Deluge of Data Threatens Many Backup Systems
Approximate Volume of Backup Data
Over half of the respondents are trying to back up more than 100TB of data. 501TB to 1PB: 27%, 101TB to 500TB: 25%, 51TB to 100TB: 12%, 26TB to 50TB: 9%, 11TB to 25TB: 13%, Less than 10TB: 14%
Backup Technologies Currently in Use
Despite the availability of inexpensive disks, there’s still a lot of reliance on tape. Mix of disk and tape: 27%, Virtual tape: 26%, Physical tape: 18%, Integrated backup and archive: 9%, NetBackup OST: 9%, Other: 6%
Most Used Backup Application Vendor
Usage of Symantec products spans three different product lines. Symantec: 31%, CommVault: 18%, IBM Tivoli: 14%, Multiple backup applications: 12%, EMC: 9%, Other: 17%
Protocol Used to Backup Data
Given the volume of data involved, a lot of respondents use Fibre Channel for performance. Mix of Fibre Channel, NAS and Ethernet: 33%, Mix of Fibre Channel and Ethernet: 23%, Ethernet only: 16%, Mix of NAS and Ethernet: 10%, NAS only: 7%, Other: 11%
Current Disaster Recovery Strategy
Surprisingly, there is very little usage of cloud computing for disaster and recovery. Active-passive disk: 32%, Physical tape stored offsite: 21%, Active-active disk: 17% , Disaster recovery strategy in development: 13%, No disaster recovery strategy: 8%, Other: 9%
Backup of Encrypted Data at Rest
Just over half are now backing up encrypted data. No: 51%, Yes: 49%
Biggest Data Backup Challenges
The volume of data that needs to be backed up keeps growing exponentially. Meeting backup windows is more difficult each year: 70%, Consolidating backups would save significant cost: 69%, Currently not meeting backup requirements: 47%, Too many backup targets: 41%
Rate of Data Growth
Two in 10 respondents report that they are seeing data growth rates of 20% or more. Explosive growth (more than 24 percent): 6%, Rapid growth (20 to 24 percent): 15%, Significant growth (16 to 20 percent): 25%, Moderate growth (11 to 15 percent): 28%, Slow growth (6 to 10 percent): 23%, No growth: 3%
Database Duplication Effect on Controlling Costs
Not all classes of data deduplicate equally well. Having an effect: 44%, No effect: 32%, No deduplication: 24%
Number of Backup Target Environments
Each target backup system winds up increasing the total cost of backup and recovery. More than ten: 32%, Nine to ten: 4%, Seven to eight: 7%, Five to six: 13%, Three to Four: 27%, One to Two: 17%
