Testing Your Backups – Disaster Recovery Requires Verification

There are a few times I have been taught the value of testing your backups. That is why even disaster recovery needs to be validated. The first story I share is probably a worst-case scenario. However, it can happen, so we need to be aware of failure points. We must validate our backups regularly to ensure the process we are counting on is there when we need it. Testing Your Backups Before They Are Needed There are many ways to test backups and our disaster recovery plan. We can do the extreme version, cut power to the required systems, and attempt to replace them via the procedure. However, that may not be needed. We may be able to do partial... Read more

Sweeping Consequences – Avoid All In Until You Are Sure

There is an old joke about sweeping consequences in IT related to wildcard commands like “rm -rf *.” However, there are ways to avoid getting bit by them. For example, we can do test runs and subset queries before doing the real thing. While it is undoubtedly faster to rip off one of those commands, it is also dangerous. This episode looks into some tricks of the trade I learned after countless times of being tripped up by this concept. Sometimes Easy Creates Sweeping Consequences A database is the best tool for examples of doing something quick and dirty that ends up costly. We can see this even with resource usage before more significant effects like data loss or corruption.... Read more

A Car Sale – Acceptable Loss And Walking Away

We continue the series about errors and recovering with an excellent example of acceptable loss and when to walk away. We see these appear in negotiations regularly. They are shown in movies, television shows, and in real life. We walk away regularly without even realizing it. So yes, when you decide not to purchase an item or enter a store because of products or pricing, you are walking away from the negotiation. Determine Acceptable Loss Up Front The key to being able to walk away from any negotiation is to determine your breaking point beforehand. This preparation allows us to detach emotion from the negotiation and have a way to hold ourselves accountable. It can prompt the internal conversation of... Read more

Key Performance Indicators – Measure Your Spending

This episode looks at a marketing campaign and my lack of paying based on key performance indicators or KPIs. This was a slightly costly mistake and, thus, one that sticks in my memory. The mistakes that cause us some level of pain are also the easiest to remember. However, that is not the only lesson to learn from this past mistake. KPI – Key Performance Indicators Any form of sales or marketing campaign can be a black box when we do not set KPI values. There must be a way to measure success (or failure), and our metrics are the key performance indicators. For example, most advertising campaigns focus on clicks or leads for a measure of potential additional sales. ... Read more

Ask Questions To Show Knowledge – A Bad Interview

In this episode, our trip down memory lane stops at my first professional interview and when I learned to ask questions. It is thought by many that those that know never ask. However, that is far from the truth. There are always details to be learned. Likewise, good questions can impress others in an interview or other assessment situation. Smart people still ask questions; they ask insightful ones. You Provide Insight When You Ask Questions This story is about an interview, and that is the number one situation in our lives where we want to provide a lot of information in a short period. A good interview goes deep quickly and gives the audience a chance to understand us to... Read more
