I always save my data from the notebook in the first week of the following year. And all the data and photos that have accumulated during the year so.
Is that too negligent? Should I secure more often?
You always have to ask yourself how much can / do I want to afford to lose, if this period is with you at one year then that suits.
I agree with you. I now secure more often.
If it is okay for you that is lost up to a year → no problem.
If it is NOT okay for you → secure more often.
I've sorted my old by relevance, photos secure Z.b. Me after every shoot. After editing, they disappear anyway Nas that reflects.
On the PC itself I have thus virtually no relevant data.
We can't tell you that. Statistically, of course, every day it's equally likely that one hard drive will break. So it makes sense to make a backup as soon as you put something on the hard drive of the laptop that you would be sorry to lose. As simple as that.
Easier is it with automatic backup programs. It is important to note that your hard drive has to be plugged in frequently, which would lead to complete loss of virus.
