It has been two days since I started Time Machine encrypting my external hard drive (6 TB in size.)
Why is it so slow? (disk connected via USB 3)
When I selected the disk for Time Machine, Time Machine itself formatted it to Mac OS Extended (journaled, encrypted). It then ran a successful backup, after that it encrypts the disk – what logic is that? Did it first write the files unencrypted, then it encrypts the files? Really?
