  • Hi,

    Thank you for posting here! We are happy to assist you.

    The minimum possible value for option /SplitSize is 32MB. If the specified destination is Blob storage, AzCopy will split the data file once its sizes reaches the blob size limitation (200GB), regardless of whether option /SplitSize has been specified by the user.

    If the table data is exported to a blob, and the exported file size reaches the 200 GB limit for blob size, then AzCopy will split the exported file, even if this option is not specified.

  • Block blobs are limited to 200GB. A VHD file is a page blob, which can be up to 1 TB. You should be able to copy that to another account using AzCopy ( or use CopyBlob in PowerShell.

    Have you tried either of these methods?
