RIP my photos from 2017 and contacts from 2005

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'm just impressed an SD card in a Pi lasted since 2017 without losing all your data on its own.

For the future the general guideline is 3 copies of your data at minimum, so definitely set up some backups.
