Archiving SQL database backups using Azure blob storage

It is a good practice to keep multiple copies of our most precious data. By using on-premises SQL Server databases for AX 2012 or Dynamics 365 Finance and Operations, archiving SQL database backups to offsite-locations are a must. I have built automation for archiving SQL database backups using Azure Blob Storage.

Overview of the processes

Maintenance regime

Our maintenance regime looks like the following:

1x Weekly Full backup
6x Daily Differential backup
15 minute Transactional log backups

They are captured locally on the primary SQL instance, to keep the timestamps for last successful backups in our AlwaysOn cluster. Then we move the files to a shared network storage, which is visible to both High Availability sites, in case there is an outage and we need to a fail over and restore data.

In case of a natural disaster due to the close geographical proximity of the sites we needed an additional layer of safety.

Archiving offsite

Every night we are running a PowerShell script that uses the AzCopy utility. It is uploading our backup files on a Microsoft Azure cloud storage account.

You are paying for the network usage (IO) and the size occupied on the disks, so it is a good idea to have some sort of housekeeping. Our solution was to use an Azure RunBook to determine what to keep and what to delete. The current setup is to have 1 full backup file for a year available every quarter (4x 400 GB), and keep all full / differential / transactional files for the last month (4x 400 GB + 26x 10 GB).

This puts the total size occupied around 4 TB, and costs about 35 GBP a month using a cold storage. This price could go up if you also want to utilize a hot tier storage for the latest backup set. That is useful if you want to come back from the cloud on a short notice.

Add call stack to InfoLog messages

The main communication channel for our ERP users in case we want to tell them something is via the InfoLog messages within Microsoft Dynamics AX. In case we get an error or a warning, the technical staff does not receive the details required to troubleshoot the issue much easier. In this post I would like to show you how to send the X++ or .Net CIL call stack to InfoLog messages.
Microsoft already has an article on this for AX 2009, but that was before the AX 2012 IL code execution for server-side code, so it needs slight adjustments.

My changes got the following improvements:

Can handle X++ and CIL execution.
Users only see the call stack when clicking the message line due to filling it with whitespace.
Specific users could be excluded from receiving the call stack, we are doing this for our service accounts such as the batch execution account. We are also excluding our eCommerce portal customers from seeing a call stack, which are the Claims-based users.
Current database server/name and user account is included in the message, in case we are storing the errors in the Event log and would like to know who had the problem.

Here is the example output:
