EdgeSafe PST2PST solves a problem not readily solvable in any other way.
With email having become the major element in the communications suites of most firms, the issue of how to effectively backup the personal mail store (pst) has become a vexing problem.
We have tried everything -- scripted closed file backup to the server in the middle of the night, user-controlled closed file backup at the start of the day, during the lunch hour, and at the end of the day -- nothing works seamlessly, regularly, or consistently, except PST2PST.
Once installed, it is a set and forget application that maintains email backup in realtime, such that in the event of a workstation disaster, email is easily restored. Without this utility, restoration was nothing short of a nightmare. The email backup repository (on the server) is archived, such that even if an wholesale disaster were to occur, all personal mail stores could be easily restored.
I would recommend this application to anyone.
