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 😂

There is something to be said about CLI applications being risky by default (“rm” doesn’t prompt to ask,
rsync --deletewill do just that). But I’ve definitely slipped on the mouse button while “drag & dropping” files in a GUI before. And it can be a right mess if you move a bunch of individual files rather than a sub-folder…At least for windows, you can ctrl-z that away and it’ll handle your mouse fumble. Explorer also highlights the files after a copy so if that doesn’t work (and it was a copy action), just delete them immediately.
I haven’t used *nix for daily stuff in years but I’m sure the same abilities are there, surely.
