So, if I have one-time erased-then-copied, unless there is a system update, I can then smart copy.
Except... if I want to create a schedule and then forget about it, I would be best off erasing-then-copying my MacintoshHD every time. Feature request? Could SD check if a given backup requires system files, and if there has been a system update,then SD would choose the appropriate backup? I am thinking that Apple must leave itself a message somewhere of the system status. |

No, you'd be better off scheduling a Smart Update. You can always add a system or just restore the data, but if a drive fails during an erase, you'd lose the backup.
And that's why we don't do what you're suggesting. Unlike Catalina and earlier, we cannot update "just" the system without wiping the entire backup. Doing so is more dangerous than NOT doing so.

OK. Thanks. For my purposes I think I will just schedule erase-then-copy because I make two different backups every night. If MacintoshHD or the backup disk fails during an erase-then-copy, I still have the other backup that was made using a different external HD. If Macintosh HD gets corrupted, I want a quick, bootable, backup with the latest OS update, just like in the old days.
I think that I have no idea of the magnitude of the headache that Apple has caused you with this process. |

I'm sorry, Dave. One more problem. I just finished erase-then-copy of a 2nd backup in the same container. The other one was already bootable. But... the new one does not sow up in the Startup Disk. Is there something else I need to know. The log file says:
| 09:57:05 AM | Info | ...ACTION: Making MWF 7 bootable | 09:57:06 AM | Info | ......COMMAND => Updating booter | 09:57:08 AM | Info | Successfully blessed macOS folder on /Volumes/MWF 7 |

Check in Option+Boot or Power+Boot.
