Question:
1)
We know that if you move from one storage tier cool  archive or cool  archive it will be charge.
If we use azcopy with --block-blob-tier=“archive” to copy from our NAS folder also with --recursive option directly into a container, will it be charge?

2)
Will azcopy, copy entire folder and subfolders structure with files to blob storage container?

3)
Will azcopy able to retain the NAS folders, subfolders and files ACL after it is store into blob container?

4)
Will azcopy able to retain the NAS folders, subfolders and files timestamp after it is store into blob container?

5)
Will azcopy able to remove those files from source once the file is written to target blob container?

6)
Could azcopy include files which is more than 5 years old only copy to blob container?

7) For https://azure.microsoft.com/en-us/pricing/calculator/?service=storage pricing
what are the other Read Operation for example that come under this charge which is very expensive?

There is a note as follow:
The following API calls are considered Read Operations: GetBlob, SetBlobTier (when it moves a Blob from Archive to Cool, Cool to Hot or Archive to Hot).

    @Steven Foo Firstly, apologies for the delay in responding here!

    1) We know that if you move from one storage tier cool  archive or cool  archive it will be charge.
    If we use azcopy with --block-blob-tier=“archive” to copy from our NAS folder also with --recursive option directly into a container, will it be charge? There are charges, I would recommended to contact Azure Billing team for detailed information, it's free, and it's the best choice for you.

    Azure Blob Storage pricing: https://azure.microsoft.com/en-in/pricing/details/storage/blobs/

    2)Will azcopy, copy entire folder and subfolders structure with files to blob storage container? Yes It will copy

    Yes.

    3)Will azcopy able to retain the NAS folders, subfolders, and files ACL after it is store into blob container?

    No, only to Azure Files, and only from Windows.

    4)Will azcopy able to retain the NAS folders, subfolders, and files timestamp after it is store into blob container?

    No. LMT is not able to be carried over into Blob storage as a limitation of the service. If you want LMT preservation, we recommend copying to Azure Files.

    5)Will azcopy able to remove those files from source once the file is written to target blob container?

    AzCopy does not automatically clean up the source.

    6)Could azcopy include files which is more than 5 years old only copy to blob container?

    Yes. AzCopy supports the --include-after (and --include-before) that takes in an ISO 8601 time, and takes all of the files modified after that time (or before for include-before)

    Please let us know if you have any further queries. I’m happy to assist you further.
