The average corporate turnover rate for employees is 15.1 percent across all industries, with some specific verticals experiencing as high as 30%. For an organization with 10,000 employees this can account for 1,500 to 3,000 people annually (Compensation Force: 2013 Turnover Rates by Industry).
When an employee leaves an organization the IT department will typically wipe or recycle their hard drive, containing their digital files and email, however, they neglect to clean and manage former employees’ data on corporate networks and servers.
For this scenario, a company of 10,000 looking at the conservative annual turnover of 1,500 employees, this could account for easily 60 TB of data that is abandoned in the data center each year. Over 10 years this explodes to beyond half a petabyte.
Abandoned data is unstructured files, email and other data owned by ex-employees that languishes on networks and servers. Gartner estimates that the 2013 average Annual Storage Cost per Raw TB of capacity is $3,212 (Gartner: IT Key Metrics Data 2014: Key Infrastructure Measures: Storage Analysis: Current Year, Dec. 2013). This can account for millions of wasted expenses each year.
Abandoned data consists of old working documents that have long outlived their business value: revisions of letters, old spreadsheets, presentations and aged email. However, a small percentage of this content can easily contain sensitive files and email. It is this small percentage of contracts, confidential email exchanges,
client records and other similar documents, which adds a level of risk and liability for the corporation.
The bulk of the data is typically what is known as redundant, outdated and trivial content – or ROT – that is simply taking up space and resulting in unnecessary management and data center costs.
The following are data factors to consider…
