What did 'more info about this error' link go to? The URL please.
Check to see if there is a directory in /moodledata/temp/backup/ that was the attempt to extract.
It will be a long directory name.
cd into that directory.
Then ls -l. Is there a files.xml file there? There shouild be. It's the 'roadmap' for restoring file resources that were in the backed up course.
In files.xml, there should be a reference to the real file located in the 'files' directory of the un-archived files ... the 04/047ebuchmore reference.
The files, will not have humanly recognizable names ... but in looking at files.xml one can see the meta data of all the files ... filename reference in the XML.
Do you re-call IF in those courses there were links to files where the 'alias' was checked? I know that's asking a lot of one's memory (I myself, can't remember that either!).
