Encryption: Veeam or Bitlocker?

[bunger]

I have a requirement that my backups need to be encrypted.

My backup storage device is a direct-attached-storage unit ( SAS ) and my backup server is 2012 Standard.

To encrypt the backups, I could either enable Bitlocker on the DAS drive - OR - enable encryption within Veeam itself and leave the DAS unencrypted. I am having a hard time deciding which route to take.

Bit locker would preserve the full storage space on the DAS and should be transparent, but if I ever detach the DAS and move it to something else for recovery, I am going to run into issues as it will be encrypted.

Veeam would allow the DAS to stay unencrypted, so I could move it if needed, but I am thinking the size of encrypted backup files will be larger than if they were not encrypted. Is that a correct assumption?

Which would be the preferred route for this solution?

Thanks in advance!!

The difference in backup sizes should be negligible. There is nothing preventing you from running test backup to confirm it, though. Thanks.
