If you get “0” value, it means that IPv6 is enabled and “1” means it is disabled.

It can be a good idea to test what will be transferred before actually doing it to make sure you aren’t going to copy files that you don’t want to. (Conversely, any files that have an older timestamp are not copied over).ġ rsync –update -raz –progress /var/Use –dry-run to see what will be copied The behavior is now like this:Īny files that exist on both local and remote that have a newer timestamp on the local server are copied over. However you may want to copy files over the have been updated more recently on the local filesystem which is done with the –update flag. In the case I was talking about, we didn’t want to overwrite any files at the other end. By adding this, we eliminate behaviors 2 and 3 in the list above and all that is done is this:ġ rsync –ignore-existing -raz –progress /var/Update the remote only if a newer version is on the local filesystem Use the –ignore-existing flag to prevent files from being copied over that already exist on the remote server.
The following command will recursively copy all files from the local filesystem from /var/Note the following:Īny files that do not exist on the remote system are copied overĪny that have been updated will be copied over, although note that rsync is extremely efficient in that only the changed parts of files are copied and if the file is exactly the same if it is not copied over at allĪny that have been deleted on the local system are deleted on the remoteġ rsync -raz –progress /var/Ignore existing files Note that all the examples shown in the post are for copying files from the local computer to a remote server/computer.
