----------------------------------------
#!/bin/sh
cd /var/BACKUP
tar -cvf cvsroot.tar /var/cvsroot
#tar -cvf cvsroot.tar cvsbackup.txt
gzip cvsroot.tar
/usr/bin/scp cvsroot.tar.gz root@192.168.1.100:/BEGANTO_BACKUP/cvs/cvsroot-$(date +%Y%m%d-%H%M%S).tar.gz
echo "Backup of cvsroot has been copied in form of .tar.gz file"
mv cvsroot.tar.gz cvsroot-$(date +%Y%m%d-%H%M%S).tar.gz
mail -s "CVS server backup" yogendra.rawat@beganto.com < cvsbackup.txt


Please help.

do you have to enter a password to connect to the other machine? which user runs the cronjob? which user runs the script manually?


Greetings,

This will allow your server not to authenticate in the backup server:

Do this in the machine that has your cronjob

mkdir –p /root/.ssh
chmod 0700 /root/.ssh
ssh-keygen –t dsa –f /root/.ssh/id_dsa –P ''

then
copy /root/.ssh/id_dsa.pub to the backup server

then do this in your backup server
cat id_dsa.pub >> /root/.ssh/authorized_keys2
chmod 0600 /root/.ssh/ authorized_keys2
