CCC 这意思是暂时无法从克隆盘启动了？

Update Nov 11: Apple addressed some of the APFS replication issues in the Big Sur 11.0.1 update, and CCC 5.1.23-b1 includes support for making bootable backups on Big Sur. This build is also a Universal Binary, so it will run natively on M1 Macs.
Apple 列出了 Big Sur 11.0.1 中 APFS 复制的一些问题，CCC 5.1.23-b1 支持在 Big Sur 中创建可启动的备份，因为是通用的二进制软件，所以可原生支持 M1 Mac,

Obviously we won't know if it will make a bootable backup of an M1 Mac yet, but we'll be sorting that out over the next few weeks during the CCC 5.1.23 beta cycle.
但是，我们限制还不知知道可启动备份能不能再 M1 Mac 上正常工作，未来几周（ 5.1.23 beta 开发周期) 我们会进行测试来确定是否可以正常运行。

To access the beta, go to CCC's Preferences > Software Update and check the box to be informed of beta releases, then click the button to check for updates. Please note that this does not change our advice on waiting for the upgrade, we think it's best practice to wait for some OS updates to come along before applying a major OS upgrade to a production Mac.
你可以通过通用-软件更新，勾选 beta release 来获得 beta 版本。请注意我们仍建议等待苹果发布若干更新后再对工作用机进行大版本的系统更新

APFS replication 应该译作 APFS 副本

ccc 和 tm 有啥区别？

@VZXE
ccc 之前可以全盘备份（带启动盘的那种）。
换言之，ccc 备份至移动硬盘后，该移动硬盘可在其他 Mac 上启动。

一直用 ccc，全盘备份可直接启动是我最需要的功能，希望之后能解决这个问题吧。
