who can do that with out copy all files ?

example:

srv1 /tmp/data1, data2 etc.. copy svr2 /tmp/data2 the data2 is data new for this day

Thank You !!!

Looks like rsync will be best suited for this job...since it copies only new and changed files instead of all thus saving network bandwidth. See the man page for rsync(1).

cheers!

Or use the built in command rdist:

Here's how I sync /home/bwpadm user to DR site:

From cron:

15 01 * * * /app/admin/drp/update-binaries.sh >/tmp/update-binaries.cron 2>&1

#! /bin/sh

# Keep the DRP copy of the bwpadm up-to-date.
# Currently the files are in:
#
# /home/bwpadm/DR
#
# See the rdist(1M) distfile for a list of exclusions.

DRPDIR=/app/admin/drp
DRPHOST=svr102

HOST=`/usr/bin/uname -n`
mount | grep /home > /dev/null 2>&1
if [ $? -eq 0 ]
then
/usr/sbin/vgexport -p -s -v -m /home/bwpadm/DR/vg10.map /dev/vg10
( su - bwpadm -c "rdist -f $DRPDIR/distfile bwpadm"; ) 2>&1 |\
tee $DRPDIR/drp.log 2>&1 |\
mailx -s "bwpadm DRP rdist output" sysadm
fi

# cat /app/admin/drp/distfile
BWPDR = ( svr102 )

#
# File systems to be copied over to the DR host.
# Don't use -R in install - so as not to remove files on destination host
BWPADM = /home/bwpadm

bwpadm: ( ${BWPADM} ) -> ( ${BWPDR} )
install -w ;

Why can not you use NFS for this requirement simply?

Or else write a script to find files which are new today and put into a file called /tmp/files2copy-svr2.

First copy the file and then get the files available in that file.

Else use rsync for this.

Hi,

you can use the find command with -ctime, -mtime, atime parameters then copy it to the other server using scp/rcp/ftp/sftp etc...

your command would look like this.

find /tmp -name "data?" -mtime +1 -exec scp {} user@svr2:/tmp/{} \};

good luck ..hope this helps..
