Feature request - backups by hostname rather than IP

[ajcook7]

unimus-backup-exporter.sh. creates backups into a ./backup directory, then directories of the form '172.19.24.42 - 72'/ and finally "interestingly" formatted backup names such as 'Backup 172.19.77.154 2023-05-31-10:30:50-AEST 69.txt'.

While these are technically correct, the formatting and structure of the device backups are extremely difficult to work with in a CLI or scripting context, and very difficult to work with in an operational environment with hundreds of devices. We have DNS so we don't need to remember IP addresses, right? :)

What would be extremely helpful is having an option to use the device hostname rather than IP to identify directories and backups, in conjunction with removing spaces and dots from the naming structure of directories and filenames.
