Daughter's Backup Failed :-(
Hi Dave,
My daughter's Mac blew an error during this week's backup and I just now noticed. I tried to run it again, but the same error occurred. I copied the last few lines from the log in hopes you might have some idea what's up. | 01:21:57 AM | Info | Re-copying: /private/var/db/diagnostics/Persist/00000000000004df.tracev3 | 01:22:12 AM | Info | Unable to read source file /private/var/db/diagnostics/Persist/00000000000004df.tracev3 due to error: 5, Input/output error | 01:22:12 AM | Info | Error copying /private/var/db/diagnostics/Persist/00000000000004df.tracev3 to /Volumes/Tumnal Clone/private/var/db/diagnostics/Persist/00000000000004df.tracev3 of type 8 due to error 5 | 01:22:12 AM | Error | SDCopy: Error copying /private/var/db/diagnostics/Persist/00000000000004df.tracev3 to /Volumes/Tumnal Clone/private/var/db/diagnostics/Persist/00000000000004df.tracev3 of type 8 due to error 5 | 01:22:13 AM | Error | : Input/output error |
Yes, as the log indicates, it's a read error on the source. It looks like a failing drive.
Use Finder's Go To Folder command to open /private/var/db/diagnostics/Persist Once there, delete 00000000000004df.tracev3, empty your trash and try the copy again. |
Thanks for the quick response, Dave. That's what I was afraid of. SMART status showed all was well, but SD! is usually a better, if unwanted, canary in the coal mine.
Going forward is that how I should interpret that line of the log. It seemed somewhat generic in that I assumed there might be multiple reasons for an "Input/Output" error. I'm trying to delete the offending file now and see what happens. |
In the future, send the log with the "Send to shirt pocket" button and I can do some additional analysis that way...
|
Will do...
And I deleted the file as you suggested which did allow the backup to complete, so thanks for that! I suspect her iMac is headed for a full disk failure at some point. It's pretty darn old so not sure if a repair makes sense :-( |
