I think Raspbbery Pi is a great device and I love how easy and fun is to create IoT projects using it. I am using Raspberry Pi at my vacation house and also at my parents summer house. It is monitoring remotely the temperature, the voltage of batteries connected to the wind-turbine and solar-panels and controlling the alarm system and some relays that are starting and stopping different appliances. <\/p>\n\n\n\n

These projects started for fun and curiosity, but as time goes by, they seem to become a very important component of the house itself, whithout which, it is difficult to imagine now the existence of the house. <\/p>\n\n\n\n

Therefore we have to keep this component as safe as possible and to have a backup in case something goes wrong. Because, in my case, it’s almost impossible to do a backup of the SD card locally, I would need a remotely backup solution.

So let’s see how can we create it. I’ll use a Linux VM as local computer from where I start the connection.<\/p>\n\n\n\n

Step one – Check SD Card <\/strong> <\/h3>\n\n\n\n

Connect to RPi from Linux VM local computer:<\/p>\n\n\n\n

 root@kali:~# ssh pi@192.168.1.223  <\/pre>\n\n\n\n
Once in, use this command to list block devices :<\/p>\n\n\n\n
pi@raspberrypi:~ $ lsblk -p\n NAME             MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT\n \/dev\/mmcblk0<\/kbd>     179:0    0 29.8G  0 disk\n \u251c\u2500\/dev\/mmcblk0p1 179:1    0 42.9M  0 part \/boot\n \u2514\u2500\/dev\/mmcblk0p2 179:2    0 29.8G  0 part \/<\/pre>\n\n\n\n
 Note block device marked above, then disconnect from RPi. <\/p>\n\n\n\n
Step two – Backup your Raspberry<\/strong><\/h2>\n\n\n\n
 Start the backup  from Linux local computer  using this command :<\/p>\n\n\n\n
 root@kali:~# ssh pi@192.168.1.223 \"sudo dd if=\/dev\/mmcblk0 bs=1M | gzip -\" | dd of=~\/Desktop\/pibackup.gz\n ..............................\n pi@192.168.1.223's password: <\/pre>\n\n\n\n
add the password of the RPi and the backup will start. <\/p>\n\n\n\n
