I am trying to duplicate a job I have going from Windows 2008 ntfs to CentOS 5 ext3 with rsync, but from Windows 2003 ntfs to Solaris 10 ZFS. The 2008->CentOS job runs as: rsync.exe -ravcz --delete-during -e "ssh -i <snip>\.ssh\id_rsa" "/cygdrive/g/<snip>/" backup@host:/home/backup and the job only transmits the delta, as hoped. The 2003->Solaris job runs as: rsync.exe -rvc --delete -e "ssh -i <snip>\.ssh\id_rsa" "/cygdrive/y/<snip>/" root@host:/mypool1/path and the job ends up transmitting the whole file over, not just the delta? I removed the -a as I have permission issues on the ZFS file system, is that the reason (-z not needed on this one)? Anything I am missing? Thanks! jlc
