Symptom

You are performing system copy using HANA backup and recovery. And it fails with the following error :

RECOVER DATA finished with error: [448] recovery could not be completed, volume 1, reached log position 0, [110025] BackupExecutor: exception 3020049: Page 0x3ffcL has wrong owner: Expected [filemap] but found 0xffffffffffffffed-EID; $patype$=Default

And in nameserver trace, you could see the following error, and seems that the data backup file is corrupt.

But by using the hdbbackupcheck according to note 1869119 - Checking backups with "hdbbackupcheck", the check result is successful. This means that the backup file is not corrupt and can be used.
