I'm going to format my iMac today and I've just backed up to an external drive using Time Machine.
But I am using encrypted backup, so Time Machine needs to encrypt the whole drive (after it has backed up). Right now, it says "Encrypting.... 35%". So it will take a long time.
Can I safely format now and still use the Time Machine backup, even though it's not fully encrypted? I mean, will it work the same way as if it was encrypted?
