Found How to backup the backup?, but wanted to poke at it from a different angle.
Most of the discussions in that thread cover doing a backup and then a sync, but what’s the argument for/against using Duplicati to back up Duplicati?
“Why would you do that, rather than just one duplicati with multiple destinations?”
So, suppose I have computers Dog, Cat, Hamster and Horse. All four back up across the local network to Horse-USB. Dog, Cat, and Hamster have only one daily backup set, nice and simple.
Horse, as well as having the backup set “Horse to Horse-USB” also has “Horse-USB to Wasabi”.
It seems administratively simpler to me – especially if I add complications like multiple backup sets from the individuals. (E.g. Dog has Dog-Critical, Dog-Important, and Dog-Nice-to-have, each with different cycles. They all go to Horse-USB, which gets backed up by Horse to Wasabi without any additional overhead. Otherwise I have to manage Dog-Critical to Horse, Dog-Critical to Wasabi, Dog-Important to Horse, Dog-important to Wasabi… etc.)
