Do you use CDs or DVDs for storage?
If you have or use CDs or DVDs for the storage of important photos/documents etc., be aware that due to the composition of the surface, their expected life is 2 - 5 years. Therefore, always rerecord them if you prefer to use CDs or DVDs, before this happens. As well as storing files on your PC, you can also backup files to the 'Cloud', i.e. Microsoft OneDrive or Google Drive. You can also back up to USB key drives* or external hard drives*. Never have important files in one place only. If something is really important, then have copies at another location (in case of fire/theft) for instant access, without having to download them from the cloud, which can take a long time.
*Both of these devices can fail.
