Failure of traditional tape backup
Corporate backup strategies have been in place for a very long time. Under
a typical backup plan, a business may copy all corporate files to tape on a
daily basis, usually on off-business hours. Those tapes are then generally stored
in an offsite location on a weekly basis. When files need to be restored, the
correct tapes have to be located and loaded, and the actual file recovery can
be a lengthy process.
That old model is quickly changing for a variety of reasons:
Growth in corporate applications and the associated data. Businesses
increasingly rely on critical, growing applications with special needs, including:
- Rapid backup of applications and data-with minimal disruption to systems
or users
- Fast local and remote restoration of data to get "back online"
after a disruption
- A cost-effective backup/recovery platform flexible enough to scale up, scale
out, and be managed in-house or by an outside vendor as company needs grow
and change.
The evolution of a distributed workforce with the need for 24/7 system availability.
As the workforce has changed and workers have come to expect and depend upon
constant access to corporate data, two specific scenarios have required IT professionals
responsible for data protection to adapt their backup strategies:
- Traveling salespeople and professionals working from home
- Businesses with multiple locations
As companies add regional offices with limited access to dedicated IT staff,
centralized IT organizations look to technology alternatives to help them simplify,
automate and manage the protection of remote office data and to ensure that
each office has access to the same up-to-date files.
A stronger emphasis on disaster recovery. Business data needs to be
available at all times, even after a natural disaster or an act of terrorism.
The modern IT professional has responded by finding cost-effective, manageable
disaster recovery plans. Relying on data written to tapes in a warehouse is
simply not acceptable in a modern corporate environment.
Technology improvements. Advancements in disk storage capacity have
made disk backup an inexpensive, reliable, faster and more convenient strategy
than tape backup.
