Yes, I know, but all the tools I tried, were interfering with my
normal workflow, while TM is unobtrusive enough to be tolerated.

Yes, a non-tested backup is about as valuable as no backup at all: you
keep on praying nothing happens, only this time the chances of
complete and catastrophic failure are reduced, not removed. TM is
different: it is not a bootable backup. It is a versioning backup,
that is understood by the system installer. Boot from the DVD, and you
can select to restore from a particular date.

Oh, sure, no disagreement from me there. But theory and practise often
diverge, and the reality is that before TM, I had an unreliable backup
method, and now I have a current backup.
