-# this makes systemd OnSuccess OnFailure not behaving as one might expect

+# Kopia does not interrupts its run with an error exit code if a target or a repository are missing.
+# This hides errors and  makes systemd OnFailure event ineffective.
+# Below are the checks for the paths existence,

+# They are at the end because some backup might still get done even if something is missing
+# We just want exit code 1 to let systemd know there was a failure.
