PHYSICAL SERVER PROTECTION AND SECURITY
Backup and recovery architectures to restore critical data and applications to top level of priority in all organizations.
The factors in identifying low-hanging fruit for data-centre perspective is protecting VMs where important data resides.
Experts suggestion to look the importance of consideration to physical servers, Endpoints, and Security. Cost, performance manageability and even organizational politics can play a role in why physical servers are not in right way.

Host applications running on Linux and Windows VMs with hypervisors from VMWare, Microsoft’s Hyper-V for pooling and managing workloads and for creating multitenant cloud instances, but they are bundled in physical servers which are to be evaluated.
To prioritize the protection of server infrastructure along with VMs, the following to precaution can take.
· To recover a physical server where run critical applications and data, you can consider physical servers which are legacy systems spread throughout their organizations for migration to a SaaS offering or carry less priority or risk because they’re on a single system.
· Maintaining physical servers because some application is unable to run in a VM or the software vendor has prohibitive licensing terms that make running it on a physical server the only practical option.
· In cloud hosting category, many customers opt for dedicated long running thread for running their instances for extra spend.
· Performance and security are other factors.
· If you don’t give sufficient protection for physical servers along with OS or endpoints, then do backup correctly with enterprise backup solution and tools.
Consider when adding new physical servers and endpoints to your organization’s VM data protection architecture:
- Central Core management: Organizations that want to protect more number of endpoints, VMs and physical servers by building into Active Directory around organizational unit. Then you can profile your backup options.
- BACKUP Policy: In the context of backup, push out the backup installation via policy.
- Permissions: Enable administrators with central permissions of Organization Units for backup and restore functions.
- Incremental backup: CBT (change block tracking) to creating snapshots where only changed data is backed up to maximize performance. Consider backup solutions that provide snapshot CBT drivers for physical servers also.
- Storage target management: Central management to determine where backups are stored, whether it’s on a SAN, NAS, USB drive or the cloud. It is easy to recover physical servers and VMs collectively, which could prove important when a failure impacts both. It will also empower your helpdesk administrators to handle routine recovery issues as well.
- Storage efficiencies: Apart from CBT and data-deduplication other options include compression, Microsoft’s Resilient File System (ReFS) in Windows 2012 and above, which lets files share common logical clusters. Here ReFS offers block cloning, which creates copies of metadata instead of reading from and writing to the file data.
- Multiple backup targets: Having a centralized backup target provides a single place to recover. For primary data, it’s best to have at least three targets, in different locations and, if possible, at least one offline, to provide a layered defence. Make sure your backup and recovery solution can protect VMs, physical servers and endpoints as a failure in any one of these buckets can have a significant impact on your ability to recover quickly.
That gives organizations the opportunity to have a common approach in protecting physical servers, endpoints, and VMs.
