-641 chunk checksum error when previewing on backup?

Recommended Posts

Hi,

 

I am running Retrospect Backup Multiserver 6.5.336 on my Win XP PRO SP2 and recieve this error when doing my monthly backup. This is the second month that I do the backup and I got the same error the first time. That time I did a repair/recreate on the catalog and it workd fine afterwards. Today I got the same error when trying to backup, and I have started a repair/recreate again. As I am backing up 280 GB of data to a LTO 2 tape drive it takes a long time to recreate and I am not willing to have to do this every month.

 

What am I doing wrong?

 

best regards

Hi

 

Uninstall Retrospect and reinstall with 6.5.350 from the EMC Dantz updates site.

 

Did you know you can rebuild a catalog using only the last tape in the backup set? It will make the recatalog much faster.

 

Thanks

Hi,

 

I will try what you are suggesting. On another note; I have rebuilt the catalog now and are trying to backup, but I get an error that I need a new tape. When I try to select the tape allready in the tape streamer Retrospect tells me that "The tape cannot be added to this Backup Set. It is to different from the other media in the set." What does this mean?

Hi

 

What is your backup device? What tapes are in the drive?

Some drives support multiple media types but you can't mix them in the backup set.

 

Thanks

Hi

 

Make sure the driver for the tape drive is disabled in Windows device manager. Retrospect has its own driver.

 

Are you able to erase the problem tape in Retrospect?

 

Thanks
