Azcopy data transfer / residency

Question

Hello,

I want to transfer blobs between two storage accounts in the same region in Azure. If using Azcopy via the azure cloud shell, does the data transfer directly between the accounts or does it temporarily download to any intermediary? I'm trying to determine if the data will stay within the region in order to keep data residency.

Thanks,

Debbie

Hi D-6386,

AzCopy can transfer data directly between two Azure storage accounts in the same region without temporarily downloading it to an intermediary. This allows for efficient data movement directly within Azure's infrastructure.
Direct Transfer: When using AzCopy to copy blobs between two storage accounts in the same region, the data transfer occurs directly between the accounts. This means that the data does not get downloaded to any intermediary location, allowing it to remain within the region and maintain data residency.

Data Residency: Since the transfer is handled internally by Azure, the data will stay within the same region. This is beneficial for maintaining data residency requirements, as it minimizes the risk of data leaving the designated geographic area.
