If you’d like to learn more about cron, check out this Media Temple community article. h or –help: This prints a help page that has useful information about using rsync.Īs you might imagine, rsync has many other useful options, and it’s worth checking them out when you have time.Ĭombine rsync with cron to create scheduled backupsĬron is a useful tool that could (and should) have its own article, but for now we’ll just cover a couple of basic functions so that you can automate your backups (or just about anything else, if you’re feeling adventurous). This option deletes any files or folders in the destination that aren’t at the source. –delete: This flag isn’t used here but it is a common feature of rsync. This is especially useful when copying large amounts of data. v: As with many other commands, this option asks for verbose output. a: Copies files recursively and preserves users, groups, symbolic links, file permissions, and timestamps. To accomplish this, we drop the slash after directory1: rsync -av path/to/directory1 /path/to/directory2/ In the example above, the contents of directory1 are copied into directory2, but directory1 will not be created in directory2. An important consideration here is the final slash (/) in the file paths of the command. This will copy the contents of directory1 into directory2. To get started, open a terminal and execute the following command, replacing the file path info with yours: rsync -av /path/to/directory1/ path/to/directory2/ We’ll start with the most basic rsync format for copying (syncing) files. You’ll also need to be at least a little familiar with the Linux CLI and (very) basic server administration.You can also use one of the several high quality wrappers for Windows. Our OS will be Linux Ubuntu 16.04, though most unix environments (including Mac) support rsync and even have it packaged as part of the software.These differences are particularly meaningful when making regular backups, copying large sites or applications, and especially when sending that data over a network. Another is that it is possible to compress the data as it’s being copied. One is that rsync only copies the delta (difference) between the files at the source and destination, possibly saving copious amounts of system resources. But there are a few reasons that you should consider using rsync instead of cp. Most of the time, cp is perfectly adequate. You may be wondering why you would want to use rsync instead of the simpler ‘cp’ command. We’ll cover a few basic uses of rsync and walk through a few examples. For this reason, rsync is often used to copy data, make backups, migrate hosts, and bridge the gap between site staging and production environments. Rsync can be used to quickly move large amounts of data to both local and remote destinations. For most admins, this is their bread and butter. If the delete option is enabled, it would delete "Folder A" and it's underlying content, and then sync "Folder with Lots of Stuff" and then it's underlying content.Originally created in 1996, rsync (or “remote sync”) is a versatile file copying utility for unix based systems. unless you have the "delete" option enabled. when the sync job runs, it's going to have both folders (and the content of those folders) on the target drive. Just keep in mind if you rename "Folder A" to "Folder with Lots of Stuff" on the source. After the first sync, it will only sync changes. After the first sync (which it has to sync everything, assuming it is going to a blank target). Thanks.Īre you using the plugin? That's how rsync works. I am pretty sure that's what I have to do but want to make sure so that I don't screw something up on either the server or the backup server by using a wrong command. To do this do I add the '-ignore-existing' option in the Extra Options box? For the next time, I only want to sync what is new not the entire directory again. Everything is going fine but taking forever because of the large amount of data being sync'd. I am rsync'ing my Movie directory to a backup OMV server.
