Defender utilizes the journaling function of the mail server to send a copy of all inbound, outbound, and internal mail to Defender.

Yes, the data is compressed when it is stored in the Defender archive.

Stored email records are not encrypted, but imbedded security checks in backup and restore files are encrypted to ensure that no data has been altered or deleted.

Backups are set up through the Defender web interface. You can schedule Defender to create regular full or incremental backup fi les as well as create a full backup file at any time. Backup fi les are stored on NFS

or Windows share drives and can be stored to disk or tape by whatever backup software is already being utilized.

Defender utilizes the journaling function of the mail server to send a copy of all inbound, outbound, and internal mail to Defender.

There are 4 user security levels in Defender. Individual Users can only access and view mail from their own mailbox and have no configuration rights. Search users have global search rights but no configuration rights. Configuration users have configuration rights but no search rights. Administrators have full access to the Defender for configuration and mail search and view.

Search is possible on to, from, cc, subject, attachment name, date ranges, and text of the email body and attachments.

Yes. Users can search on all alpha text from the email and all attachments. Defender is not able to index text contained only in graphics (jpg, pdf, etc.) or text in encrypted or password protected documents.

Yes. Because of the large amount of index space that can be required to index numbers, this is a configuration option that can be turned on or off, depending on individual company requirements.

Finding and retrieving attachments is easy. Use the Defender Archive Search to locate the email message containing the attachment, Once you find the correct attachment, it can be viewed, saved, and/or restored back to your in-box.

Yes, since the Defender is a standalone appliance, it does not physically attach to an email server. This allows you to point multiple email servers to the Defender.

Yes, the Defender is capable of archiving email messages for more than one domain. However, it can work with only one Active Directory, so user access for multiple domains would have to be handled manually.

Yes, Defender works with Active Directory. It can be set up to auto-generate user accounts on Defender as well as provide authentication with AD. Defender can not work with multiple AD farms.

Defender receives a copy of each message from the email server, indexes that message and stores it in its own internal storage. The original message, still residing on the email server, can be edited or deleted, but the archived message is always secure and unchanged in the archive.

Defender is designed to be both comprehensive and easy to use at the same time. With a single user likely to get and send over 10,000 emails each year, there are simply too many emails to manage individually. Unlike archive solutions that require IT or end users to manually intervene to move mail to the archive, Defender automatically captures and stores every email record. Users simply delete mail from their mailbox when they’re done with it and rely on Defender if they need to view the information again.

Yes, existing emails can be extracted from the server and archived to Defender. For MS Exchange, a utility called Xmerge is used to convert Exchange files into PST files. These files can then be converted into inbox formats and imported into Defender.

RAID (redundant array of independent disks) combines multiple hard drives into a single logical unit. Instead of seeing several different hard drives, the operating system sees only one. RAID 5 and 6 create a fault tolerant array of disks that uses parity data that can be used to reconstruct a single disk in the event of a disk failure. If one disk fails, it can be replaced by a new drive and the RAID management software automatically redistributes the data.

No. Defender does not support archiving from a web mail server.

The exact quantity of emails a Defender can hold varies greatly depending on email size. Companies that send large attachments will store less emails than companies with small email sizes. Based on an average message size of 75kb per message, Defender can hold approximately 1 million to 140 million messages depending on model and email size.

Determining the appropriate Defender to purchase depends on the volume and size of emails particular to your company and the length of time you want to keep your email records. The Defender Sizing Chart  can help you determine which Defender is right for you.

Yes, some configuration required on the email server to turn the journaling feature on and point mail to Defender. Complete instructions can be found in the Defender Installation Guide.

Defender looks like a regular mail server to the main mail server, so the main mail server will store undelivered mail and continue to retry sending until mail is successfully delivered. The setting for how long the mail server will retain mail and retry sending is configurable on the main mail server.

Defender is designed to store many years of mail, depending on mail load, mail size, and the sizeDefender being used. When Defender starts to get full, informational and then warning messages will be sent to the Administrator. The Administrator can roll off old mail to create room for new mail. Defenders can also be upgraded within hardware case (i.e. 1U, 2U, and 3U units). Upgrading from one hardware case to the next hardware case will require purchase and installation of a new Defender.

All mail is completely erased from the Defender BEFORE the Defender is returned to ArcMail. This is done by contacting Tech Support at 888-790-9252 and requesting and RMA and data deletion assistance.

Defender is compatible with any standard SMTP mail server capable of journaling mail to an external address. Compatible mail servers include:

Exchange 1995

Exchange 2000

Exchange 2003

Exchange 2007

Lotus Notes

SendMail

postfi x

Email records that have been rolled off are no longer visible from the search screen. If data that has been rolled off needs to be searched, the fi les can be easily restored to Defender.

A SPAM and Virus filter should be in place in front of the mail server to filter out unwanted mail. Defender then sits behind the mail server so that it can capture incoming, outgoing, and internal mail.

For internal and most external mail, Defender does “single instance storage”, which means if one person in the company sends a mail to 100 people the company, Defender will store that mail only once. Mail sent to the company from outside the company may sometimes contain different routing information or Mail ID information, resulting in two mails that are similar but not exact. In this case, Defender will store a copy of both mails.
