Replace your rsync command (assuming that you want to sync server1 with local server2)
Code:
rsync -avz server1:/mail server2:/mail
with (type command on server2)
Code:
rsync -avrR --links --rsh=/usr/bin/ssh server1:/mail :/mail
To avoid password prompt you need to setup ssh-keys, so on
server2 type following commands:
Code:
ssh-keygen -t rsa
ssh you@server1 "mkdir .ssh"
scp .ssh/id_rsa.pub you@server1:.ssh/authorized_keys2
Now you can login to server1 from server2 without password. Now setup cron job using following script (save script on server2):
Code:
#!/bin/bash
MASTER="server1"
DIR="/mail"
LDIR="/mail"
SSH="/usr/bin/ssh"
rsync -avrR --links --rsh=$SSH $MASTER:$DIR $LDIR
Cron job
Setup cronjob using following syntax:
Code:
1 18,19,20,21,22,23,0,1,2 * * * /path/to/script.sh
Script.sh will run at 6:01pm, 7:01pm, 8:01pm ... 2:01am
