Using rsync to synchronize Linux VPS data rsync is a data Image Backup tool in unix-like systems. it can be seen from the software name-remote sync. Its features are as follows: www.2cto.com can mirror and save the entire directory tree and file system. It is easy to maintain the permissions, time, and soft links of the original file. Installation without special permissions. Optimized process, high file transmission efficiency. You can use rcp, ssh, and other methods to transmit files. of course, you can also use a direct socket connection. Supports anonymous transmission. Rsync is an efficient algorithm for file synchronization in unix/linux. it can synchronously update files and directories of two computers, and properly use different blocks in the file to reduce data transmission. An important feature in rsync that is not seen in most other similar programs or agreements is that images are transmitted only to the changed part. Rsync can copy/display Directory attributes, copy files, and perform selective compression and recursive copy. First, ensure that the old VPS and new VPS are installed with the same release version and are both 32bit or 64bit. it is best to disable services such as mysql and http before synchronization. First, create a non-synchronous snapshot exclude.txt: Java code cat>/exclude.txt <
