Percona Backup for MongoDB (PBM) supports snapshot-based physical backups. This is made possible by the backup cursor functionality present in Percona Server for MongoDB.  In a previous post, we discussed Percona Backup for MongoDB and Disk Snapshots in Amazon AWS and showed how to implement EBS snapshot-based backups. Now, let’s see how to restore...
