replicate objects one at a time so as not to impede server load. Ideally, resync should not be initiated for multiple buckets simultaneously - progress of the syncing can be monitored by looking at `mc replicate resync status alias/bucket --remote-bucket <arn>`. In the event that resync operation failed to replicate some versions, they would be picked up by the healing mechanism in-built as part of the scanner. If the resync operation reports a failed status or in the event of a cluster restart while...

replicated objects to the DR cluster need to be re-replicated, `mc replicate resync start alias/bucket --remote-bucket <arn>` can be used to initiate a reset. This would initiate a re-sync between the two clusters by walking the bucket namespace and replicating eligible objects that satisfy the existing objects replication rule specified in the replication config. The status of the resync operation can be viewed with `mc replicate resync status alias/bucket --remote-bucket <arn>`.
