Of course, there are many e-discovery solutions being offered in the market, some from vertical market developers and others from larger storage system and backup vendors. For example, EMCs eDiscovery Solution, which combines EmailXtender and some Documentum wares; Mimosa Systems NearPoint e-mail archive software; Orchestrias Active Policy Management; and Symantecs Enterprise Vault Discovery Accelerator all come to mind. Read more here about compliance issues and products.However, most solutions on the market focus on the management and lifecycle for current e-mail and online messages. A couple of differences with Index Engines approach struck me.First, instead of handling the current message store, the Index Engines product targets old archives found on tape. Now, the current messages are very important, for sure, but the old, dusty tapes hold the very files that will be the toughest to handle and will be the most expensive to dig through in a discovery motion. And it never fails that the file you want is on the very last tape in the stack. Even better, the Offline eDiscovery system is an appliance and it sounds easy to set up and run. Its a turnkey approach that requires the appliance, the tape drive and the tapes. Its self-contained. The installation and processing of these pages is a special project, but one that wont kill your everyday workflow. Afterward, the real chore becomes one of feeding it the tapes. Certainly, you can find someone in your organization who knows the front side of a cart from the back and who has the patience to keep feeding the beast until the job is done?
