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 😂
I think everyone has done this. I know I have. I believe I used dmda to recover all my photos back. Unfortunately I lost all the metadata for about 3000 photos. It took years to manually retap and redate them all but at least I didn’t lose them forever
