>I do backup to an external hard drive. But they say it is a good idea to have a back up outside of the place of work (for me my home office), just in case. I can backup to a USB drive and put it in the bank safe deposit but it would require frequent trips back and forth. This is why I thought that a back up to a cloud (maybe once a week) would not be a bad idea. I have not checked what is available and the cost yet. So it is just a thought.

Current external HD goes into on-premise safe. Whenever I go to one of the 2 banks where I rent safe deposit, that one goes into bank safe.
I keep 3 older HD versions in different places in the house, in case I miss out going to bank.
Main risks I try to guard against is stolen HW plus backup stolen as well, therefore redundancy on premise and 2 vaults.
Earthquake should not hit 3 different locations (on premise, 2 banks) that hard.
A-Bomb will probably kill me as well, as my lineage is not that close to cockroach, for the rest security is in redundancy ;-)

Newest data often goes to USB stick - but I distrust the crypto security of cloud services - even if owning physical HW, such centers are more luring targets...
