Email Archiving
Analyzing the Return on Investment

EAS can provide 50%-80% cost savings in disk space and backups through compression and de-duplication. This works out to potential savings between $99,840 and $159,744 in existing storage device optimization.

Mail servers. According to research conducted by HP, the average Microsoft Exchange server can support 95GB of data, meaning a 10,000-user organization with a storage requirement of 3,900GB will need 41 servers.

As the volume and size of email grows (from 19.5MB per user per day today to 36.4MB per user per day in 2008), the organization will need to install an additional 11 servers in year one, 10 in year two and 15 in year three just to keep up with growing storage requirements. At about $20,000 per server (including hardware, software, and operating system), this yields an expense of $720,000 over the next three years.

EAS can allow organizations to repurpose at least 1/3 of existing mail servers and to reduce future mail server requirements by 40%-60%. In this case, EAS saves the organization in excess of $300,000 in mail-server expenses over a three-year period.

Backup costs. If the organization conducted one daily and one weekly backup, it would result in 12,792 backups annually. At a conservative $2.50 per tape for on-site storage, this works out to $31,980. Implementing EAS reduces the number of backups to 8,571 and the related costs to $21,427, a cost saving of approximately 33%.

Administration time. For the purposes of this example, we have assumed that implementing EAS saves an organization a conservative 40% in administrator time requirements by automating several routine tasks. (For many organizations that have deployed EAS, this figure is much more than 40%.) In dollar terms, this works out to savings in excess of $100,000 annually.

End-user productivity. We have assumed that employees spend a very conservative five minutes per week managing their mailboxes, including creating .PST files and filing important information. For a 10,000-user company, five minutes per employee per week equals 43,333 hours of lost productive time per year. At an average salary of $57 per hour, this converts to $2.47 million in total lost productivity. Since EAS can automatically manage tasks like classification and categorization, and because it effectively negates the need to create .PST files, it considerably shrinks this figure by more than 70%—saving the organization in excess of $1.7 million in lost end-user productivity per year.

Summing Up
While email has become an invaluable application in the workplace, its explosive growth is placing corporate email environments under severe pressure and driving hardware and administration costs to all-time highs. The deployment of an email archiving solution like ZANTAZ EAS can significantly lower these costs, improve IT processes within the organization and ultimately deliver a highly attractive ROI.

ZANTAZ Enterprise Archive Solution (EAS)
ZANTAZ EAS is a fully integrated family of email and file management prodhelp organizations manage their email and file storage, simply and cost-effectively. By implementing the ZANTAZ EAS family of products, organizations can fully optimize their storage needs, significantly reduce IT overhead and dramatically increase end-user productivity—all while ensuring the long-term retention, instant retrieval and efficient production of email and files in the event of a regulatory investigation or discovery request.

• Parent-child architecture—can be centrally managed and locally optimized across an organization with multiple domestic and international branches
• Single-instance storage (SIS)—applies SIS algorithm to ensure that only a single copy of the message, attachment or file is stored in the archive with links to all referring instances.
• .PST/.NSF file management—EAS provides automated tools to find, gather and archive all .PST/.NSF files without user intervention.
• Backups—EAS allows backups to occur during usage hours eliminating the need to schedule off hour backups which with the expanding time zones is difficult

With the deployment of supplementary EAS modules—such as EAS Storage Manager, EAS for Files, EAS Discovery, or ZANTAZ Introspect—organizations can realize further benefits as well, including discovery savings, file archival savings, long-term storage optimization and savings related to optimal archiving compliance.
