Duplicity Error 5 & 22 in /proc/

Question

I've been having some problems with duplicity to backup my root folder to an external drive. The code using is:

sudo duplicity full -v4 --no-encryption --exclude /mnt/ / file:///run/media/jjonker/backup-c/

which then returns:

Local and Remote metadata are synchronized, no sync needed.
Last full backup date: none

I'm running duplicity version 0.7.17

Any clues how I can solve this? Can I simply exclude the /proc/ folder?

Thanks

Answer 1

yes,

--exclude /proc should do the trick. the duplicity man page even mentions this explicitely [1]

If you are backing up the root directory /, remember to --exclude /proc, or else duplicity will probably crash on the weird stuff in there.
