The article discusses some important tips to avoid SQL Server disasters and ways to improve the design.
Perfection is a mere illusion and flawlessness is an unattainable property, and the same philosophy works with computers and programming languages too. Disasters happen and the best we can do is to plan scenarios to avoid the losses. If we talk about SQL Servers, data loss is a common problem and there are many more issues. Such problems are somehow reparable and data could be recovered but it also extensively adds wastage of time and labor to your project. Bigger enterprises are less likely to take these things lightly. So the best way is to figure out ways through which the disaster situations could best be avoided and prevented. The article discusses important tips for a SQL Server Disaster Scenario.
1. Understanding the Problem
To simulate disaster recovery options, it’s advised to prepare solutions prior to disaster and to speculate what else is required. If a solution is creating more problems than it solves, then it’s not something you should stick to. Try to build the best design for the problems and understand what made you choose that design over other solutions. It’s necessary to understand the problem before pondering over the solutions. Designs should help you in taking maximum advantages from the opportunities.
2. Flaws in Design
Flaws are as natural as hailstorms, and they are really bad for your design in SQL. It’s important to understand the ways to identify the flaws and remove them from your architecture. It happens sometimes when Flaws are not visible or clear to you but they are present and affecting the clients. For Example, database going into suspect mode disabling clients to access it. It’s possible that a solution for you is a problem for them, so it’s advised to plan each and every scenario carefully and one should always be open for feedback or criticism.
3. Working on Solution
Half of the problem is solved when you successfully identify it and understand the reasons behind its cause. Start working on the solution and create reliable restore. If your solution requires alerting, make sure it doesn’t have any point of failure.
Don’t get overconfident on the code as it could create a disaster too. Failures can occur with applications or servers or solution codes that you designed. You need to practice the code, simulate it in test like environment and try to have a backup or source code of the solution. Also invest in a tool that can fix mdf database files.
4. Team Social Behavior
You will find yourself working as a team rather than an individual warrior while working with codes in SQL, and it’s important to properly coordinate and get trained with others. A team behavior helps in disaster problems and a good team is more likely to present a feasible situation then a lonesome techie. That’s why enterprises have multiple teams for Disaster recovery drills because no one likes unanticipated surprising disasters. There are System team, DBA team, developer team, etc and their work is integral and dependent on each other.
