Backing up your device

Check which device is the Librem 5:

usr@domain:~/Backups$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS sda 8:0 1 29.1G 0 disk ├─sda1 8:1 1 465M 0 part /media/usr/<ID> └─sda2 8:2 1 28.7G 0 part └─luks-<ID> 252:2 0 28.6G 0 crypt /media/usr/<ID> <Other Items> 

In mine (and in most devices) it is sda. If yours is different, you can just change the following snippets to use your device's name.

First unmount any partitions: I think you may have to wait if the device is busy or still being mounted.

sudo umount /dev/sda* 

Then create a backup:

sudo dd if=/dev/sda of=sda-librem5-backup.img status=progress

And tada!!! All done :)
