Simple way to make encrypted backup of data volume only

[jmsgwd]

Thanks for your reply.

I have a number of HHDs for backing up multiple Macs which I rotate - replacing them all with SSDs would be expensive.

OK I'll try using v3.2.5 to backup just the data volume to an encrypted but empty destination drive, and see if that works.

After giving it some thought, and contrary to what I said in my original post, I think my ideal backup process would probably include both system and data volume, to give at least the option of restoring the system without re-installing everything. But it would still be encrypted, and would not require booting from the backup and enabling FileVault. And I'm still fine with it not being bootable.

Do you think this might be possible in future versions of SuperDuper with macOS 11+ on Apple Silicon?
