I'm a mostly-noob with Ubuntu. Running 14.04 LTS 64-bit.
I use Déjà Dup to backup my entire Home folder, daily, to an external 32GB SanDisk USB flash drive.
But after every backup, Déjà Dup tells me:
"Could not back up the following files. Please make sure you are able to open them."
The folder that won't backup: "/home/username/.config/nautilus-actions"
Question: Should I worry about this? Is it important that I successfully backup this folder/file? If so, then how do you advise? If it isn't important, then what am I losing by not backing it up? And in that case, how do I configure Déjà Dup so that it stops annoyingly telling me that it failed to backup this folder/file?
(I already tried changing the folder's/file's permissions to make it owner-executable, assuming that would give Déjà Dup access. But after I did that and logged back in, I got an error report. I'd apparently screwed with my system. Don't know how to look up the specifics of that error report — if that info would help, could you advise me on how to retrieve it?)
Thanks a billion.
