accessible: Same. Previously this would fail when Create tried to create the bucket. Now it fails when trying to create the keys. Bucket does not exist: $ ./restic init -r gs:this-bucket-does-not-exist:/ enter password for new backend: enter password again: created restic backend c3c48b481d at gs:this-bucket-does-not-exist:/ Please note that knowledge of your password is required to access the repository.
