fb8af8c4-dd0f-470e-99c8-1c13979512b6 Posted July 17, 2011 Report Share Posted July 17, 2011 I'm seeing the message "MapError: unknown Mac error 20" in my log files when backing up a user folder on the server itself, but Retrospect appears to be successfully completing the backup in spite of it: - 7/16/11 8:38:28 PM: Copying localuser MapError: unknown Mac error 20 7/16/11 8:45:08 PM: Snapshot stored, 144.1 MB 7/16/11 8:45:19 PM: Comparing localuser 7/16/11 8:45:59 PM: Execution completed successfully Completed: 283 files, 242.4 MB, with 35% compression Performance: 372.8 MB/minute (382.7 copy, 372.8 compare) Duration: 00:07:30 (00:06:12 idle/loading/preparing) Should I be concerned?

Lennart_T Posted July 17, 2011 Report Share Posted July 17, 2011 Should I be concerned? I don't think so. I get the message all the time. Quote Link to comment Share on other sites More sharing options...

Lennart_T Posted July 18, 2011 Report Share Posted July 18, 2011 Have you had any problems performing full restore tests (assuming you've done them) after encountering this error? I have not performed a full restore, just partial. I do always verify my backups and they verify fine (except the normal reports about log files that has changed).

efde3be6-3939-426c-ab80-a288ea3cb6c8 Posted December 12, 2011 Report Share Posted December 12, 2011 I get this error every time I run a backup. Retrospect phone support blames it on the mac os and says that it has nothing to do with Retrospect. Does anyone else know how to fix this error. Being that the Retrospect logging is already difficult to read I'd like to get rid of anything that isn't necessary. Here's what the Console has to say. 12/9/11 9:40:17 PM com.retrospect.retroengine[108] #2> MapError: unknown Mac error 20 12/9/11 9:40:39 PM com.retrospect.retroengine[108] #2> MapError: unknown Mac error 20 Quote Link to comment Share on other sites More sharing options...
Daniels Posted December 13, 2011 Report Share Posted December 13, 2011 This is actually left over debug code and can be ignored. Check out kb article 9730 for more information. Quote Link to comment Share on other sites More sharing options...
