A public authority providing public services for the financial and commercial heart of Britain needs to be certain its data is safe and protected from disaster. And as is ever the case in public services, it needs to be cost-effective. So when the City of London was looking for a deduplication solution to replace an Asigra televaulting solution, it turned to Symantec. Complementing an existing Symantec NetBackup implementation, Symantec NetBackup PureDisk is deployed to make disk backups more cost efficient by eliminating the backup of duplicate data. Used in support of both remote site and data center deduplication, NetBackup PureDisk has enabled the City of London to reduce the volume of data backed up in the main production data center by a factor of 20―and by a factor of 42 in the disaster recovery environment. It is also providing financial savings relating to tape management and offsite storage.
