I recently decided to replace the SD card in my Raspberry Pi and reinstall the system. Without any special backups in place, I turned to rsync to duplicate /var/lib/docker with all my containers, including Nextcloud.

Step #1: I mounted an external hard drive to /mnt/temp.

Step #2: I used rsync to copy the data to /mnt/tmp. See the difference?

Step #3: I reformatted the SD card.

Step #4: I realized my mistake.

Moral: no one is immune to their own stupidity 😂

Unlesa you did a full zeroing format the info might still be available. There was an applicarion that attempts to rebuild the partition / Filesystem from left over meta data or inode info. I forget the name unfortunately. Normall the strings command will get your photos but probably not if they were in a docker image database.

Testdisk and photorec? It's saved me heaps of times.

Those are good for sure. And maybe it was testdisk. There was one that just undeleted the partition table delete. as long as new data had not been written everthing would be intact
