Data loss in virtual environments impacts many organizations

80 percent of companies believe that storing data in a virtual environment decreases or simply does not impact their organization’s chance of data loss. Yet, 40 percent of companies leveraging virtual storage experienced a data loss from those environments in the last year, according to a Kroll Ontrack study.

The study, based on a survey conducted by Kroll Ontrack, also indicates that 84 percent of corporations are leveraging virtualization for storage, and nearly one-third of respondents have 75-100 percent of their current environment stored in a virtualized environment.

“It is a common misconception that virtual environments are inherently safer than, or at less risk from data loss, than other storage media,” said Paul Le Messurier, data recovery operations manager, Kroll Ontrack UK. “Although virtual servers have redundancies built-in, increased complexity generally means more potential causes of data loss, including file system corruption, deleted virtual machines, internal virtual disk corruption, RAID and other storage/server hardware failures, and deleted or corrupt files contained within virtualised storage systems. The effects are also usually far more serious because the volume of data stored in a virtual environment is exponential to that stored on a single physical server or storage device.”

Additionally, the survey found that only 33 percent of companies were able to recover 100 percent of their lost data, which represents a 21 percent decrease from 2011, when 54 percent were able to recover 100 percent of their data. The other 67 percent of respondents disclosed that they were not able to get all their data back from their most recent data loss event.

When asked about how organizations attempted recovery, the largest portion of respondents, 43 percent, actually rebuilt the data. Only one in four looked to a data recovery company.
