Hardware Virtualization Disaster Recovery
A disaster recovery (DR) plan is good business practice for a hardware virtualization platform solution. DR of a virtualization environment can ensure high rate of availability during a wide range of situations that disrupt normal business operations. Continued operations of VMs is mission critical and a DR can compensate for concerns of hardware performance and maintenance requirements. A hardware virtualization DR environment will involve hardware and software protection solutions based on business continuity needs.
Hardware virtualization DR methods:
- Tape backup for software data long-term archival needs
- This common method can be used to store data offsite but can be a difficult and lengthy process to recover your data. Tape backup data is only as good as the latest copy stored. Tape backup methods will require a backup device and ongoing storage material.
- Whole-file and application replication
- The implementation of this method will require control software and storage capacity for application and data file storage replication typically on the same site. The data is replicated on a different disk partition or separate disk device and can be a scheduled activity for most servers and is implemented more for database-type applications.
- Hardware and software redundancy
- This solution provides the highest level of disaster recovery protection for a hardware virtualization solutions providing duplicate hardware and software replication in two distinct geographic areas.

Famous quotes containing the words hardware, disaster and/or recovery:
“A friend of mine spoke of books that are dedicated like this: “To my wife, by whose helpful criticism ...” and so on. He said the dedication should really read: “To my wife. If it had not been for her continual criticism and persistent nagging doubt as to my ability, this book would have appeared in Harper’s instead of The Hardware Age.””
—Brenda Ueland (1891–1985)
“It was so long since I’d seen masses of young men that I’d forgotten how much pleasanter men of between twenty and thirty were to be around with than older men. It isnt so true of women. When I was in my twenties I thought the grown adults I ran into were a disaster and now I know I was right.”
—John Dos Passos (1896–1970)
“With any recovery from morbidity there must go a certain healthy humiliation.”
—Gilbert Keith Chesterton (1874–1936)
