Auto Pi Backup to NAS

How to backup your PI as an image to a NAS.

Set up CIFS Mount

Mount CIFS (common internet file system)

sudo mount -t cifs //192.168.0.181/PIBackup /media/sd/backup/ -o user=user

Mount on Boot

Using fstab is a bit risky, instead add a script in say root eg:

mountNAS.sh:

add the mount command with password={pwd}

sleep 30 
# time for network to come up 
mount -t cifs //192.168.0.181/PIBackup /media/sd/backup/ -o user=user,password=pwd

then crontab -e and @reboot /root/mountNAS.sh

chmod +x mountNAS.sh

crontab -e
@reboot /root/mountNAS.sh

Backup

Framps tools

Using the following:

https://www.linux-tips-and-tricks.de/en/raspberry/303-pi-creates-automatic-backups-of-itself/

Once downloaded run

raspiBackupInstallerUI.sh

Chose dd/windows rather than rsync.

See: https://www.linux-tips-and-tricks.de/en/quickstart-rbk/

Cron is here:

/etc/cron.d/raspiBackup

# 
# Crontab entry for raspiBackup.sh 
# 
# (C) 2017-2019 framp at linux-tips-and-tricks dot de 
# 
# Create a backup once a week on Sunday morning at 5 am (default) 
# 
00 03 * * 0 root /usr/local/bin/raspiBackup.sh

The above does a weekly backup on Sunday at 3.00 am.

Manually test:

nohup /usr/local/bin/raspiBackup.sh &

Restore

For DD backups the Windows32DiskImager can be used to restore the backup. A backup can also be restored with Raspberry Pi.

TAR or RSYNC backups have to be restored with Raspberry Pi.

For mac you can use the following to restore the image to SD card:
