This article details how to copy files from one location to another in a Routing Engine.

Copying a file from one directory to another

In order to move files from one directory to another on a local router, use the following command:

user@host> file copy <source> <destination>

Example: user@host> file copy /var/log/file1.txt /var/tmp/file1.txt

In this example, the file file1 is copied from the /var/log directory to /var/tmp

 

Copying a file from one Routing Engine to another:

On Dual Routing Engine routers, sometimes there is a need to copy files from the primary RE to the Backup RE, and vice versa.

To copy a file in such a situation, use the following command:

user@host> file copy <source> <destination>

Example From RE0 to RE1: 
user@host>file copy /var/tmp/jinstall-11.2R1.7-domestic-signed.tgz re1:/var/tmp/jinstall-11.2R1.7-domestic-signed.tgz

In this example, when run in the primary RE, the Junos image on the primary RE is copied from the /var/tmp/ directory to the /var/tmp/ directory on the Backup RE.

For more details on how to copy configuration files from the primary RE to the Backup RE, refer to Copying a Configuration File from One Routing Engine to the Other.

 

Copying files from a local router to a remote host:

To copy files from the local router to a remote host, FTP or Secure Copy Protocol (SCP) can be used:

root@host> file copy filename ftp://hostname/filename

Example: root@host> file copy /var/log/messages ftp://ftp.juniper.net/2012-0101-0001/messages

In this example, log messages from the local router are copied to the juniper FTP server as anonymous under the directory of 2012-0101-0001.
