Hi people, Does anyone have experience with a software that could be used for real time replication of exchange stores. I found: Double Take and Geo Cluster (too expensive for me), Veritas-volume replicator, Marathon Technologies-FT Server, Legato-Co-Standby Server. Only Legato offers tryal version, but I would be happy to get a piece of advice from smb who used one of these. And one more question. What do you think is there any chance that this kind of software recognise a logical error on source server and stop replication instead of copying the error to the target server? Thanks Zoran
