no Backup on SBS2011 to external 3TB USB3 HDD

Thread needs solution

Hello
we had a lot of SBS2011 with ABR11.5, Backup to ext. 3 TB USB HDD.
This Server now doesn't Backup run, The Server runs in Bios mode with Raidcontroller, after connecting a ext. 3 TB HDD the Job Fails with Err 41 etc., we had check the Solutions in the inet
but nothing will help, after we had taken a ext. USB hdd with 1 TB the Image runs without Problem.
The ext. 3 TB is a GPT-Part to get one big 3 TB Partition. Is this maybe the Problem that the combination Server als Bios (not as UEFI) an the ext. is a GPT ? to Change the ext. HDD to a MBR Disk with a 2 TB Partition has no changes. The Image Ends with Err.
Writing the Image to a internal raid Partition is possible, only to the ext. 3 TB Disk not

Any ideas
best regards
Andreas

Hello CSD-AD,

welcome to Acronis Forum!

I will be glad to assist you.

As far as I understood, backup fails if you choose an external 3TB disk as a target.

Could you please post here the exact error message that you receive after backup fails?

Thank you in advance!
