Nearly half the companies polled in our most recent cloud storage survey say they're using one or more cloud storage...
service providers to store an average of 24% of their total data.
While backup is still the most favored application for cloud storage with 63% of respondents saying at least some of the backup data goes to the cloud, other applications are gaining momentum as well: disaster recovery was cited by 44% of respondents, followed closely by collaboration/file sharing (41%), archiving (40%), primary storage (38%) and nearline storage (19%).
It's not so surprising that backup, DR, file sharing and archiving lead the list as each has been mentioned frequently as a potential cloud storage killer app. But with 38% indicating that they're also sending live, production primary data to the cloud, it could signal a shift in the perception of cloud storage and a greater level of comfort with cloud storage security.
That said, security was still cited more frequently (50%) as a concern related to cloud storage than any other factor. The cost of cloud storage loomed large, too, with capacity fees a concern of 32% of respondents, followed by transaction costs at 28%.
Still the sheer volume of data getting parked in the cloud is growing. Among our survey group, 31% said they had more than 25 TB in the cloud, with 8% telling us that they have more than 100 TB sitting on cloud storage.
