Script for replication

[coollllllllllll]

Hi ,

Am looking for  a script to replicate files between DC n DR
We have s structure say /test1  where many subfolders are there and the sme gets updated , can i transfer only the updated contents from Dc to DR via script say running in cron evry 15 min.

I tried newer option , but it just chokes the B/W , any other method to replicate the same.

we have a link of 45 Mbps

Ex :  any file gets updated in DC /test1/temp.txt should be ftp'd to  DR /test1/temp.txt

both hpux servers 11iv2.
rx2660
4c/16gb

Have you looked into using rsync?

With find? This should be the minimum number of files to copy.

(What is B/W, bandwidth?)

You could also gzip the files before copying them.  If there are lots of small files, you could also tar them up.

Hi Dennis,

Can i use rsync for the wholemount point.

Suppose my application is writing in a /test/wer/1 directory and many other subdirectory too.

Is it fine if i just do the following and put it in cro afetr evry 15 min.

 rsync -zrv --include="*.*" server1:/test/wer/1  /test/wer/1

Yes.  Or many of them.

You want to pull from server1?  And you only want to include files with a "."?

Thanks Dennis,
rsync works like a charm
