Data Replication for Disaster Recovery
All Upsolver data resides in your AWS account S3 buckets, in order to comply with cross region disaster recovery, you should enable data replication to a different region S3 bucket.
When a disaster occurs, you should change your Upsolver S3 connection bucket names and regions to the replicated bucket names and regions.
