Thread: Synchronize large directories: how?

how can best syncronize large directories between laptop , several desktop machines?

have used unison in past, unfortunately, unison directories gives me error:
"fatal error - lost connection server"
, on console shows:

"fatal error: trying transfer data in 1 go.
if happens during update detection, try to
synchronize smaller pieces of replica first
using "path" directive."

have searched mailing list , other web sites there seems no solution other manually splitting synchronization chunks not practical in case.

-- there other alternatives unison can handle larger file areas? there solution unison problem?

i use cp command this. have both ways though if files changed on both machines. cp cpommand use won't overwrite same on target machine. use nfs connect shares, work on ssh , samba.

code:

    cp -urvp /pathto/externaldrive/* /pathto/backup/directory/  do?      cp         copy command      -u         update new or changed files newer date      -r          recursive sub directories      -v          verbose, tell me happening      -p          preserve file attributes
