System files may reside in four locations:
■ The system space
■ The user space
■ A network host
■ The standby SRP module
The system space contains files for system operation. For example, the current
software configuration is stored in the system space.
The user space is reserved for FTP server operations and has the typical directory
structure of a secure FTP server. The root or top level directory is a read-only directory
that contains two subdirectories:
■ /incoming—Read-write directory to and from which an FTP client can send and
retrieve files.
■ /outgoing—Read-only directory from which an FTP client can retrieve files.
Users can transfer files through FTP to the user space from a network host and vice
versa. However, users cannot access the system space through FTP. To install a file
from the user space to the system space, use the copy command. For detailed
information about transferring files between locations, see “Transferring Files” on
page 300.
To conserve NVS and minimize the installation time, files are not stored in both the
system space and the user space. When you issue the copy command to install a
file from user space to system space, the E Series router establishes a link to the file,
but does not make a physical copy.
