Managing Configuration Files
It might take a minute or two to save the configuration. After the configuration has been saved, the
following output appears:
[OK]
Router#
This task saves the configuration to NVRAM.
Managing Configuration Files
On the Cisco CSR 1000V, the startup configuration file is stored in the NVRAM partition. As a matter
of routine maintenance on any Cisco router, users should backup the startup configuration file by
copying the startup configuration file from NVRAM onto one of the router’s other file systems and,
additionally, onto a network server. Backing up the startup configuration file provides an easy method
of recovering the startup configuration file in the event the startup configuration file in NVRAM
becomes unusable for any reason.
The copy command can be used to backup startup configuration files. The following examples show the
startup configuration file in NVRAM being backed up:
Example 1: Copying a Startup Configuration File to Bootflash
Router# dir bootflash:
Directory of bootflash:/
11 drwx 16384 Jan 24 2012 04:53:55 -05:00 lost+found
12 -rw- 289243620 Jan 24 2012 04:54:55 -05:00
