Catalogic DPX Master Server: A server appliance that contains the DPX product, including the catalog and modules that control media management, scheduling, and distributed processing. This is deployed in the form of a VMware OVA or Microsoft Hyper-V template and may be referenced as the DPX Master, DPX Master Server virtual appliance, or DPX virtual appliance.

Device Server: A node to which one or more storage devices (tape, VTL, disk) are attached.

DPX Management Interfaces: A graphic interface that users can use to operate the Catalogic DPX Master Server instead of using the operating system interface such as Bash for Linux and Microsoft Windows desktop. There are the HTML-5-based DPX Management Interface and the Java-based DPX Management Interface.

DPX Block Data Protection (Block Backup): A protection and recovery model that comprehensively backs up open systems such as Windows and Linux to disk-based storage using Catalogic Software's block-level agent. Features include block-level incremental snapshot technology, Instant Access and Instant Virtualization, source and target side data reduction, Bare Metal Recovery, and application recovery. DPX Block Data Protection supports the following features:

• Catalogic DPX Open Storage Server (OSS; formerly called AROS or DOSS): A computer that can store protected data on local or attached disk storage. This is one destination for Block backups. This feature applies to DPX 4.2 and later.

• Block Backup of Linux systems requires LVM2

• Catalogic DPX Client: A computer that contains the data, applications, volumes, and operating systems that are protected with Block backup.

• Bare Metal Recovery (BMR): A feature that provides point-in-time server recovery of a DPX Client using Block backups. Recovery to dissimilar hardware is supported but manual driver installation may be needed.

• Application Recovery: A DPX Block Protection feature that rapidly recovers data from Microsoft SQL Server, Microsoft Exchange, and Oracle.

• Instant Access (IA): A feature that provides instantly writable access to data and application recovery points. A Block backup snapshot is mapped to a target server where it can be accessed, copied, or put immediately into production use as needed.

• Instant Virtualization (IV): A feature that enables customers to create a virtual machine in the VMware ESXi server from any recovery point on any Windows and Linux physical or virtual server. IV creates a virtual machine in the VMware host without restoring data from the selected recovery point. This operation does not physically transfer data to the virtual machine and makes it possible to complete a disaster recovery operation of a physical or virtual server in minutes, without recovery storage requirements.

• Full Virtualization (FV): A feature that enables customers to create a virtual machine in an ESXi server from any recovery point on any Windows and Linux physical or virtual backed-up instance. FV creates a virtual machine in the VMware host that contains a clone of the backed-up server. If the backed-up server is physical, FV performs a physical-to-virtual (P2V) operation.

• VMware Backup: A feature that exploits VMware vStor application programming interface for data protection and Change Block Tracking to enable off-host backup of vSphere virtual machines through the Catalogic DPX proxy servers, eliminating the need to install and run a backup agent on virtual machines or the VMware ESXi servers.

• Microsoft Hyper-V Backup: A feature that allows for the off-host backup and the restoration of Microsoft Hyper-V virtual machines to a primary backup destination such as the vStor Server.

Catalogic vStor: A physical or virtual appliance that can serve as your DPX primary backup destination. vStor servers can store with Block, Microsoft Hyper-V, or VMware backups.

SAN Device Server: A device attached to a Storage Area Network. Catalogic Software supports any combination of UNIX, Windows, NetWare/OES, Linux, and NDMP/NAS in a SAN.

Image Backup for Seeding: A technology used to transfer a Block Backup base to a remote location via tape, cloud, or portable disk. This is useful for initiating the Block Backup relationship when nodes exist across low-bandwidth WAN links.

Application Interfaces: A set of features that interface with Microsoft SQL Server, Microsoft SharePoint, Oracle, IBM DB2, IBM Lotus Notes, Novell (Micro Focus) GroupWise, SAP R/3, and SAP HANA.

NDMP Backup: A feature that uses Network Data Management Protocol (NDMP) to coordinate backup and restore operations between NDMP-compliant devices using vendor-specific data formats. NetApp supports DUMP and SMTAPE data formats. Other vendors may support TAR or other data formats. Vendor data formats are proprietary, thus restore operations must be performed on systems similar to the backup source.

DPX Archive: A feature allowing tertiary protection of DPX Block and VMware Backup. It can be performed to tape, disk directory or cloud. When restoring from a Block Archive, only files and folders can be recovered. Bare metal recovery, instant virtualization, and full virtualization are not supported when restoring from Block Archive.
