We're running OE 10.2b04 on SuSe Linux - enterprise DB lic - char only. I created a script that will run from cron - to restore selected DBs to a "testing" location after the nightly full progress backup. I was testing the script and all was running good until it got to one of the DB backup files. it started to throw the CRC error 1147. I know what that means, but the odd thing is for the date of that backup file - the prorest -vm and prorest -vf showed NO issues.

Below is the output showing that it appears to have completed cleanly: ******** BACKUP of marccls started Thu Jun 12 01:59:38 EDT 2014 289159 active blocks out of 485913 blocks in /marcs/clsbi/marccls will be dumped.

I don't fully understand why if the check of the backup on the day of the backup was clean, that it would now throw CRC errors. We will be backing up our DBs again tonight as full backups - so I expect that this issue will resolve itself. If anyone might have some thoughts on why this would/could happen, that would be helpful.
