Welcome to the forum @Lymos
If you have the old computer and can copy the old Duplicati databases, that’d be the most accurate path:
Migration to new PC - faq wanted
If you no longer have it, then it’s good you have some essentials. The same post has a repair path here.
That repair should rebuild the job DB, and that’s enough for a restore, but backup config detail is missing.
If you have to figure out what old source paths were, you can guess from the backup while doing restore.
Hopefully you weren’t doing a lot of fancy path filters or other config that you’d have trouble remembering.
Direct restore from backup files, however that’s just the restore, and doesn’t set anything up for backups. Certainly a reasonable quick fix if you think the full database and configuration will take awhile to get back.
