As we know rsync command is very helpful in taking backup. Sometime need to backup of some folder by including some sub folders and excluding some of them. by an e synchronizing with remote system we can mention folders which to be included and which to be excluded as command line options. Let us understand it by an example, suppose one need to take take backup of / by excluding /home and by including /home/user2 .
Following command help out
root# rsync -av –filter=+home –filter=+/home/user2 –filter=-/home/* / user1@remotehost:/folder
Without the delete option per directory options are only relevant on sending side, to exclude the merge files themselves without affecting the transfer. The -e modifier can do this easily. For example
root# rsync -av –filter=’:e .mp3′ host:src/dir /dst
