The backup log shows course as unfinished, (see unfinished.jpg file attached).
If I go to the course in question, I see the following details under course backups. (see negative file size.jpg). -457044577 bytes
if I try to download the negative size file, I get "500 server error - there is a problem with the resource you are looking for, and it cannot be displayed."
I am also not able to restore the course using the neg size back up file. If I try to download a file from another course that is (940MB) than the , it downloads no problem and can be restored.
Any suggestions as to what is causing this issue ? I have tried deleting the negative files and letting the back up run again. It says backup completed successfully. but file size still shows as negative. not sure what else to do. It seems to only be affecting the one course right now.
