 * `SYNC_SRC` source location for `rclone sync` command
 * `SYNC_DEST` destination location for `rclone sync` command
 * `CRON` crontab schedule `0 0 * * *` to perform sync every midnight
 * `CRON_ABORT` crontab schedule `0 6 * * *` to abort sync at 6am
 * `FORCE_SYNC` set variable to perform a sync upon boot
 * `CHECK_URL` [healthchecks.io](https://healthchecks.io) url or similar cron monitoring to perform a `GET` after a successful sync
+*  `FAIL_URL` Fail URL to perform a `GET` after unsuccesful execution. Default: `CHECK_URL` with appended "/fail" at the end
 * `SYNC_OPTS` additional options for `rclone sync` command. Defaults to `-v`
