VMware VADP

VMware VADP produces in-depth details of sizing, deployment, and data flow, providing a total

VMware data protection plan that can be used in conjunction with Avamar on Vblock systems.

VMware Changed Block Tracking

VMware Changed Block Tracking is a VMware feature that helps perform incremental backups.

VMware Data Recovery uses this technology, and so can developers of backup and recovery

software. Avamar leverages this feature for efficient backup of VMware guest servers.

VMware VMDK

VMware VMDK is a file format used for virtual appliances developed for VMware products. The format

is a container for virtual hard disk drives to be used in VMs like VMware Workstation or Virtualbox.

VMDK is an open format.

A VM is a tightly isolated software container that can run its own operating system and applications as

if it were a physical computer. A VM behaves exactly like a physical computer and contains it own

virtual (software-based) CPU, RAM, hard disk, and network interface card (NIC). A VM is composed

entirely of software and contains no hardware components whatsoever. As a result, VMs offer a

number of distinct advantages over physical hardware. An operating system can’t tell the difference

between a VM and a physical machine, nor can applications or other computers on a network. Even

the VM thinks it is a “real” computer.

Data Domain target hardware

EMC Data Domain is a storage target for deduplicated backup savesets. Data Domain targets

provide:

 High-speed deduplication of backup data, with a consistent ingestion rate, regardless of how

well any particular data set will deduplicate. A good example is deduplication of unstructured

data backups. Even though databases do not typically deduplicate very well, a Data Domain

target does not bog down while ingesting and storing the backup.

 More backups, and faster completion of backups, which relieves pressure on already tight

backup windows.

 Network-efficient replication. Data Domain sends only deduplicated and compressed data

across the network, requiring a fraction of the bandwidth, time, and cost of traditional replication

methods.

 End-to-end data integrity. Data Domain and its Data Invulnerability Architecture (DIA) provide

safe and reliable continuous recovery verification, fault detection, and healing.
