[steven_bier]

Hello,

Database Release is on 7.5.0 32 build

Backups work fine, but when i check my backup via Database Manager - Check - Backup

this error is shown.

The Blockcount is correctly set to 64 !

Where ist my Problem ?

I have test it with serveral Backups, every time with same error Message.

Hello Steven,

The information is not enouph to get clear on your problem.

1) I could reproduce the reported error with the following scenario, for example.

• Create the medium with default block size, dbm command:

backup_media_put "test" "test" FILE DATA 0 8 NO NO "" NONE

• create the databackup

• check my backup via Database Manager - Check - Backup

-> Check a medium < create the medium with block size 64 pointed to the "test" backup file >.

Dbm command: backup_media_put "test1" "test" FILE DATA 0 64 NO NO "" NONE

• Run Backup check using medium "test1" =>

Got error "-24988 SQL error [backup_restore_check "test1" DATA]; -903,Host file I/O error, blockcount mismatchu2026"

The error occurred due the difference of the block size settings in the defined mediums.

2) "Where ist my Problem ?

I have test it with serveral Backups, every time with same error Message."

To get clear on your Problem it's will be helpful to see the following information:

• Messages in dbm.prt, knldiag, knldiag files;

• Please post dbm.prt & dbm.mmm files;

• Param history & backup history information;

• What is the version of the Database Manager on your PC?

• What is the DBM user of your database?

• May be, additional information will be needed ...

3) Are you SAP customer?

If you are SAP customer => Did you create the OSS SAP ticket, where this issue was reported?

Thank you and best regards, Natalia Khlopina
