CD-RWs are perfect for this use because you can add and delete data from them again and again. This is the most basic type of CD.

When you buy a CD-R, you typically buy it empty and write your data on it.
You can write data to this type of CD once. When you buy a CD-RW, it typically comes empty. You add your data to it.
However, unlike the two other types of CDs, you can also delete data from it and write new data onto it as many times as you like. As long as you take care of the disc, its integrity will not be compromised by writing, deleting and rewriting on it. The versatile CD-RW can be helpful in a small business setting as a way to store data offline. While the cloud is used extensively and wisely by businesses and individuals to store data, a second form of backup is strongly recommended. Storing information and important documents only on individual computers or your local network is a setup for disaster.
Everything is susceptible to loss should anything happen to your computers or your network.
