Because of the threat of ransomware, many people disconnect their backup drive when not backing up. I think that’s a bad idea.
DVDs can be a clumsy solution for backing up – especially if you want to take a full system image. It’s much better to go for an external hard drive.
Moving a file almost always leaves traces behind. So deleting any file securely is only the first step.
Certainly any hard drive can fail. Failure is a fact of life – data loss does not need to be.
Malware can certainly insert itself on external drives. The question is how high is the risk?
Quality and features in hard drives can change over time. So first, look at your needs.
If you’re backed up, this isn’t going to be a problem. Otherwise, there are only a few steps we can take to help us retrieve your data.
It’s not just power you need to worry about; connected drives can also get malware. But that doesn’t mean you can’t keep yourself safe.
It’s incredibly rare for a software crash to damage any drive connected to a computer. Other things, like a lightning strike, can do serious damage.
My fairly strong opinion is that if you’re backing up to an external drive, leave it plugged in. Otherwise you’ll be missing backups on those days you forget to plug it in.
Usually you can take the internal hard disk of an old computer and install it as an additional drive in a new one. There’s also a more flexible alternative.
