See how Tata Power Delhi is reducing its database backup time and restoring critical data faster

Tata Power Delhi Distribution Limited (TPDDL), a subsidiary of Tata Group, recently transformed its power distribution business by implementing high-tech automated systems, including remote grid and outage management systems. Currently, the power utility provides electricity to seven million consumers in North and Northwest Delhi.

TPDDL used to store a large volume of consumer data on EMC’s LTO tape drives and then ship the tapes to an offsite location via a courier agency. It was time consuming and costly to transport tapes from one location to another and involved risk of data breach. To meet regulatory requirements and mitigate risk, TPDDL needed to adopt a disaster recovery solution that shortened its database backup and restoration time and reduced operating expenditure (OpEx).

“We adopted Oracle Database Backup Cloud Service because of its superior encryption and compression capabilities—features that vendors like Amazon, Nextra, and Rackspace could not offer. The solution also provided the unlimited scalability and high level of integration our business required,” says Amit Taneja, Manager, TPDDL.

Challenges

  • Improve the efficiency to backup a large volume of data for two critical applications—revenue collection and maintenance—and cut the electricity provider’s OpEx by automating database backup process instead of transporting up to 15 physical tapes daily to an offsite location
  • Ensure consumer data security and meet regulatory electrical requirements by enabling end-to-end data protection via the cloud rather than using tapes
  • Gain ability to quickly access and restore the database from a backup database at any time and from anywhere

Results

    • Minimized disruption to the utility’s operations by using a high performance and highly-available Oracle Database Backup Cloud Service to backup critical revenue collection and maintenance data up to 3 times faster—just 11 hours instead of 32 hours—and restore the database up to 8 times faster—in 5.5 hours compared to 40 hours
    • Cut OpEx—including 3,000 tapes, courier service, two data center operators, and one backup administrator—by roughly $10,000 by using pay-as-you-go model with Oracle Database Backup Cloud Service rather than purchasing and transporting physical tapes, maintaining equipment, and deploying resources to perform manual backup
    • Ensured continuous access to critical business information, such as revenue collection and maintenance schedules for electrification projects, and met compliance requirements by enabling 24 x 7 access to backups anywhere via internet rather than waiting for two days to transport the tapes from offsite and restore the data on site. 
    • Reduced business risk and enhanced data security by eliminating possible loss of backup tapes in transit and minimizing opportunities for data breaches
    • Enabled IT staff to focus on more strategic tasks, such as analyzing and improving the backup window, rather than spending time to make multiple copies of backups
    • Supported future expansion to other critical applications by gaining virtually unlimited capacity and no upfront capital expenditure with Oracle Database Backup Cloud Service
