Currently we have below architecture in the configuration, we can achieve HA for below levels except S3 to store the snapshots.

Load balancer
ops manager apps servers
ops manager app db
ops manager oplog store
ops manager metadata store.
s3(to store the snapshots)

We are currently using DC1 for storing the backups in s3 (in single region),
we would like to replicate the backups to a DR region and expecting ops manager to use the snapshots from DR region and restore in case of DC1 disaster.
However it seems the metadata can only read the snapshots from the DC1 S3 BUCKET.
And even if we copy/replicate the snapshots from DC1 to DR region ops manager cant use them from DR region since no metadata available in the metadata store or the existing metadata is not useful to restore from the DR region.

What would you like to see happen?

If the metadata available in the metadata store (in ourcase its a replicaset s3m-prod1) can read the snapshots/usefull to read from the DR region we can achieve the HA for backups.
And as we know both the s3 buckets should be in the ops manager configuration.

or if the ops manager can write the backups to more than one region that will help us in achieving the HA.

Why is this important to you or your team?

This is crucial for us ,since we manage hundreds of db's in ops manager , HA for backups is critical for us.

What steps, if any, are you taking today to manage this problem?

We do not have any alternative for now, currently using the available ops manager features.
Earlier we were using the filesystem, we faced many challenges there and migrated the backups to s3.
