Backup to USB Drive

[bdelisa]

I'm looking to automatically backup to a USB drive when any configuration changes are made to a C9300, C9407, or C2960 catalyst switch. Is there a configuration that will accomplish this task? If there is not can I set something up to backup on a time interval?

If supported, maybe possible using archive features and/or EEM script.

You can achieve this by using the archive functionality of both IOS and IOS-XE. The most minimal config that will make a config backup to USB upon saving configuration looks like this:

archive
 path usb0:
 write-memory

You can read more about this here: https://www.cisco.com/c/en/us/td/docs/routers/ios/config/17-x/syst-mgmt/b-system-management/m_cm-config-versioning.html

BTW, although @Torbjørn also suggests the archive feature, again might not be supported.

Likely it's supported on 9k Catalysts, it's the 2960 that might not (especially if an original series model with an early IOS - it too might be fine as the archive feature has been around some time now).
