SunGard Financial Services was experiencing backup woes in its highly virtualized environment. Using tape along with VMware Consolidated Backup (VCB) and Symantec Backup Exec was proving problematic.

"We didn't have enough tape bandwidth to complete large backups and were experiencing high rates of backup failure," said Guy Chapman, a senior engineer for storage and virtual infrastructure at SunGard Financial Services, who is based in London.

The company looked at various options as an alternative to tape, including storing data on SATA disks within a SAN. Eventually, however, it switched to EMC Data Domain for deduplication and Symantec NetBackup software. Some backup remains on tape, but much of it has switched to the Data Domain appliance.

"Data Domain-based deduplication worked out at about one fifth of the cost of SATA/SAN storage," said Chapman. "We have also reduced our backup and recovery costs per VM [virtual machine] by 10 times."

SunGard Financial Services is one of the four business units of SunGard. While SunGard Availability Services is perhaps better known due to its disaster recovery services, SunGard Financial Services is actually a larger revenue generator. It contributes more than 50 percent of the annual $5 billion-plus of SunGard by delivering software and IT services to institutions in virtually every segment of the financial services industry.
