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 😂

Fuck up #1: no backups

Fuck up #2: using SD cards for data storage. SD cards and USB drives are ephemeral storage devices, not to be relied on. Most of the time they use file systems like FAT32 which are far less safe than NTFS or ext4. Use reliable storage media, like hard drives.

Fuck up #3: no backups.

Would an SSD be any better than a pen drive or should it be stored on spinning rust?

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
