Technical Director Nigel Dutt approached Edward Forwood of broker Durlacher with a proposal to start a company to develop and sell the product. They consequently acquired the rights to the product and formed kVault Software Limited in late 1999 with initial funding from Durlacher. The four years from 2000–2004 saw greatly improved sales and eventual acquisition by VERITAS Software in 2004. Veritas was subsequently acquired by Symantec in 2005 for $13.5B. However, on February 1st 2016, Symantec completed its sale of Veritas to the Carlyle group for $7.4B and Enterprise Vault again reverted to being a Veritas product.

In computing, Veritas NetBackup (called Symantec NetBackup prior to Symantec's divestiture of Veritas) is an enterprise-level heterogeneous backup and recovery suite. It provides cross-platform backup functionality to a large variety of Windows, UNIX and Linux operating systems.

Veritas NetBackup -- known as Symantec NetBackup from 2005 to 2016 -- is a backup and recovery software suite designed for enterprise users. When security giant Symantec acquired Veritas for $13.5 billion in 2005, the NetBackup product was renamed Symantec NetBackup. In 2016, when Symantec spun out its Veritas storage unit, NetBackup again became known as Veritas NetBackup.

NetBackup features a central master server which manages both media servers (containing the backup media) and clients. Core server platforms include Solaris, HP-UX, AIX, Tru64, Linux and Windows.

NetBackup OpsCenter, which comes bundled with the NetBackup 7.0 distribution and replaces the NetBackup Operations Manager[1] (NOM) component used in previous versions, can manage multiple NetBackup environments. NetBackup comes with support for many hardware devices like tape drives, tape libraries, disk units. It supports, among many[quantify] other features, hot backups for major database products like Oracle; it can natively backup and restore the virtual machines of major virtualization products like VMware Infrastructure, can use Network Data Management Protocol (NDMP), and has tape vaulting. NetBackup also enables LAN-free and server-free backups in SAN fabric environments.

NetBackup: #1 in Enterprise Backup Solutions Enterprise data backup and recovery optimized for the multi-cloud.

NetBackup simplifies the protection of your information driven enterprise by automating advanced technologies and standardizing operations across applications, platforms, and virtual environments. Integrated deduplication, replication, and patent-pending virtual machine protection, helps customers improve storage efficiency, infrastructure use, and recovery times.
A single console offers multi-site monitoring, analytics, and reporting which allows customers to standardize operations and risk management. Used by global companies around the world, NetBackup easily scales to protect the largest UNIX®, Windows®, and Linux® environments.

NetBackup includes the following server and client software:
The NetBackup master server manages NetBackup backups, archives, and restores. The master server is responsible for media and device selection for NetBackup.
NetBackup Media servers are the NetBackup device hosts that provide additional storage by allowing NetBackup to use the storage devices that are attached to them.
NetBackup client software that resides on the hosts that contain data to be backed up.

The backups that are generated in one NetBackup domain can be replicated to storage in one or more target NetBackup domains. This process is referred to as Auto Image Replication.

The ability to replicate backups to storage in other NetBackup domains, often across various geographical sites, helps facilitate the following disaster recovery needs:
One-to-one model
A single production datacenter can back up to a disaster recovery site.
One-to-many model
A single production datacenter can back up to multiple disaster recovery sites.
Many-to-one model
Remote offices in multiple domains can back up to a storage device in a single domain.
Many-to-many model
Remote datacenters in multiple domains can back up multiple disaster recovery sites.
NetBackup supports Auto Image Replication from a Media Server Deduplication Pool in one NetBackup domain to a Media Server Deduplication Pool in another domain.
Notes about Auto Image Replication
Although Auto Image Replication is a disaster recovery solution, you cannot restore to clients in the primary (or originating) domain from the target master domain.
Auto Image Replication does not support synthetic backups or optimized synthetic backups.
Auto Image Replication does not support spanning volumes in a disk pool. NetBackup fails backup jobs to the disk pools that span volumes if the backup job is in a storage lifecycle policy that also contains a replication operation.
Auto Image Replication does not support replicating from a storage unit group. That is, the source copy cannot be in a storage unit group.
The ability to perform Auto Image Replication between different versions of NetBackup does not overrule the basic image compatibility rules. For example, a database backup that was taken in one NetBackup domain can be replicated to a NetBackup domain of an earlier version. However, the older server may not be able to successfully restore from the newer image.
Synchronize the clocks of the master servers in the source and the target domains so that the master server in the target domain can import the images as soon as they are ready. The master server in the target domain cannot import an image until the image creation time is reached. Time zone differences are not a factor because the images use Coordinated Universal Time (UTC).

NetBackup uses storage lifecycle policies in the source domain and the target domain to manage the Auto Image Replication operations.
