restic - integrity checking

Its a very good idea to regularly check the integrity of your restic backups to hopefully find any problems before you have to use it to restore some files from backup. So this is my script called 'restic-check' which will run at 0100 from a cronjob. I know it works as I've tried it out before setting the cronjob.
