I work at a medical clinic where we have about 30 users accessing the main 3rd party medical software on a Windows 2003 terminal server. Data files are accessed and changed constantly and we need a failover system that replicates data at the byte level in real time. We are trying out Double Take but this software is very expensive. I like the failover feature they provide ALOT! but can do without it if someone knows another reliable product that replictaes the root drive and our secondary data drive. Any ideas?
