Hi Experts,

We need your help.

We have ECC 6.0 PRD system on linux SLES11 sp1. We are facing issue while taking tapedrive online backup. We tried with OS backup on tapedrive and it was successful.

While doing the brbackup following error occurs :

Hello Pramod,

Error is not clear to me, but one thing I would like to suggest (not related to error) -

I see - BR0112I Files will not be compressed, it is better to put compression ON. I think this needs to be edited in same profile file where you have edited other parameters like 'backup device type'

Thanks

Hi,

We had turn ON compression mode. But after that we are facing another issue.

Hi,

I think you should use

compress=hardware

Are you sure, your tape-device is capable of using 64k blocks?

might be worth to try either 32k or 128k ???

Hi Experts,

Thanks for support,

Issue has been solved. There was a problem with BR tools. We have updated BR tools patch. Now we are able to take SAP online tape backup.

Thanks and Regards,
