inotify-tools + rsync 实现文件自动同步备份

公司图片服务器以前以nfs挂载在各台php-fpm服务器下,最近因为部分fpm服务器迁移到aliyun,远程挂载效率低下,为了本地不修改代码,又可以达到不低,所以想到了inotify + rsync。

#!/bin/sh

# get the current path
CURPATH=`pwd`

inotifywait -mr --timefmt '%d/%m/%y %H:%M' --format '%T %w %f' \
-e close_write /tmp/test | while read date time dir file; do

       FILECHANGE=${dir}${file}
       # convert absolute path to relative
       FILECHANGEREL=`echo "$FILECHANGE" | sed 's_'$CURPATH'/__'`

       rsync --progress --relative -vrae 'ssh -p 22'  $FILECHANGEREL usernam@example.com:/backup/root/dir && \
       echo "At ${time} on ${date}, file $FILECHANGE was backed up via rsync"
done
