SuperDuper! and copying Time Machine drives

[camner]

Thanks for the quick reply.

I think of SD! with my weekly (rotating for a month) full system cloning as my "backup" in terms of recovering from things like disk failure, system updates that went wonky, etc.

I then think of Time Machine as serving two purposes:

1. In between SD! clones to recover from, if needed
2. Archiving deleted files and previous versions of files

(And then I have a cloud backup for "house burns down")

What do you suggest for archiving purposes if it isn't TM?

And, if TM isn't for the purpose, what role do you feel TM plays in a backup strategy where SD! is used regularly?
