Hard drives can fail without many, if any, warning signs. To prevent losing important data, frequently back up your data to a cloud service and/or another storage drive. Backing up your data is important, but only if it’s being backed up correctly. If the backups fail, you won’t be able to retrieve your documents. Test that your backups are working every so often by retrieving and opening a file. This way, if you get attacked by malware or ransomware, you will know that your files are stored safely.
