Faster, Bigger, Leaner – Serco Conquers Steep Data Growth

Serco Pegs Savings from DXi/Scalar Solution at $2 Million

With a rapidly expanding customer base, Serco has seen what was a 50TB technology infrastructure three years ago explode to 800TBs, with petabytes soon to come. The company turned to an integrated Quantum DXi® and Scalar® backup solution.结果：重复数据删除减少了高达96％的数据量，恢复时间减少了五倍 - 超过五年的储蓄预计将是200万美元。

Lengthy Backup Window, Restore Times

SERCO提供管理和外包解决方案，包括工业技术解决方案。一个示例是常用的交付基础架构（CDI）-A托管存储和数据保护基础架构，客户端以每千兆字节为基础远程使用。

A byproduct of CDI’s success is that its legacy tape-based solution was struggling to back up the customer data Serco is contracted to protect. The backup window was already running from 5pm on Friday to 8am on Monday, and any overrun could result in penalties for breaching service level agreements.

In addition, restores and disaster recovery were labor-intensive. With some Serco clients having up to 600 tapes under management in a monthly cycle, media management was a nightmare. Restores could take one or two days to complete.

“A disk-based backup system was the obvious answer, offering scalable deduplication and replication in one integrated solution,” says Duncan Smith, a Serco Product Manager responsible for CDI.

Benefits: Deduplication, Enterprise-Wide Backup

Serco selected Quantum DXi8500 disk-based backup and replication systems and Quantum Scalar i500 tape libraries to provide flexible deduplication, a scalable architecture, and enterprise-wide backup and disaster recovery for Serco’s clients.

The solution’s deduplication technology has reduced the amount of data stored by up to 96 percent, as well as lowered the total amount of data replicated continuously between two sites from 480TB to 85TB. Deduplication has also cut the demand for tape storage, resulting in tape cost savings and streamlined administration.

此外，备份数据所需的时间已从整个周末删除到仅需四个小时。RESTERE现在速度快五倍，因为可以直接从DXI系统检索数据。

总体而言，该系统预计将节省5年多年的SELCO 200万美元。那么Serco没有量子解决方案的情况会在哪里？

“We would probably have a hangar full of tapes, a fleet of vehicles ferrying tapes around, and a very large bill at the end of it,” says Duncan.
