Deluge of Data Threatens Many Backup Systems

When it comes to backup and recovery, IT organizations are clearly struggling with the amount of data that needs to be managed. A new survey of 200 IT professionals conducted by Sepaton, a provider of data protection systems, finds that more than half of the respondents are trying to back up over 100TB of data. Exacerbating the issue is the fact that IT organizations, in response to security concerns, are starting to encrypt more data, which makes the actual volume of data that needs to be backed up even larger than it would normally be. The end result, finds the Sepaton study, is that a lot of IT organizations are looking for backup and recovery systems capable of operating at significantly higher levels of performance. Not surprisingly, there are too many target systems that need to be managed. What may be surprising, however, is that despite all the hype about cloud computing, there is little reliance on the cloud to back up that data. Another survey aspect that may also disappoint some of the folks promoting the latest and greatest in backup storage technologies is how much reliance there still is on tape drives for backup. Despite all the known issues with recovery, it appears that the cost of tape as a backup medium is still too low to ignore.

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%
