Pinephone OS Backups (System Images)

[ThrillGates]

(Maybe some Linux app suggestions, I no longer have anything Windows on my property)

I think the dd command (might need a sudo) should be sufficient to backup with a Linux machine. Set the source to your SD card or eMMC, and the output to wherever you want to save (/backupdir).

1. Find the device name of your eMMC or SD card. My eMMC shows up as 'mmcblk2' on the phone itself.

Code:

lsblk

2. Check the lsblk output to see if any partitions on your source device are mounted. Unmount them using their mount points as a reference. For example, to unmount the partition /dev/sdb1 with the mount point /media/thumbdrive:

Code:

sudo umount /media/thumbdrive

note that the command is 'umount' not 'unmount'

3a. To create an uncompressed image (replace 'sda' with your source device)

Code:

dd if=/dev/mmcblk2 of=/backupdir/filename.img

3b. To create a compressed image with gzip

Code:

dd if=/dev/mmcblk2 | gzip -c >/backupdir/filename.img.gz
