You need to figure out what's wrong. There are two disks involved, the original library and the backup. There are two "databases" involved, the one kept by the OS file system and the one kept by J River. You will have to figure out where things went wrong. In the end you will have to delete duplicate files and leave the non-duplicate files, and this will involve deleting lots of files. However, if you screw this up then you will delete files that you didn't mean to delete and end up having to rerip (or give up). So the first step is to understand exactly what the state of affairs is. I suggest simplifying the diagnostic process:
1. Dismount and disconnect your backup disk. Restart the operating system. This will ensure that you aren't confused by your failed backup.
2. Use the operating system file manager to check your music library folder structure and see where files are located, especially duplicate files. You can look at the file names and you can also play these files directly using players that are not driven by databases. Use Foobar2000 rather than Jriver. It is likely that any duplicates will show a new creation date (after the date of your ill-starred backup). You can use the file manager to search for files created after some point and find all the newly created duplicates. You can then search for file names and verify that these are really duplicates, and not somehow moved copies of the original. (When a file is copied, the creation time is usually set to the time of making the copy, but the file mondification time is set to the time the file contents themselves were last modified, e.g. the time the rip was made.)
3. Make a new backup copy of your entire music library on a new disk drive. Hopefully, this step won't be necessary. It's to provide extra protection from "cockpit error". Based on your results to date, "cockpit error" is a likely source of your problems. To fix your problem you will need to delete and/or move files around and given the number of files involved there are many opportunities to make mistakes. (Been there, done that.)
4. Now go through your list of duplicates and verify that they are actually duplicates and delete them.
5. At this point you should be able to regenerate the J River index for your library. Then verify that you have all of the albums without duplicates. If some are missing you will have to track them down, this may involve remounting your problem backup, mounting the backup from step 3, etc...
If you are lucky and you aren't missing any files, then you are not yet done. You need to try and figure out what went wrong with your problem backup process before using this process again and getting disastrous results.
