Automatic Backup of Switch Configurations.

Kinshuk_Tech · February 2022

Hi there,
Recently we are undergoing implementation of several ZyXEL switches in an enterprise customer. Switches include XGS4600, XS3800, MGS3750, XS1930, XGS2210, XGS2210, GS1920, GS1350 in good quantities. I know, there is an option to take backup individually, by going into each switch UI. But it takes only config log. Not running configuration.

But, now customer wants to setup an automatic backup for running config of all switches, at specific frequency ie. month, date, time etc.
How can this be achieved? I have gone through almost all places, but couldn't find anything around this.
Any help, will be highly appreciated.

Hi @Kinshuk_Tech,

Welcome to Zyxel Community!

I know, there is an option to take backup individually, by going into each switch UI. But it takes only config log. Not running configuration.

First, may we know which switch model cannot back up running config but config log only? Zyxel switch should be able to back up either running configuration or startup configuration(Config 1 & Config 2) individually via switch GUI.

Sorry that Zyxel switch does not offer feature of auto backup config. If you would like to achieve it, you may use other 3rd party tool on customer's network.

So here the questions, does all these models
(1)support to use SNMP to backup configuration to external TFTP server ?
(2)support use CLI to backup to external TFTP server ?
(3)support use CLI "show running-config" ?

You are right. @Zyxel_Adam. I didn't see it thoroughly.
Yes, almost all ZyXEL devices have the option to select running configuration and startup configuration as well, albeit, it needs to be done, one-by-one and cannot be taken simultaneously.

Thank you @lan31
Appreciate your help in this. We are also thinking on these lines, but not yet started working on it.
Anyways, thank you once again.
