A file backup is the process of creating a duplicate copy of important files or data, which can be stored separately from the original files, to ensure that the data remains accessible in case of unexpected data loss or corruption. This backup can be restored to recover lost or corrupted data. Backing up files is an essential aspect of data security and is typically performed on a regular basis to prevent data loss due to hardware failure, viruses, accidental deletion, theft, or other disasters.
