Rsync not updating files

I don't need something as sophisticated as a CRC diff check; files with different timestamps and/or file sizes count as changes.I get the impression from the man page that it should be possible, but I need a little guidance on what set of parameters to pass "-v" turns on verbose mode, so you can see what it's doing (it lists the files as they copy), and "-P" enables progress, so you can see how long it's taking to copy each file (percentage copied, time remaining, etc), and allows you to see how far through the copy you are.So wondering how can I modify the rsync command to send out only newly added files. It goes a lot faster if it doesn't have to juggle tens of thousands of files.Thanks This forces rsync to skip any files which exist on the destination and have a modified time that is newer than the source file. Another option is to just unzip and if you are using a modern version of the tool it seems it will give you an interactive mode.The following command will recursively copy all files from the local filesystem from /var/www to the remote system at 10.1.1.1.Note the following: Use the --ignore-existing flag to prevent files from being copied over that already exist on the remote server.I recently needed to use rsync to only copy over files that did not already exist at the other end, so this post documents how to do this.

It just limits the files that the receiver requests to be transferred.

This option is normally used when you are copying to a remote rsync server over a slow network.

In this instance it will compress and instantly decompress the files which will only increase your CPU uage with no benefit.

This option can be useful for those doing backups using the --link-dest option when they need to continue a backup run that got interrupted.

Since a --link-dest run is copied into a new directory hierarchy (when it is used properly), using --ignore existing will ensure that the already-handled files don't get tweaked (which avoids a change in permissions on the hard-linked files).

(If an existing destination file has a modification time equal to the source file's, it will be updated if the sizes are different.) --update does skip files when the mtimes are identical (which is not what the wording implies). I believe the wording would be better understood if it said "only source files which are newer than destination will be copied"[email protected] "only source files which are newer than destination will be copied" ..source files that have same modification time as their destination file counterparts, but have different sizes. (Chris already covered that, thanks) From my experience with rsync, a 1TB partition copying is too large to be efficient. This is nice because you can see what it's trying do.
