S3 Offsite Multi Location #263

Description

@lcava000

Description

It would be great to have a multi-location/offsite replication system for S3 storage backends.

For example, the ability to configure multiple destinations such as:

  • S3-Hetzner-anylocation
  • S3-AWS-anylocation

This would allow data redundancy across different storage providers and infrastructures.

Use Case

I know this might sound unnecessary for providers like AWS, considering their advertised durability of 99.999999999%, but there are many real-world scenarios where this feature would be extremely useful — especially for self-hosted or on-premise environments.

For instance:

  • Keeping an additional copy on a self-hosted MiniIO cluster
  • Hybrid cloud + on-prem backups
  • Cross-provider disaster recovery
  • Protection against account lockouts, regional outages, or provider-side incidents

It would also be fantastic to support offsite copies over SFTP/FTP (if technically feasible).

This could be especially useful for older NAS systems or environments that do not support S3/Object Storage natively, such as legacy QNAP setups or traditional storage appliances.

Even if performance is lower, having a simple asynchronous replication/sync mechanism toward SFTP/FTP destinations could significantly improve compatibility and backup flexibility.
