+Enhancement: Improve handling of permanent backend errors
+
+When encountering errors in reading from or writing to storage backends,
+restic retries the failing operation up to nine times (for a total of ten
+attempts). It used to retry all backend operations, but now detects some
+permanent error conditions so it can report fatal errors earlier.
+
+Permanent failures include local disks being full and SSH connections
+dropping.
