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 know I’m going to get down voted for this but this would be almost impossible to fuck up with a gui. Yet people insist that writing commands manually is superior. I’m sorry for your loss.
Fair enough.
CLI is not about ease to begin with, it is about versatility.
There is something to be said about CLI applications being risky by default (“rm” doesn’t prompt to ask,
rsync --delete
will 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.
To play devil’s advocate, tab completion would have also likely caught this. OP could have typed /mnt/t<Tab> and it would autofill temp, or <Tab><Tab> would show the matching options if it’s ambiguous.
