Executive Summary
Much of the content produced in mid-market and enterprise companies now consists of email, documents,
presentations, and other types of unstructured information. This explosion of information has a significant impact
on storage spending—as well as on IT’s ability to meet the needs of its internal customers and business units—and it
can lead to the use of any number of disparate tools just to protect applications and keep them running.
Symantec archiving and backup information management solutions are engineered to support today’s most
common Microsoft® environments. Unlike typical solutions focused only at the application level, Symantec archiving
and backup solutions address the total data infrastructure (applications, servers, and networks) in order to unify
content sources, apply retention policies, reduce backup windows, shorten recovery times, and optimize storage
resources. Symantec makes it easier for companies of all sizes to store, manage, protect, and discover Exchange®
and Windows® file servers, with the PowerVault DL Backup to Disk Appliance powered by Symantec Backup Exec’s
new Archiving Options, built on market-leading Symantec Enterprise Vault.
What is Archiving?
What is Archiving? According to Answers.com, archiving means: “To compress one or more files and folders into a
single file for backup or transport…. "Archive" implies data retention, and archived data are typically stored in a
secondary location for backup and historical purposes.” PC Magazine defines email archiving in the following way:
“Retaining e-mail messages for historical purposes or to be in compliance with industry regulations…”
The PowerVault DL Backup to Disk Appliance powered by Symantec Backup Exec’s Archiving Options offer features
that closely resemble these definitions. Archiving is a way of moving data from a “Content Source” – in Backup
Exec’s case, an Exchange Mailbox or a Windows File Server with File Shares – to cost effective storage for long-term
retention. This activity has useful benefits for the content source. Generally, Exchange Servers or Windows File
Servers often use expensive primary storage, that is, storage arrays that provide a high level of performance for the
applications those arrays are serving. Over time, as old data is maintained in Exchange Mailboxes or user shares on
File Servers, the sheer mass of this older, infrequently-accessed data can force Administrators to spend a significant
amount of money to increase the size of this primary storage. However, there are reliable, cost-effective storage
options on the market that can store this data. While Exchange administrators wouldn’t want to use these storage
options in place of fast primary FC or SAS storage, why not move this old data out of the Exchange Server and store
it on those more cost-effective storage systems? This is the problem archiving solves – it gives Administrators a way
to clear out the older and infrequently-accessed data on Exchange servers and File servers. Administrators can
apply data lifecycle policies to this data so that an orderly removal of archived data takes place.
This storage management function is at the core of the Backup Exec 2010 Archiving Options. Archiving moves data
from expensive storage to more cost effective storage suited for long term retention, allowing Exchange Servers and
File Servers to be repositories of the newest and most frequently accessed data. A number of other benefits are
also included with Backup Exec’s Archiving Options:
