Symantec and Zantaz simplify large-scale backups
Polished e-mail and file archiving solutions offer comparable features
After the installation, there is a fair amount of configuration to be done, including setting up the document stores and paths to the database. You’ll also need to create groups and users, and then set policies for groups. Policies can be set on a per-user basis if desired, and they can override or combine with group policy.
There are tests within the installers or available as scripts that check the IIS connection to the SQL server, AD connections, and beyond, all the way through. All the multitudinous connections between the various parts of the overall system can be tested and debugged from within the installers.
The client configuration utility lets you create a custom .msi file with the options you want configured. From there, you can perform quiet installs for all users.
EAS can also archive and migrate .pst files either by simply archiving them, or archiving them, deleting the .pst file, and leaving pointers so the user can still access the messages.
The parent/child architecture of EAS is site-aware: If messages are stored locally and in a central location, EAS will give a user who clicks on a message the closest copy of the message. Offline support can automatically sync at startup/shutdown with a compressed local store, giving remote users access to archived messages even if they’re not connected to the network.
EAS also does attachment splitting. When a user double-clicks on an archived e-mail message, it’s restored, but the attachments are still just stubs, only restored if the user double-clicks on the attachment separately.
The admin interface is flexible, with multiple views, role-based administration and easy setup of policies for data archiving and management, with wizards for easy setup as well as scripting for complex rules. Different views can be saved, so that a lower-level admin would see only the options he or she would need.
Clustering allows for load balancing as well as redundancy. If a child EAS server dies, the parent and other children pick up the load. If the parent server dies, one of the children has to be promoted, which takes a few seconds. All EAS servers in the enterprise can be rebooted, promoted, and so forth from one admin console.
The First Discovery utility can search the entire archive for messages containing whatever criteria you’re looking for, in read-only mode, and export to .pst files for security audits, compliance, or litigation support. EAS Supervisor performs similar tasks, but it can also monitor new messages based on rule sets.
An AD extension adds user information and index information, so restoration of e-mail can be accomplished through the Users and Computers Windows admin tool.
All in all, these two products are quite similar in terms of capabilities and features. Either solution is likely to give you a handle on archiving. Zantaz does offer on-site setup as part of the subscription, and its solution offers more sophistication in writing rules as well as better scalability. Those benefits, however, come at considerable cost.
