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

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

RsyncRsync not only transmits fast, but also in the transmission, can compare to copy the content and the local side data difference, if has the difference,Only the differential data is backed up, and if there is no difference, you do not need to back upTwo ways to work:1. Run on this machine, as with the CP command; for example: rsync-av/etc/tmp2. Run between two hosts via SSH, for example: rsync-av-e ssh

Two Rhel5.6web servers, which ran Apache, the directory is/va/www/html, now want to put online web data in real-time backup to another Web server, that is, this "another Web server" as a real-time standby machine, Here I refer to the Web machine on the line as the source server, as a real-time standby server called the target serverExperimental process:Part I: Configuring the target server:#service iptables Stop#setenforce 0#yum Install httpd#service

: Incremental backup, only the modified content is transferred Can be decompressed in real-time during transmission, reducing bandwidth consumption Can keep the original file permissions, events, soft and hard links Native replication supported, remote replication supported 3.

If the server disables password logon, you must use KEY,RSYNC-E "Ssh-i key" to resolve it, but the password requires non-interactive input (manual input), and scheduled task execution cannot be manually guarded.Combining expect can realize automatic input password Instance Code The code is as follows Copy Code #!/usr/bin/expectSet Timeout 30Spawn Rsync-avz--delete--exclude-from

Feature Description:The script is used to transfer the local directory to the remote server on a regular basis (in conjunction with crontab), with each execution generating a time-named directory, and the current version of the data is linked to a symbolic link with the first name, so it is easy to find and recover. Before the data transfer is complete, it is transferred to the TEMP directory, which is named "Time-incomplete". Backups older than 10 days will be deleted and log files older than 1
