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 ๐Ÿ˜‚

SD cards and pen drives are (usally) made from lower quality, cheaper nand (the little memory chips that store the data) and also lack health monitoring, that being said ssds can and do die so it's important to have backups
