Backups
Computers and phones can fail, be lost, or be damaged without warning. Backups protect your photos, documents, and important records if something goes wrong. Without a backup, lost data is often impossible to recover.
A good backup strategy includes at least one copy stored somewhere else, such as an external hard drive or a reputable cloud service. If you are not sure whether your files are being backed up, it is worth checking or asking for help. A little preparation can prevent a lot of frustration later.
