# Physically Backed Up Files

__*Physical backup files*__
__*Binary backup files*__

+ A raw binary backup is faster than a logical backup because the process is a simple replica of a file or file system.
+ A physical backup is an exact representation of bits in a database file.
+ These replica save the database in exactly the same format as the TiDB database itself is stored on disk.
+ Because they are exact replica of the original files, the original backups are the same size as the original files.

A raw binary backup is faster than a logical backup because the process is a simple replica of a file or file system.

A physical backup is an exact representation of bits in a database file.

These replica save the database in exactly the same format as the TiDB database itself is stored on disk.

Because they are exact replica of the original files, the original backups are the same size as the original files.
