While resolving the issue, I recommend switching to the failover or replication system if available, and conducting backups according to your RPO and RTO. If this is not feasible, consider using alternative backup solutions, such as cloud storage, to create temporary backups until the hardware problem is fixed.

Rule No. 1: Do Not Panic “The more critical the operation, the higher the chance of a failure.” It’s almost a universal truth in tech. When hardware fails during a crucial moment, staying calm is non-negotiable. Here’s a few cents from me. : 1. Diagnose the issue using logs and monitoring tools 2. Activate failover systems or backups to minimize downtime and ensure data integrity 3. Containing the failure prevents it from spreading, buying time for resolution 4. Fix / Replace as fast as possible 5. Don't forget to test thoroughly before reintegrating Experience has taught me that composure and a clear, methodical approach are your best allies in times like these. It helps protect both data and you, no matter how critical the situation.

I would first investigate the root cause through Azure Monitor logs and diagnostic tools. Next, I'd restore the database from the most recent backup if available. I’d also verify the backup configuration and assess the underlying infrastructure, such as storage or virtual machine performance, to prevent future issues. In parallel, I would initiate a support request with Azure support for assistance with hardware-related issues. To avoid recurrence, I'd consider enabling automated backups, setting up geo-redundant storage, and regularly testing

if backup hardware destination is failed or damaged we can: 1. mount a external HDD to server and changing the backup destination for taking a backup 2. if external HDD not accessidable ,we can mounting a NFS storage to server and start backup process 3. if NFS storage is not accessible you can mounting Amazon S3 Cloud Storage or CEPH S3 as a disk path on linux and taking database backup to it. 4. best practice for Full backup is more than one redundancy.two or more Full backup is lovely. 5. install a new database on clean server and duplucate main db

Primarily, Identify affected components and verify backups. Notify the stack holders about the failure and action plan. Activate/switch to the disaster recovery system. Then look for the root cause, resolutions and documentation.
