Data Loss Statistics
The following statistics were gathered from various sources:
- 6% of all PCs will suffer an episode of data loss in any given year. Given the number of PCs used in US businesses in 1998, that translates to approximately 4.6 million data loss episodes. At a conservative estimate, data loss cost US businesses $11.8 billion in 1998. (The Cost Of Lost Data, David M. Smith)
- 30% of all businesses that have a major fire go out of business within a year. 70% fail within five years. (Home Office Computing Magazine)
- 31% of PC users have lost all of their files due to events beyond their control.
- 34% of companies fail to test their tape backups, and of those that do, 77% have found tape back-up failures.
- 60% of companies that lose their data will shut down within 6 months of the disaster.
- 93% of companies that lost their data center for 10 days or more due to a disaster filed for bankruptcy within one year of the disaster. 50% of businesses that found themselves without data management for this same time period filed for bankruptcy immediately. (National Archives & Records Administration in Washington)
- American business lost more than $7.6 billion as a result of viruses during first six months of 1999. (Research by Computer Economics)
- Companies that aren’t able to resume operations within ten days (of a disaster hit) are not likely to survive. (Strategic Research Institute)
- Every week 140,000 hard drives crash in the United States. (Mozy Online Backup)
- Simple drive recovery can cost upwards of $7,500 and success is not guaranteed.
Although these figures are from an American survey, the results are likely to apply equally around the world. Remember that backups are essential, but unless tested they are an unknown quantity.
