A recent study suggests that a majority of enterprises continue to use tape libraries as backup data sets continue to grow.
That study, released by disk backup provider Sepaton Inc., reports that 57% of 168 enterprises surveyed are using backup tape libraries. The survey also noted that approximately 60% of enterprises use a mix of tape and disk-based backup, including those relying on solely tape archiving. About 44% of respondents reported using on-site snapshots or network-attached storage (NAS) filers, according to Sepaton. The number of respondents that reported having greater than 30% annual growth increased from 28% of respondents in 2010 to 33% of respondents in 2011. That additional volume requires more time and capacity to handle all that data, according to the survey, which noted that about a quarter of respondents need 24 hours to complete a full data backup.
The survey included 168 “enterprise companies,” which Sepaton defined as companies with at least 1,000 employees and at least 50 TB of data. The companies included representatives from several industries, including finance, manufacturing, healthcare and education.
Some other study highlights:
Approximately 34% of remote or branch office data is not backed up by large enterprises, while 87% of data center information is protected.
Fifty-three percent of respondents said disaster recovery testing is “minimal” or “not frequent enough,” while 47% of respondents to report that testing is conducted “well.”
