[Csync2] Csync2 use case

[Francisco Reyes]

Just found csync and trying to find out if it will work in our 
particular use case.

Have directories with tens of millions of files that need to sync 
between 3 machines.
1 machine is a backup so there won't be any changes done in it, but 2 of 
the machines are offices in different states.

Unison works for smaller directories well and even large ones.. after 
the first sync. Problem with unison is that the initial sync is a killer.
Also if there is a connection drop during the initial sync (which can 
take a day plus) the entire operation needs to start over.

Would csync2 do better in this case?
* 3 Machines
* Directories with tens of millions of files
* Need bi-directional sync support
* Need continuous sync (can setup cron)
