+.Sh BACKUP FILES
+Backup files have a '~' character appended to the file name and
+are created in the current working directory by default.
+Whether to create backup files or not can be toggled with the
+make-backup-file command.
+The backup file location can either be in the current
+working directory, or all backups can be moved to a '~/.mg.d' directory
+where files retain their path name to retain uniqueness.
+Use the backup-to-home-directory to alternate between these two locations.
+Further, if any application creates backup files in the TMPDIR,
+these can be left with the leave-tmpdir-backups command.
