What does this alert mean?

[itasara]

I backed up an external drive and got a message that one file could not be backed up because there permissions for ALC type was not allowed or denied, or something like that. What does this mean? And I will assume that the rest of the files got backed up? I was using option to back up newer files.

Please send in your log using the Send to shirt pocket button and I'll take a look, itasara.

Unfortunately, I can't do that. I decided after I assumed that most of the files o that drive were okay, I moved them to another drive and then erased the drive. So I don't have the last log that I know of.

OK - I don't really have enough information to be able to diagnose the problem. If it happens again, please send in the log.
