My RAID back up took a dump so I'm redoing a complete library backup. (It a long story as to why it took a dump, let's just say I screwed up and it's no longer available)

But... I've been having a problem with power supplies and one of my two TwinStores I can't seem to get fired up.

So after backing up the first TwinStore to a "TwinStore Backup #1" Folder, I put the drives from the second TwinStore into the first TwinStore and created a "TwinStore Backup #2 Folder.

So my media is backed up to two different folders.

I am switching my library from the 2 TwinStores to a QNAP NAS.

My question is how to I combine the two backups when I run the Restore Wizard to migrate the two backups to the QNAP NAS?

Any help is appreciated.
Thanks in advance.
