Description: Ubuntu 10.04.1 LTS

"Permission denied". Can you create a folder on the target device normally using the file manager?

[Mark Preston (emarkpreston)]

Yes, I can create a folder. And I put a .jpg in it, then deleted the .jpg. Then I shift-deleted the folder. All seems OK there.

Well, the error is relatively clear. GIO gave a "permission denied" error while essentially executing:

ls /media/2323a609-2d93-4b52-aaa5-9b0bb0fab7e2

So... Why? When your external drive is mounted, I assume that folder is safely listable. But when it's not mounted, I assume the folder is owned by root and can't be listed. Is that right?

I notice that your file/type setting is "normal" instead of "volume" like I would expect. Did you ever manually edit that?

[Mark Preston (emarkpreston)]

I apologize for having to ask, but:

I have no idea of how to determine the permission (of a device) whether mounted or unmounted. That's way beyond my geek-eee-ness. Please help.

As for "normal" vs. "volume" I didn't knowingly change this. That drive was formatted using GParted. As it is an external drive, I felt save in changing the file system, etc. without being in LiveCD mode. That is, I formatted the external drive while Ubuntu was running.

Again, I'm sorry for not being able to offer more help.

What I'd like to see is the result of:

ls -ld /media/2323a609-2d93-4b52-aaa5-9b0bb0fab7e2

and

ls -l /media/2323a609-2d93-4b52-aaa5-9b0bb0fab7e2

after you unmount the drive.

[Mark Preston (emarkpreston)]

Thank you for your thought about me problems. About 1 month ago, I blew
up my OS (Natty). I had to do a re-install and no longer have a device
with the name you ask about.

Terminal output of ls /media is:

256-MEG 5c9a6ed1-2994-4549-b87c-735f94f1cb55 8-GIG TV

Will there be a time when DejaDup will preserve file and extended file
attributes in a backup? After blowing up my OS, I made a TAR of
the /home. On the reinstall of the replacement Natty, however, no
restore was required. Ubuntu found all the configs, and other settings
so other than re-installing Adobe Reader and other lost apps, it was all
working as before. It just gets better and better.

Thanks for your time and effort and let me know if I can help the Deja
project. I still like the program.

Deja Dup should already be preserving file attributes.
