No mirror device with suitable block size found SAP LOG Backup

Hi All,

since 5 days we have the issue on the SAP HANA log Backup with this Error: No mirror device with suitable block size found.

We backup the logs on 4 diffrent media. The first and the second are Disk System and the ohter two are deduplication appliance.

I check the Config on the all device and there is the same Block size, segment size and disk agent buffers.

Where can be the issue? 

Data Protector Version: 10.80

Thanks in advanced.
