Backup – Your copies for the worst case scenario
Regular backups are part of the basic repertoire of IT security-conscious users. This protects you against data loss, for example, in the event of a defective or lost device or an ransomware attack. In the event of a ransomware attack that encrypts your files, a backup is often the only way to get back your valuable data.
Therefore, you should make regular backups, to a medium that is not permanently connected to your PC.
One possibility is an external hard drive, which – if not backed up – you will keep in a safe place. Another possibility for TU members is the backup service offered by the HRZ (see ). homepage of the HRZ
This video from the BSI briefly summarizes what you need to keep in mind when backing up.
