It is also possible to use rsync without using rsh or ssh as the transport. (See the following section for more details.) Connecting to a RSYNC Server This would list all the anonymous rsync modules available on In this case it behaves like an improved copy command. You can also use rsync in local-only mode, where both the source and destination This difference becomes particularly important when using the -delete option. Without a trailing slash it means "copy the directory". The files are transferred in "archive" mode, which ensures that symbolic links,ĭevices, attributes, permissions, ownerships etc are preserved in the transfer.Īdditionally, compression will be used to reduce the size of data portions of the transfer.Ī trailing slash on the source changes this behavior to transfer all filesįrom the directory src/bar on the machine foo into the /data/tmp/.Ī trailing / on a source name means "copy the contents of this directory". On the machine foo into the /data/tmp/bar directory on the local machine. This would recursively transfer all files from the directory src/bar Rsync remote-update protocol is used to update the file by sending only the differences. If any of the files already exist on the remote system then the This would transfer all files matching the pattern *.c from the current directory Perhaps the best way to explain the syntax is some examples: You must specify a source and a destination, one of which can be remote. You use rsync in the same way you use rcp. S upport for anonymous or authenticated rsync servers (ideal for mirroring).Pipelining of file transfers to minimize latency costs.Can use any transparent remote shell, including rsh or ssh.A CVS exclude mode for ignoring the same files that CVS would ignore.Exclude and exclude-from options similar to GNU tar.Support for copying links, devices, owners, groups and permissions.Some of the additional features of rsync are: Any changes in the other preserved attributes (as requested by options) are made on the destination file directly when the quick check indicates that the file's data does not need to be updated. Rsync finds files that need to be transferred using a "quick check" algorithm (by default) that looks for files that have changed in size or in last-modified time. ![]() Rsync is widely used for backups and mirroring and as an improved copy command for everyday use. Speed up file transfers when the destination file already exists. Many more options and uses the rsync remote-update protocol to greatly Rsync is a program that behaves in much the same way that rcp does, but has # = via remote shell rather than the rsync daemon Remote file copy - Synchronize file trees across local disks,
