Currently, I manage my assets in IMatch, with my DB, named "Personal Assets.imdb", and just now, made use of Pack & Go to back it up. It automatically assigned "IMatch_20210614.impag", as the name for the backup file, and I changed it to "Personal Assets.impag". Is this okay?
Do whatever you please. Pack and Do is NOT a backup tool. It is a tool to transfer IMatch settings and databases between computers. Package files are thus usually short-lived and their name is unimportant.
And, I'm not doing regular disk backups as well.
