My Time Machine backup (6 TB USB-HDD) contains the data from my Mac's internal hard drive (2 TB) and from an external hard drive (USB 4 TB, Mac OS Extended, FileVault Encrypted) that I always keep attached.
Somehow my external 4 TB HD got corrupted and I need to reformat it. I want it Mac OS Extended, Encrypted, just as it was.
What is the right way to restore all the files from my Time Machine Backup so that Time Machine sees the hard drive as it was?
I had a similar problem before. Restoring the root folder of the HD with Time Machine was no problem, but Time Machine recognized the new formatted hard drive as a new one, resulting in a unnecessary new full backup of the HD, filling up my backup volume.
