Agree with great comments from @Jojo-1000
“anything” is broad. It can’t get databases from old image restore because you updated them, right?
Your job database is on the Database screen. Your configuration for all jobs is Duplicati-server.sqlite. Locations vary sometimes (e.g. a Windows service is different). You can also sanity-check file dates.
It will get source files as always. For best continuity you should probably do Syncback before backup, however if you don’t then you’ll just get a Duplicati version whose files are three weeks too old awhile.
Duplicati expects the Source files to change. It has no way yet to protect itself against records reverts from restore of databases from an old image. so it’s important to keep job DB and destination aligned.
Migration to new PC - faq wanted has some other notes. Exporting a backup job configuration to a file (saving it somewhere secure) would be good practice to guard against server loss, but for this work it’s probably easier to put back all the latest configs by putting back the pre-Acronis Duplicati-server.sqlite.
