![]() To top it off, it also has a graphics front-end tool, call grsync, and rsnapshot to create scheduled incremental backups, if so desired. You can also use cron to periodically create backups. With just a small knowledge of the command line, you can be backing up in no time with rsync. Remote sync can be better than other backup methods because of its speed, and because it doesn’t require any special permissions to execute an rsync command. This easy-to-use utility is commonly used for backing up data, but can synchronize files for any other purpose you choose to use it for. This makes Rsnapshot a great choice for server backups. That means you get efficient, lightweight, incremental backups that look like exactly like full-blown copies (in every way). It creates a full-blown snapshot for each run, but makes extensive use of hard links for files that haven’t changed, thereby greatly reduce the disk space required. And when you want to recover data, you transfer just the specific files that you want back to your machine (using rsync or scp or telnet or whatever). If no files were changed, no files get transferred. Instead of sending all the files again, rsync only transfers files that have been changed. The benefit comes the next time you backup. (rsync has also been ported to Microsoft Windows, Mac, and other operating systems.) The first time, rsync sends all the data over the network to your backup machine. Rsync is a UN*X command line utility, containing a special protocol and algorithm, that synchronizes files and directories from one location to another while minimizing data transfer by using fast incremental file transfers. Rsync stands for remote synchronization tool. Rsync is one of the most widely used Linux backup solutions, and in fact, it is often used by other backup tools as a foundational component.
