XR configuration Auto Backup

[Eddie Chami]

Ever wondered how to backup the running configuration in XR each time a commit is made? Many operators use offline scripts that do this periodically, that surely works well. Another simpler method is to have the system upload/backup its config each time the configuration is modified, this ensures the configuration is always up to date. Just add this command to the config:

This is an example with the server reachable inside a VRF(MGMT) on the router.

#configuration commit auto-save filename tftp://10.1.1.100;MGMT/XR_Nodes/asr9922_london.cfg

interface Loopback1

description in-band-mgmt

vrf MGMT

ipv4 address 10.1.1.1 255.255.255.0

This is an example with the FTP server reachable in the default routing table. RCP can be used. 

#configuration commit auto-save filename ftp://user:password@10.1.1.100/XR_Nodes/asr9922_london.cfg

How to change file name to include date & time so that backup files are not overwritten.

[Eddie Chami]

Nishant,

The team just made a change in XR whereby we append the file with date/time stamps, so XR will take care of this.

[Eddie Chami]

Yes, this is going in 6.1.2 which is ~Oct.

That should support from 6.2.1, follow by CSCuu24747.

Hi Chami

When i configured comand .

#configuration commit auto-save filename tftp://10.1.1.100;MGMT/XR_Nodes/asr9922_london.cfg

Every time when i commit command. System confirm:

This could be a few minutes if your config is large. Confirm? [y/n][confirm]

I think It's quite inconvenient.
