rsync between freenas server

Just wanna give a clue how to rsync between freenas server

first, you need atleast 2 freenas server, one as freenas source and other as freenas target

to make it simple, use the same user login and password, because we need to access it using ssh

this is the example using rsync

rsync -arvz --exclude-from=/mnt/vol/itd/itmgr/exclude.txt --log-file=/mnt/vol/itd/itmgr/log/dutamas-`date '+%Y%m%d_%H%M%S'`.log --no-perms --no-owner --no-group --delete --progress fda:/mnt/freenas/ /mnt/vol/dutamas/

• rsync is the apps
• -arvz is the parameter that connect it
• –exclude-from= is excluding file
• –log-file= is the log file while sync the server
• –no-perms is ignoring permission
• –no-owner is ignoring owner
• –no-group is ignoring the group owner
• –delete is delete the file if the sync server is not same
• –progress is showing the sync progress
• fda:/mnt/freenas is server source
• /mnt/vol/dutamas is server destination

question! what is fda

fda is a mapping host, we can create the file on ~/.ssh/config below is the sample file

Host fda
    HostName 192.168.60.17
    IdentityFile ~/.ssh/itmgr_rsa
    User root

Host fta
    HostName 192.168.70.3
    IdentityFile ~/.ssh/itmgr_rsa
    User root

Host fsa
    HostName 192.168.5.7
    IdentityFile ~/.ssh/itmgr_rsa
    User root

we do have 3 source server, fda, fta and fsa, we defined the host name, and we also defined the identity file, because we do not want to type password each synchronizing . and finally we use user root to access each source server
