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?

CodePudding user response：

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.
