Curious on execution errors?


Recommended Posts

I frequently get the following types of execution errors reported in log. I'm curious as to what they mean.

 

Thanks for any links to where I might find the answers.

 

FWIW: My system: OS X 10.4.5, Retrospect Backup 6.1.126, backing up to external Firewire hard drive.

They mean that your OS X computer is happily running during the backup process.

 

- Retrospect first scans all the files in your Source, and notes things such as their size and date.

 

- Then Retrospect writes all these files to your Destination media.

 

- Then Retrospect goes back and reads in the files it just wrote, and compares the copies against the original information. Any differences are noted.

 

Things such as log files are constantly being written, so it's normal for the new files to be larger and newer then the originals.

 

As for the .gz files, it's likely that your backups are occuring at the same time that OS X is doing housecleaning tasks with the system logs. It all looks normal and expected.
