Problems, such as memory corruption, can occur that make it necessary for you to recover your configuration
from a backed up version.
Each time that you enter a copy running-config startup-config command, a binary file is created and
Note
the ASCII file is updated. A valid binary configuration file reduces the overall boot time significantly. A
binary file cannot be uploaded, but its contents can be used to overwrite the existing startup configuration.
The write erase command clears the binary file.
