I have a conundrum that I think can be solved with VEEAM backup and replication.
Is the proposed solution plausible?
1. I have two networks: one is Internet-facing, and the other is a closed network.
2. The virtual machines on the Internet side receive OS and third party application updates.
3. When the Internet-facing virtual machines (there are 40 VMs, each is approximately 40 GBs) have received updates I export the VMs to an external drive. The export takes approximately 17 hours.
4. After export, I WALK the disk to the closed network (that is the nature of my environment) and perform an import. The import script deletes the targeted VM and replaces it with the recently patched VM. The process takes another 17 hours or so.
1. Stand up two VEEAM Backup and Replication servers (one for the Internet-facing network, and the other on the closed network).
2. After the Internet-facing VMs have been updated, perform a backup.
3. After the backup, export the backup files and WALK them to the closed network.
4. Copy the backup files to the other VEEAM Backup and Replication server.
5. Execute a VEEAM job to copy only the deltas from the backup files to the closed network VMs. I am assuming this is much faster than deleting existing VMs and replacing them with recently patched VMs.
