What type of backup consists of copying everything on a hard drive each time a backup is performed?

The type of backup that involves copying everything on a hard drive each time a backup is performed is known as a full backup. This method creates a complete and exact copy of all the data contained on the specified storage device. Full backups are crucial because they ensure that all files, settings, and system states are preserved in one comprehensive backup file or set of files.

In contrast to other backup types, such as incremental backups, which only copy data that has changed since the last backup, a full backup captures the entire system at that point in time. This makes it easier to restore the system completely, as you have all the necessary files in one place. While full backups can require considerable storage space and time to complete, they provide a straightforward and thorough backup solution, making recovery straightforward and efficient.
