DietPi backup questions

General Discussion

I have a few questions about the DietPi backup.

Is the complete system backed up?

The background to my query is:

I would like to back up a current DietPi system on which Wingibts is installed, among other things, and restore it on a new data carrier.

Specifically, it’s about a Pi 4 with an SSD connected via USB3.0.

But since this constellation causes minor problems with Wingbits(ADS-B) (I think it’s about USB jitter - please correct me if it’s wrong), I would like to copy the system from the SSD to a RasPiKey(eMMC module for the PI), clone it anyway.

If possible, this should happen without too much effort.

For this reason I was thinking of DietPi backup.

However, it should be noted that the RasPiKey has 32GB and the SSD is larger. However, without having just checked, I would say that less than 32GB is used on the SSD.

Hopefully I have been able to express my concern clearly.

I would appreciate a few tips and assistance.

maybe use a different way like Moving a running DietPi system to a USB stick/disk or an onboard eMMC – DietPi Blog

But yes, dietpi-backup is a full system backup

Thanks for the link.

That’s one way of course, but quite a lot of effort.

Ultimately, I just want to copy the running system from an approx. 100GB SSD to a 32 GB eMMC, which should then be inserted into the Pi’s SD card slot.

So I understand correctly that DietPi-Backup is a full backup and thus saves the complete contents of the SSD. This is then of course too large for the eMMC?

My simple-minded thought was to install a normal standard installation of DietPi on the eMMC and then use the backup of the SSD as a restore.

I guess this is a big mistake on my part?

I have to mention that my installation is a headless system, so there is no desktop installed, which makes it difficult to work with GParted.

Backup is saving used data only using rsync. It is not creating a 1:1 image. Therefore the backup way should work.

Gparted can be used as Linux live environment on nearly every system. Easiest is to start on a regular desktop system and connect the SSD.

At the end you would need to decide between backup option or cloning of your system. Both ways have there advantages
