Common Use Cases

This section provides the most common use cases for the DL1000 and provides a high-level overview of

the information and procedures required for each scenario. Where required, references to additional

information is provided.

Protecting Machines

The AppAssure backup and replication technology provides advanced protection of VMs or servers while

enabling flexible application and data recovery. When a machine is protected, full and incremental

snapshots of data are captured and stored in the core’s repository. The AppAssure protection process

leverages two key technologies – Snapshots and the Dell DL1000 Smart Agent that are described below.

Snapshots

The AppAssure Agent for Windows uses Microsoft Volume Shadow copy Service (VSS) to freeze and

quiesce application data to disk to capture a file-system-consistent and an application-consistent

backup. When a snapshot is created, the VSS, writer on the target server prevents content from being

written to the disk. During the process of halting of writing content to disk, all disk I/O operations are

queued and resume only after the snapshot is complete, while the operations already in flight will be

completed and all open files will be closed. For more information, see topic Snapshot Process.

Dell DL1000 Smart Agents

The Smart Agent is installed on the machines that are protected by the DL1000 Core. The Smart Agent

tracks the changed blocks on the disk volume and then snaps an image of the changed blocks at a

predefined interval of protection. The incremental block-level snapshots’ forever approach prevents

repeated copying of the same data from the protected machine to the Core. When the snapshot is ready,

it is rapidly transferred to the Core using intelligent multi-threaded, socket-based connections. For more

information, see the topic Dell DL1000 Smart Agent.

Deploying Smart Agents

You must install the AppAssure Agent Installer on every machine in your environment protected by the

DL1000 Core.

NOTE: These procedures are a summary. For detailed information, or specific instructions for Linux

Agents, refer to the Dell DL1000 Appliance User’s Guide.

Step 1: Obtaining the Agent Software

Smart Agent software can be obtained by following one of the following methods:

• Download from the AppAssure Core — Log into the Core Console and download the software to the

agent machine. Select Downloads from the Tools tab, and then download the web installer for the

Agent component.
