If you use rsync to do an incremental backup of a partition and you forget to mount it, such as:
Code: Select all
rsync -ai --progress --delete /mnt/sda8/ /mnt/sdb3it will DELETE all the files on the backup. 
Mount it and run it again and it will copy back the 40 gig of stuff it just deleted. 
backmeup.sh
Code: Select all
#! /bin/bash
:<<'[#####]'
rsync to /mnt/sda8
rsync -avu --delete "$SOURCE" "$DESTINATION"
[#####]
if [ -z "$(mount | grep -i /mnt/sda8)" ]; then
zenity --info --timeout=10 --title="Sync2Backup" --text="sda8 not mounted .." &
exit
fi
#-- rsync ----- From: ___________ To:
rsync -avu --delete /stuff/to/backup /mnt/sda8/backup/destination
sync
echo "Backup Complete $(date)" > $HOME/sync2backup.out
notify-send 'Sync Complete!' 'Have a nice day!'
backmeup.sh
