点滴之间 聚沙成金

一个使用tar实现对目录作增量备份的bash脚本

#!/bin/bash
#program:
#  auto backup the folder $to_backup
#        to $save_to
#  History:
# 2012/11/28  yqf First release

# do NOT change the variable $filename
#  except you REALY know what you are doing exactly
filename=`date +%Y%m%d_%H%M%S`

# sample
# ##whitch folder you want to backup, full path (start with "/")
#to_backup="/var/www/html/foo"
# ##where you whant to save the backup files,folder, MUST end by "/"
#save_to="/var/www/backup/foo/"
# ##the incremental file, file name, full path
#incremental_file="/var/www/backup/incremental_file/foo.incre"
#
#tar -g $incremental_file \
# ## each files or folders that no need to backup, (ingore),
# ##    [Careful] without end slash even folder
#  -C $to_backup \
#  --exclude data/cache \
#  --exclude data/tmp \
#  -cpjf $save_to$filename.tar.bz2 .
# sample end
#
# mysite.com
to_backup="/var/www/html/mysite/html/"
save_to="/home/myhome/backup/mysite/"
incremental_file="/home/myhome/backup/incremenntal_list/mysite.increment_file"

tar -g $incremental_file \
  -C $to_backup \
  --exclude data/static_cache \
  --exclude data/templates_c \
  --exclude data/templates_cache \
  --exclude data/cache \
  -cpjf $save_to$filename.tar.bz2 .
