Description and Usage

This script uses rsync and ssh to backup directories specified on a secondary file to their corresponding destinations.

Files:

Bk.script

The actual backup script, that does the dirty work.

Bk.source

Script containing two arrays. The SOURCES array, which contains the path strings to the directories on that server that will be backed up, and the DESTINATIONS arrays, which contains the corresponding destination strings in the form "serve:path". The sources and destinations are matched by their index on the arrays. There is also a USER variable that needs to be set. The file is well commented.

Ideally the dcdBk.script file should be in the crontab (as a cron job), and of course be executable.

Bk.script

#!/bin/bash

source ./Bk.sources

for (( i = 0 ; i < ${#SOURCES[@]} ; i++ ))
do 

    source=${SOURCES[${i}]}
    destination=${DESTINATIONS[${i}]}

    index=$(expr index $destination ':')
    destination_server=${destination:0:$(($index - 1))}
    destination_directory=${destination:${index}}

    comando='[ -a ${destination_directory} ]'

    if ! ssh ${USER}@${destination_server} eval $comando; then
         ssh ${USER}@${destination_server} mkdir -p ${destination_directory}
    fi

    if rsync --append-verify -rutq ${source}/ ${USER}@${destination_server}:${destination_directory}; then
        echo `date '+%Y%m%d'` >> ${source}/backup_time.log
        rsync -utq ${source}/backup_time.log ${USER}@${destination_server}:${destination_directory}/backup_time.log
    fi

done

Bk.sources

#On the SOURCES array there should be the path to the folders to be backed up, the corresponding destinations should be on the DESTINATIONS array.

#It's important to observe that the path strings should always end with an '/', otherwise rsync will behave badly.

#The destination strings should be in the form "server:path".

SOURCES=(	"/home/erica/laminarinase/2HYK/"
		"/home/erica/laminarinase/M133C/"
	)

DESTINATIONS=(	"foo.iqm.unicamp.br:/store7/jorge/laminarase/2HYK/"
		"foo.iqm.unicamp.br:/store7/jorge/laminarase//M133C/"
	     )

#This is the user that will ssh on the destination server. It should poses an public key on that server, so that it wont be necessary to type in the password.

USER="Foo"
