Restoring Tapes from Azure Blob Archive tier storage

Postby dgbegfb » Tue Mar 31, 2020 12:07 pm

Hi guys,

I started using VTL 8.0 13481 free license with Veeam and Azure blob storage. I've managed to upload some tapes to Azure archive tier storage directly and restore from there. Doing that I found out that StarWind VTL during rehydration azure archive tier changes blobs tier to "cool" and that is non cost efficient way in this case because after that I have to pay either for early deletion from cool tier or for deletion and read operation from cool tier.

Could you please change the logic of the restoration process from Azure in the part of rehydration to much more cost efficient: "archive tire" -> "hot tier" or to add additional adjustment to the tape restoration?

Greetings,

Thank you for your question. Let me clarify that with our R&D team.

I believe that is the way StarWind Cloud Replicator works. Transferring from archive straight to hot costed more than moving data to cold tier as intermediate when the solution was designed.
Delegated to R&D team to see if this logic should be changed.

Do you have any feedback from R&D team? If you need I can proof that an archive->hot tier recover process is more cost efficient than the others.

Can I expect to see new features in the next release? Next August?

Hi,

Yes, I do. Here is what they said

I have asked them to see if the data path can be changed in the future builds and do some calculations to make it more cost-efficient.

Can I expect to see new features in the next release? Next August?

Sorry, but I cannot provide any ETA at this point :(

That's a delusion! Here you are https://docs.microsoft.com/en-us/azure/ ... el-tiering
"When a blob is moved to a warmer tier (archive->cool, archive->hot, or cool->hot), the operation is billed as a read from the source tier, where the read operation (per 10,000) and data retrieval (per GB) charges of the source tier apply. Early deletion charges for any blob moved out of the cool or archive tier may apply as well."

It means that the cost of moving data from archive tier to whatever warmer is the same cause it consists from the archive tier read operations.

But if the data moves to a cool tier for recover I have to pay for data retrieval, read operations and early deletion once again contrary to hot tier.

Do you see that I mean?

Yes, I believe I do.
I have already delegated changing the data path to R&D.
I do not have any ETA though.
If there is any news, I will post them here.
Thank you for your effort! We really appreciate that.
