Regular backup failures.

[Former Member]

hello all,

I am getting a backup failures every 14th calendar day of the backup schedule.

the error is..

BR278E Command output of 'dd bs=32k conv=sync if=D:\ORACLE\EP1\SAPDATA6\BTABD_1\BTABD.DATA1 of=/dev/nmt0':

dd: unable to initialize ASPI manager

dd: using NT tape support

17600+1 records in

17601+0 records out

dd: Data error (cyclic redundancy check).

BR280I Time stamp 2006-11-12 20.03.33

BR279E Return code from 'dd bs=32k conv=sync if=D:\ORACLE\EP1\SAPDATA6\BTABD_1\BTABD.DATA1 of=/dev/nmt0': 0

BR222E Copying D:\ORACLE\EP1\SAPDATA6\BTABD_1\BTABD.DATA1 to/from /dev/nmt0 failed due to previous errors

BR280I Time stamp 2006-11-12 20.03.38

BR317I 'Alter tablespace PSAPBTABD end backup' successful

BR056I End of database backup: bdtxujdy.ant 2006-11-12 20.03.33

BR280I Time stamp 2006-11-12 20.03.38

BR054I BRBACKUP terminated with errors

it happend today but will again go on error free for next 13 days and on 14th day it will again give the same error.

I think there is some problem in ASPI manger when it calls the device to be initialized.

kindly help in resolving this...

precise and good answers will be rewarded accordingly.

thanks

Hi Saurabh,

Usually <b>Data error (cyclic redundancy check).</b> means that one of your tapes is damaged or corrupted, this could happen every 14 days if you are cycling the tapes...

Hope this help!

hi juan

thanks for the answer

just a quick question

i found that the backup label EP1B007

is having problem everytime it is being scheduled for backup.

now does it means that the tape being initialized as EP1B007 is curropted...then in that case should i a back this tape up and use the new tape under that label..

what do you suugest...

thanks

Hi Saurabh,

You need to remove this tape and replace it with a new one, youre not going to be able to do a backup of the tape because the tape is gone, just remove the tape and replace it with a new tape with a new label (or the same one if its possible)

Hope this help!
