Flexibility The faster, more efficient storage capabilities of disk drives let administrators schedule more frequent backups, lowering the exposure from any data loss. Disks used as backup devices can also support simultaneous backups, restores, and duplication operations. This is impossible with sequential tape drives.
Efficiency Disk-based backup´s ability to write multiple backup jobs simultaneously to individual backup files (one file per job) provides both exceptional performance and storage granularity that tape solutions cannot approach even with the most sophisticated multiplexing, multi-threaded solutions.
Expense Because disk-based backup increases the speed, flexibility, and efficiency of a data protection strategy, it also lowers the total cost of ownership of storage management.
Rapid system recovery
As important as data recovery is, it isn´t sufficient to help a business resume operations if there has been physical corruption of a system or application, or loss of a server. Rebuilding systems from bare metal can take hours or even days.
That´s because system recovery traditionally has been a very manual, intensive process. Steps include repairing the hardware and reinstalling the OS, applications, patches, system updates, and other system requirements. After these were completed, administrators would then need to try and reconfigure the system back to the exact state before the disaster. Several tests would be needed to ensure the system was ready for production. Then administrators would need to load the data onto the system from the last backup. Finally, the system would be introduced back into the live environment.
In contrast, today´s recovery solutions combine the speed and reliability of disk-based, bare-metal Windows system recovery with new technologies for hardware-independent restoration. This allows organizations to perform a full system recovery in just minutes, and to create real-time system recovery points without disrupting accessibility. Additionally, this delivers the flexibility to recover to dissimilar hardware. By removing the need to recover systems to the identical hardware where recovery points were created, this eliminates the cost of having to maintain duplicate hardware solely for the purposes of system recovery in the event of an emergency.
In addition, administrators can perform system restorations even if there´s no hardware available by restoring recovery points to virtual environments. When new hardware is available, or existing hardware is repaired, the servers can then be restored from a virtual machine back to a physical machine without impacting business continuity.
Traditionally, enterprises have struggled to recover whenever their IT operations were disrupted. All too often critical data and systems tools weren´t interoperable. IT operations and security functions overlapped or had conflicting priorities. And problems could require dozens of vendors to fix. The result has been higher costs, slower response times, and an inability to achieve business objectives.
Better and faster backup and recovery are required because IT downtime has become less predictable given all the dynamics that can affect IT today. As they increasingly expose their networks to customers, partners, and suppliers, enterprises must be able to isolate a threat or outage and know precisely what steps to take to recover.
By deploying both best-of-breed data protection and best-of-breed system recovery solutions, enterprises are in a better position to keep their business up, running, and growing, no matter what happens.
