First Full-Featured Unlimited Online Backup Service for Apple OS X;
MozyHome for Mac Immediately Available at $4.95 Per Month

SALT LAKE CITY, Utah — Thursday, May 1, 2008 — Mozy, Inc., part of the
Cloud Infrastructure and Services Division of EMC (NYSE:EMC), today
announced the release of ( MozyHome for Mac, the
industry’s first unlimited online backup service for the Mac. Mac users in
the home can now safely and cost-effectively back up all of their digital
information over the Internet. With more than 700,000 total users worldwide
and 6.2 billion files backed up, Mozy is the leading online backup service
of choice for consumers and small businesses.

“Mozy is honoring its roots by augmenting its service to consumers and
small businesses,” said Vance Checketts, chief operating officer for Mozy.
“We’ve had more than 43,000 individuals participate in our public beta and
have devoted thousands of hours of development to this new MozyHome for Mac

Designed as a consumer service, MozyHome for Mac offers 2 gigabytes of
online backup absolutely free with no expiration date, or $4.95 a month for
unlimited online backup capacity. Mozy automatically protects all computer
files including photos, music, videos and financial documents from data
loss in the event of hard drive crash, accidental deletion, natural
disaster or theft. All files are encrypted with 448-bit Blowfish encryption
and the encrypted files are transferred via a 128-bit SSL connection — the
same encryption used for online banking — during the backup process for
extra security. After the initial backup, Mozy only backs up incremental
changes to files and folders, meaning subsequent backups run extremely
fast. In addition to the most recent backup, Mozy keeps 30 days worth of
file versions as well. In the event of data loss, files may be recovered
via the Mozy client software, downloaded from the Mozy website, or by
ordering the files on a set of DVDs from Mozy.

“I had just completed my transition from Tiger to Leopard when my hard
drive crashed,” said Donald Malm who participated in the MozyHome for Mac
beta. “The restore of all my data from Mozy was completed without a single
error. My Quicken data was exactly where I had left off the day before the
crash. Never have I made a better purchasing decision since I started in
the insurance and financial system design industry 52 years ago.”

Later this summer, Mozy will release a business version of its Mac service
to enhance its MozyPro and MozyEnterprise offerings. More than 20,000
business customers already trust Mozy to back up their data, and Mozy is
currently backing up more than 7.5 petabytes, the equivalent to 7.8 million
gigabytes, across multiple data centers. Businesses interested in an online
backup service for the Mac can sign up to be notified at

With the addition of the MozyHome for Mac service, EMC offers Mac users the
industry’s most robust backup and recovery options. Other data protection
offerings for Mac users include
( EMC Retrospect
for Macintosh and ( EMC LifeLine software.
