My question is really a two part one. First, I noticed there is a option to have your data encrypted when you first set up time machine on an external drive. Is this something everyone should do?
And what happens to my data, if I’m using file vault on my computer and encrypting my backups as well?
Does disk encryption and file vault degrade the quality of files like music and photos, as these items are continually being encrypted and unencrypted as I access them?
