Ask the Expert
Q.
How can data deduplication and replication help organizations with their disaster recovery strategy?
A.
In a virtualized environment, virtual machine (VM) images can be de- duplicated to minimize capacity requirements. The files that make up VM images are highly reducible. As multiple copies of a VM are stored, capacity requirements can be cut by 90% or more. Once images have been stored, they can be replicated to a remote location for disaster recovery. In addition to replication for offsite disaster recovery, files can also be copied to physical tape. Replication enables simple, secure offsite storage of images for disaster recovery.
Q.
Can data deduplication contribute to green IT efforts?
A.
Yes, data deduplication technology can significantly improve storage efficiency, which can lead to a reduced footprint in the data center. Through data deduplication, organizations can store the same amount of information with much smaller storage system requirements, and that means reduced power and cooling needs and lower overall costs. Another way data deduplication can contribute to green efforts is by helping to reduce the need for transporting tapes from one location to another.
