Employing AzCopy for Efficient Data Transfer Between Azure Storage Containers

Mar 23, 2024, 2 min read

Module 3: Assignment - 4

Tasks To Be Performed:

  1. Use the same storage accounts from previous assignment
  2. Use AzCopy utility to copy data from one storage container to another

Continuing from Assignment 3

Step 1: Install AzCopy

I install it following the instructions on the AzCopy v10 page.

Step 2: Generate SAS Tokens for Both Storage Accounts

  1. I Generate a SAS Token for the Source Storage Account:

    • I log into the Azure Portal and navigate to the first storage account (the source).

    • I go to the “Shared access signature” section and generate a SAS token.

    • I copy this SAS token for later use.
      I make in “Allowed services” only “Blob” is selected and in “Allowed resource types” I select all of them

    • I click the button Generate


      I’ll copy ”Blob service SAS URL” https://hectorstorage12345.blob.core.windows.net/?sv=2022-11-02&ss=b&srt=sco&sp=rwdlaciytfx&se=2023-12-07T11:43:22Z&st=2023-12-07T03:43:22Z&spr=https&sig=65jplHCQ0zkeBkaZrnNIDOY9pLAWSx1vkEzjYii90dU%3D

  2. I Generate a SAS Token for the Destination Storage Account:

    • I repeat the process for the second storage account (the destination).
    • I ensure to copy this SAS token as well. https://team1storageaccount54321.blob.core.windows.net/?sv=2022-11-02&ss=b&srt=sco&sp=rwdlaciytfx&se=2023-12-07T11:55:19Z&st=2023-12-07T03:55:19Z&spr=https&sig=5vLf%2Bf717PW%2Bhf%2BMwSExJ6fdDjWaZpgB%2FMs0u5pU5zw%3D

The whole command looks like this:

.\azcopy copy 'https://hectorstorage12345.blob.core.windows.net/mycontainer?sv=2022-11-02&ss=b&srt=sco&sp=rwdlaciytfx&se=2023-12-07T11:43:22Z&st=2023-12-07T03:43:22Z&spr=https&sig=65jplHCQ0zkeBkaZrnNIDOY9pLAWSx1vkEzjYii90dU%3D' 'https://team1storageaccount54321.blob.core.windows.net/mycontainer2?sv=2022-11-02&ss=b&srt=sco&sp=rwdlaciytfx&se=2023-12-07T11:55:19Z&st=2023-12-07T03:55:19Z&spr=https&sig=5vLf%2Bf717PW%2Bhf%2BMwSExJ6fdDjWaZpgB%2FMs0u5pU5zw%3D' --recursive

I opened the command prompt (CMD) where the .exe file was located and run the command.

I confirm the files from mycontainer in Assignment 2 were copied to mycontainer2


The transfer of chest.png failed because we changed the tier to 'archive' in Assignment 5: Module 2.
