To accomplish this, use an old version of SuperDuper—specifically, v3.2.5<\/a>—to copy the Data volume, which is shown in the older version!<\/p>

v3.2.5 is well tested, having been on the market for quite some time, and is reliable. So we don’t have to worry about doing a broad beta test of a partially complete new release. It’s already tested, and I’ve been busy doing the additional testing necessary to prove it works on Big Sur.<\/p>

Again, this will make a copy of the data that you need to preserve your<\/strong> stuff, both Applications and Data, while leaving the Sealed System Volume alone.<\/p>

And it’s a valid source for “restore” during a clean install or migration! So restoration is easy<\/strong> and fast<\/strong> should it become necessary.<\/p>

M1 Macs can’t<\/strong> be copied in a way that makes them bootable. Bare metal recovery on an M1 Mac isn’t possible, since they depend on the contents of their internal drive even when booting externally. And the tools required to make bootable copies of Intel Macs are limited, often fail, and produce inscrutable and undocumented diagnostics when they do.<\/p><\/blockquote>\n\n
