Planning for the worst case: the importance of a backup solution

A Backup Strategy should be an integral part of a healthy data system.

Computers and computer components can and will fail; multiple disk failures in RAID configurations, data center catastrophes (no matter how small) and virus infections can take down your system and corrupt critical data.

There is usually no warning before it’s too late. Suddenly data is unrecoverable and lost – and basically data loss can be costly and may impact productivity.

There is a large amount of investment into the data on a user hard drive. Some data value is obvious, such as company financial data or employee records, which would be disastrous to lose.

Consider the man-hours reinstalling the base software (operating system) on your computer and reconfiguring your environment to suit your preferences again. In some instances this could easily cost you several days of productivity. In extreme cases, some data may not be recoverable.

Implementing a backup plan will often turn several days of lost productivity and weeks of reorganizing into an hour of restoring your disk image.
Depending on the importance and value of your data, storing a regular backup securely off site may be prudent, in case of a disaster or catastrophe.

Redundancy provides the ability to survive the loss of a single hard drive, and replace the failed drive without a system crash. In theory this is good, but does not provide for data viability in the event of two drive failures, or two drive data corruption. DO NOT confuse hard drive redundancy with a true backup.
