One-quarter of our Storage magazine survey respondents use cloud backup, and are pleased enough to keep a big chunk of their backup data stored in the cloud.
Nearly 25% of our 244 respondents use cloud backup -- a fairly high number given the uneasiness about sending data offsite and the relative newness of this incarnation of cloud storage. Sixty-five percent of cloud backup users are very satisfied or satisfied with the services they’re using, and 49% expect to expand their use. Respondents send an average of 42% of their backups to the cloud and maintain an average of 12.6 TB of backup data in the ether. While touted as ideal for mobile user and remote-office backup, the heavy use case is for data center backup (58%). Users still rely on the service’s software for access (58%), but 47% use an in-house appliance or array to stage backups before they’re shipped to the service. The top reason for not using cloud backup: Nervous about sending data into a public cloud. The most recognized cloud backup services are Amazon (10%), Symantec (7%) and EMC (6%); Google, IBM, Iron Mountain and Microsoft were all at 5%.
“Works well for remote sales laptop users, but too expensive for data center backup due to the bandwidth required and the time to restore in a catastrophe.”
