* * log `bool` True to log our actions (default: false)
* * maxrun `int` Only backup records older than this number of seconds will be reset (default: 180)
*
* Special considerations:
*
* * If global = true all backups from all origins are taken into account to determine which ones are stuck (over
* the maxrun threshold since their last database entry).
*
* * If global = false only backups from the current backup origin are taken into account.
*
* * If global = false AND the current origin is 'backend' all pending and idle backups with the 'backup' origin are
* considered stuck regardless of their age. In other words, maxrun is effectively set to 0. The idea is that only
* a single person, from a single browser, should be taking backend backups at a time. Resetting single origin
* backups is only ever meant to be called by the consumer when starting a backup.
*
* * Corollary to the above: starting a frontend, CLI or JSON API backup with the same backup profile DOES NOT reset
* a previously failed backup if the new backup starts less than 'maxrun' seconds since the last step of the
* failed backup started.
