发现一个rsync同步神器(linux下文件夹同步增量备份神器)

全名:

Rsync time backup

其实就是rsync+time machine,原理就是简化了rsnyc操作,可以实现增量备份。

常用命令:

sh rsync.sh /home/www/mztine.com /home/www/mztine_back

rsync_tmbackup.sh -p 2222 /home user@example.com:/mnt/backup_drive

rsync_tmbackup.sh user@example.com:/home /mnt/backup_drive

cron脚本,自动检测执行任务:

0 */1 * * * if [[ -d /mnt/backup ]]; then rsync_tmbackup.sh /home /mnt/backup; fi

rsync time backup语法大全说明:

Usage: rsync_tmbackup.sh [OPTION]… <[USER@HOST:]SOURCE> <[USER@HOST:]DESTINATION> [exclude-pattern-file]
