+Bugfix: Never create invalid snapshots on backup interruption
+
+When canceling a backup run in the wrong moment it was possible that
+restic created a snapshot with an invalid "null" tree. This caused
+check and other operations to fail. The backup command now properly
+handles interruptions and never saves a snapshot in that case.
