tar 备份问题

服务器上有一个目录//home/ias10g/image很大,目前300多G
在这个目录下有很多子目录,现在要求检索出每天新增的文件,然后在tar包压缩,这个命令怎么写,求教,谢谢!

    tar  增量备份  适合你不  具体查下资料

   或  -u 参数

用 find +xargs

    能具体点么?

    find /home/ias10g/image -mtime -1 |xargs tar -zcvf /home/ias10g/backup/image .tar.gz

我试过了,不行!

    你find 命令那报什么错?

   find /prod/image -mtime -1 这个命令能找出当天生成的文件,但是加了后面的命令却把所有image下的文件都打包了,要怎么修改啊?

    不清楚  原因

通过命令检索:
[ias10g@d0-lnxapp03 1]$ find /prod//prod/html_gelc_prod/image_life/001/2011/1 -mtime -1

检索出来都是今天的文件,这个没问题

怎么打包就把3号的文件都打进去了?

    你可以看看增量备份   不过用增量  需要今天重新完整备份下   -g 参数

   以后可以根据完整备份  只备份变化的!

     查资料

你的意思是我先做一个完整备份:image1.tar.gz
然后通过命令进行增量备份
tar -g /prod/html_gelc_prod/image_life -zcf image1.tar.gz
完成后image1.tar.gz 只是更新了变化的?

那么增量备份中只是包含更新的文件还说所有文件都有呢?
