I'm looking for some suggestions from in choosing a file/folder synchronization application that workS well over WAN links. I have several locations that I need to replicate data to my datacenter for backup. Currently we FTP a compressed copy, but the time frame to move all this data is starting to pose issues with the backup window. Would like to have a cost conscious, secure, centrally managed, bandwidth throttled (maybe use BITS) solution. Any help would be appreciated, but would like to hear from people currently using this type of solution. Thanks!
