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 😂

    Sorry to hear, I feel you:

    I wanted to delete all .m3u-files in my music collection when I learned:

    find ./ -name "*.m3u" -delete -> this would have been the right way, all .m3u in the current folder would have been deleted.

    find ./ -delete -name "*.m3u" -> WRONG, this just deletes the current folder and everything in it.

    Who would have known, that the position of -delete actually matters.
