Example code to rsync

rsync command is used to synchronize files and folder from source to destination. It may be same or different server. If the synchronization is in between different servers we have to use ssh credentials for connecting the two.

Example given below:

rsync -ravpzHogt --delete -e ssh {source-path} {sshuser_id}@{ip/site-address}:{destination-path}

Some of the options of rsync listed below.

r - rsync to copy directories recurssively.

a - archive - presave almost anything but does not presave the hardlinks. For that we use -H.
