I believe the most common usage of Duplicati is to utilize the built-in scheduler. So if a backup runs every 4 hours, for example, there is no interaction with the user to prompt for a description.
Or would it only prompt at the start of a manual backup?
Or do you just want the ability to apply labels on past backups that have already occurred?
My suggestion, the addition of a brief description may be useful when making copies in manual or automatic mode, but with a label. Example:
Automatic backup (system partition label)
Manual backup (SQL database label)
Manual backup (SQL 2 database label)
Manual backup (SQL 3 database label)
Automatic backup (label Complete database) and other options.
And then I will be able to understand for myself what is in these versions, it allows you to quickly make a decision.
Yep, I understand that… I just don’t know how these would be labeled in practice. Automatic backups are automatic, it wouldn’t be able to prompt you to input information on that backup version.
I can see it maybe being an option for manual backups.
You could provide a Setting like Put the date and Time and/or the Number of Files (changed) in the description or getting it from a file maintained by an external application.
