Veritas System Recovery adding cloud storage issue

Hi all,

I would like to add S3 compatible cloud storage as my backup destination.

Firstly, I have created a cloud instance as per https://www.veritas.com/support/en_US/doc/38007533-136670227-0/v132418412-136670227

Since I dont have Certificate Authority (CA)-signed certificate, I have to use SSL: 0 (disabled).

However, when I tried to add cloud backup destination, in the packet received from the cloud library I see this message: The authorization mechanism you have provided is not supported. Please us AWS4-HMAC-SHA256

Unfortunately, on the cloud library (netapp) there is not possible to change the configuration.

Do you think that there is any workaround to the issue in such situation?

Thanks for your opinions.

Re: Veritas System Recovery adding cloud storage issue

I got more info.

It looks like that the message "The authorization mechanism you have provided is not supported. Please us AWS4-HMAC-SHA256" means AWS signature version 4.

------------------------------
<Authenticating Requests: Using the Authorization Header (AWS Signature Version 4)>
https://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-auth-using-authorization-header.html

AWS4-HMAC-SHA256
The algorithm that was used to calculate the signature. You must provide this value when you use AWS Signature Version 4 for authentication. The string specifies AWS Signature Version 4 (AWS4) and the signing algorithm (HMAC-SHA256).
------------------------------

On the other hand, VSR support only version 2 as below.

Veritas System Recovery supports only signature Version 2 for the S3-compatible cloud storage.

Please check the signature version for your s3 compatible device.

Re: Veritas System Recovery adding cloud storage issue

That's exactly how it is. It looks that the issue boils down to the version 2 or 4 used by the software.

Thanks for the post with guidlines for installation minio cloud compatible storage. I did manage to set up this cloud storage as the destination for backup. Actually, I used minio as part of the freenas software and just disabled https by renaming cert files. It works brilliantly.

I published an article for this issue. And linked 100044854 and 100049556 each other.
