backups for SD card disk image? that don't take up tonnes of space and can be rolled back? in c/[email protected]

hmmm I think this is a bit beyond me; at this point I don't want to create an additional side project. I might learn about the more modern spiffy file systems in a few years.

the clonezilla website clonezilla.org says

Differential/incremental backup is not implemented yet.

Borg backup has insane deduping. The first time I used it I thought it was broken because of how much smaller the backup was compared to the original. I used it with vorta GUI.

I am not sure how to combine the task of making a disk image with backing up with borg either on the command line or via one of the GUIs?

Thanks I will look at rdiff. I am not sure if rsync is able to "see inside" the *.img files to discern the individual files. If it can then it would be helpful because I could just re-write the same file over and over again and keep backups using rsync or any of the various rsync-derrived tools?

The filesystem will be cold at time of back up because I will need to shut it down, remove the card from the console and put it into my computer's reader so no worries about that.

backups for SD card disk image? that don't take up tonnes of space and can be rolled back? (lemmy.world)
 

I would like to make manual backups of an SD card as a disk image so that it can be easily recreated when needed. I'd like to keep a few versions in case there is a problem I didn't know about, it can be rolled back.

How can I do this incrementally, or with de-duplication, so that I don't have to keep full copies of the complete SD card? It's very big but most of the content won't be changing much.

It's for MiyooCFW ROM which is on FAT 32-formatted micro SD card.

Thanks for your help! Also let me know if I am going about the problem in a wrong way.
