If you want to compare two directories using rsync.

Some time ago I’ve been moving from one hosting provider to another. I had to transfer the files from A to B and used rsync for that. But unfortunately rsync command was crashing due to some timeouts. So I’ve found really nice script for auto restore.

rsync-auto.sh

#!/bin/bash

while [ 1 ]
do
    /usr/bin/rsync -avz --progress $1 $2
    if [ "$?" = "0" ] ; then
        echo "rsync completed normally"
        exit
    else
        echo "Rsync failure. Backing off and retrying..."
        sleep 10
    fi
done

Execute

rsync-auto.sh SOURCE DESTINATION
