  1. Guys,

  2. Few guru mentioned about 'rsync'. That's good idea it seems. also,

  3. Do you think 'AFS' can be useful for this requirement. As AFS cache only change byte (or file ?).

  4. one more important question about AFS :-

  5. Does it run over UFS etc (like NFS) or we need to implement a whole file system as 'AFS' to use it ? Does it need to reconfigure ..whole thing ??
