Mount the windows share

[root@digweed ~]# mount.cifs //192.168.2.12/Dbackup -o user=nonono,password=nonono /mnt/ac-asus/
[root@digweed ~]# mount | grep cifs
//192.168.2.12/Dbackup on /mnt/ac-asus type cifs (rw)
[root@digweed ~]# df /mnt/ac-asus/ -h
Filesystem            Size  Used Avail Use% Mounted on
//192.168.2.12/Dbackup
                      140G  101G   39G  73% /mnt/ac-asus

rsync the share to backup dir

[john@digweed ~]$ screen -A -S backup rsync -av --delete /mnt/ac-asus/Audio/ /efserv/Backups/awcrosby/Audio/

script to automate process

#$/bin/bash
if ping -c 3 192.168.2.12
   then
        if /sbin/mount.cifs //192.168.2.12/Dbackup -o user=digweed,password=blahblah /mnt/ac-asus
          then
               echo rsync started at `date +%F_%H%M%S`
               /usr/bin/rsync --recursive --no-compress --delete --verbose /mnt/ac-asus/ /efserv/Backups/awcrosby/Dbackup/
               echo rsync completed at `date +%F_%H%M%S`
               /bin/umount /mnt/ac-asus
         else
               echo failed to mount share
         fi
   else
        echo can't ping 192.168.2.12, vandyk.dj.edm is not connectable
fi

Troubleshooting

script didn’t run because relative paths for commands were in use.. see mail from cron daemon:

/root/ac-asus-backup-2.sh: line 4: mount.cifs: command not found
failed to mount share

Backup Audio from home to work

Script

[root@jb ~]# ls -l AudioBackup.sh
-rwxr-xr-x. 1 root root 423 Aug 21 15:42 AudioBackup.sh

#$/bin/bash
if /bin/ping -c 3 edm.homelinux.net
   then
               echo rsync started at `date +%F_%H%M%S`
               /usr/bin/rsync --recursive --no-compress --delete --bwlimit=300 --progress --size-only --max-delete=250 -p -o -g -t john@edm.homelinux.net:/efserv/Audio/ /jbod/Audio/
               echo rsync completed at `date +%F_%H%M%S`
   else
        echo can't ping edm.homelinux.net, trainwreck is not connectable
fi

Note: I had to add –size-only above or it would check every file before doing any transfers.. or so it seemed. Much faster now.
