Automatic Config Archiving

A Cisco router can automatically copy its config to a TFTP server when doing a write memory or on a predetermined interval. It automatically keeps the file names of up to 15 revisions. This is very handy when combined with Configure Replace.

archive
 log config
  hidekeys
 path tftp://10.10.10.5/$h-autoarchive-$t
 write-memory

$h is automatically replaced with the hostname, and $t with the timestamp.

Example

ROUTER#show archive
The maximum archive configurations allowed is 14.
The next archive file will be named tftp://10.10.10.5/ROUTER-autoarchive-Jun-17-13:53:36.731-EDT-19
