When backing up on android the file is always named jex-export.jex. This causes android to always ask if I want to replace the previous file or cancel or keep both. Choosing keep both causes the backups to be numbered like jex-export_1.jex. If I move these to my backup drive, the count will begin from 1, which would cause problem when I move them again.
Backup name with date and time would make it easier to know when I backed-up last time by looking at the file explorer. Also the backups will sort themselves in order and there would be no conflict of filenames.
Something like: jex-export-20241102-193312.jex
