Automatic warning for insufficient disk space for a new backup

I work with sites that have large media libraries, and backups basically double the disk usage of a site (until they’re uploaded to remote storage and then deleted locally).  As such, running out of disk space is a fairly common issue.

It would be great if UpdraftPlus could scan the amount of temporary disk space needed for a backup, check the available disk space at the start of a backup run, and then issue a warning or error if it determines there won’t be enough room to save the temporary files.
