Remote Automatic Backup rsync + ssh + sshpass: the advantages of mutual automatic backup between remote servers (www.2cto.com rsync) The vast majority of O M personnel know that, simply put, only the files that have been modified are backed up, reduce data transmission volume. At the same time, it can transmit data th

Okay, finish this. A very important configuration, is the password file, in Figure two, we must not pay attention to a folder, that is, etc folder, good, is

Cross-server/client BACKUP command: rsync usage Recently, we often need to deploy environments on a new server. Many things can be backed up directly from other servers without re-downloading and installing them. The rsync command is used: First, download rsync and install it on the "source server". take part in Bai

Inotify + rsync implements real-time file backup 1. inotify inotify is a powerful fine-grained and asynchronous file system event monitoring mechanism. The Linux kernel has been added to Inotify since 2.6.13, inotify can be used to monitor various events in the file system, such as adding, deleting, modifying, and moving. However, inotify only provides the C language interface, which is inconvenient to call
