Evaluating the appropriateness of data backup types. So we do have these different backup types. We've got full backup, incremental, and differential backup. I'm just gonna jump right into them. A full backup, so this is your data, right? You're a company, you've got data, and you can choose between these three. Now, maybe you do full backup for your financial data, you do incremental backup for your customer data. You know, you can do different backup types for different types of data. But yeah, we just wanna understand kind of how these work. So for a full backup of data, this involves copying all data to the backup storage. So this is the most comprehensive, just like everything. It's a choice, right? We saw earlier, mirroring, all that. You choose one or the other. Here, there's three options. This would be, we copy, this is the most intensive, but the most comprehensive. Takes the most effort, probably the most money. But again, you're definitely covered here. You're copying all the data you have to a backup storage unit. And this is, you know, obviously gonna require more storage space and take a longer time to back up. The advantage here is that only one backup set is needed. Everything's fully backed up, you're good to go. Totally replicated, you know, like I've talked about, like if my iPhone gets destroyed, it's all in the cloud. I can just, you know, say, hey, buy a new iPhone. And then they, you know, or Android, whatever. And they put a complete replica of what was on that old phone on the new phone. It's all saved in the cloud, gotta love it. Incremental backup, this backs up only the data that's changed since the last backup. So either full or incremental.
