I’m currently thinking about a backup concept for data stored in AWS S3. The data needs to stay in Germany, hence the eu-central-1 region. As it should cover natural desasers as well (e.g. a fire in Frankfurt), the backup may not be physically close stored.
I couldn’t find any data on where AWS Backup stores the backups. Are they stored in S3?
I know that every region has at least two "availability zones", but I couldn’t find clear information where the actual server centers are. Is it even possible to configure this for the S3 bucket / the backup?

It is stored across multiple availability zones, just like S3.
AWS Backups for S3 will be stored in S3, but you can configure it to be out-of-region. Be aware that these backups will not be point-in-time restorable
Depending on your use-case, it might make sense to take a look at an air gap solution like Clumio or Druva. You can store backups locally in a dedicated customer arena that’s isolated outside of your enterprise access controls. They also allow you to recover your data from an exact point in time.
