Hi,Simon Hobson， thank you repleay. 1\ rsync,is a good sync file tools. but i think is not for me question. because: when i update some data to rrd file,the file is status is 'changed',so rsync need transfer the complete file .Is my analysis correct? so ,I think use rsync is not Reduced my netflow.
2\rrdcached,I just read it's doc.i think it maybe meet my needs. but need i write many script..... so terrible Thanks! 2012-07-17 发件人： Simon Hobson 发送时间： 2012-07-16 19:36:06 收件人： rrd-users 抄送： 主题： Re: [rrd-users] Incremental backup rrd file ccddtt wrote: >I had some rrd files more than 300M,need bakup to remote server every day. >I use VPN access the remote server,the link is very slow. >who can tell me how to incremental backup the rrd file ? > >i think maybe like this:i can back that day rrd data(not need other >day),and put to remote server,and iput the bak data to rrd file. rsync is the first tool that comes to mind.
