Useful for inclusion in scripting when the terminal output is not required

-u : Skip updating target files if they are newer than the source.

-v : Show progress overall, outputting information about each file as it completes it.

-list-only : Only show the list of files that rsync would transfer.

-n : Dry run the command without transferring files.

But, some of those might be contrary to what a user needs, so breaking it out into the specific functionality might be the right answer. Often this works how the user wants and no significant changes are necessary.

-o : Preserve user ownership (which is restricted to only superusers when dealing with other user’s files).

-r : Recurse through directories (as opposed to only working on files in the current directory).

The -a is equivalent to -rlptgoD, which breaks down to: Passing parameters such as -a for “archive” is quite common as it is a “meta-parameter” that automatically invokes a handful of others for you. It’s ordinarily desirable to pass rsync a few parameters to ensure things behave the way a human would expect them to. In its simplest form, rsync can be told to ensure that a file in one location should be the same in a second location in a filesystem. On the command line, rsync is generally invoked using a handful of parameters to define how it should behave since it’s a flexible tool.

Working with rsync is easy and can be used on the command line, in scripts, and some tools wrap it in a nice UI for managing tasks. This is also the case with macOS, *BSDs, and other Unix-like operating systems. Since it comes packaged with most Linux distributions by default, it should be easy to get started.

It can also do a quick hash check of files on the source and destination to determine whether or not it needs to transfer a new copy, possibly saving significant time and bandwidth. To accomplish this efficiently, by default, it will check the modification times of files.

Also, rsync provides the ability to synchronize a directory structure (or even a single file) with another destination, local or remote. It checks to see if files exist in the destination before sending them, saving bandwidth and time for everything it skips.

The rsync tool can recursively navigate a directory structure and update a second location with any new/changed/removed files. One of the most useful tools in a sysadmin’s belt for this kind of task is rsync. Inspired by lanzz's comments, another idea could be to run rsync at startup to backup the content of a folder under Ubuntu One, and start Ubuntu One only after rsync is completed.Admins (or normal users) often need to back up files or keep them in sync between multiple places (including local and remote) without transferring and overwrite all files on the target every time. If anything goes wrong and U1 delete my data on B, I always have them on A. In this manner any change in A will be appled to B, which will be detected from U1 and synchronized to the cloud. The I simply keep synchronized "folder B" with Ubuntu One.I need it to be one-way only from A to B any changes to B must not be applied to A. I need the answer of my current question to create a one-way sync of "folder A" to "folder B" ( cron a script with rsync? could be?).So I thought to add a step further to keep a backup copy of my data: I used Ubuntu One to synchronize data between my computers, and after a while something went wrong and all my data was lost during a synchronization. It should work automatically in this way: whenever I create, modify, or delete stuff from the original folder those changes should be automatically applied to the sync-folder.įinal goal is to have a separated real-time backup copy, without the use of symlinks or mount. I would like to have a synchronized copy of one folder with all its subtree.
