Symantec has released Norton Ghost 15, a PC backup and recovery software that offers 25G and 50G Blu-ray Disc support and is Windows 7 compatible.

The company said that the new version introduces a new cold imaging feature that images computers without installing the product. In addition, it uses ThreatCon indicator to automatically back up PCs in the event of a severe security threat.

According to Symantec, with Norton Ghost, lost or damaged files can be recovered and restored in the event of a system failure, even if the computer’s operating system does not start. It also allows backup of an entire system or specific files and folders while saving recovery points to offsite locations using FTP. The new software allows users to decide when to back up their system, either on a schedule or based on an event.

In addition, Norton Ghost works with most storage drives, including external hard drives, networked drives, and recordable and rewritable CDs and DVDs. It also includes a backups feature, which allows users to back up their computers without having to shut it down. It is also supported by Windows 7 Bitlocker, providing data protection through drive encryption and integrity checking, the company said.

The cold imaging technology backs up files and allows users to image a PC before any software is loaded so that factory settings remain intact, Symantec added.
