A Cisco router can automatically copy its config to a TFTP server when doing a write memory or on a predetermined interval. It 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 $t with the timestamp.
It automatically keeps the file names of up to 15 revisions.
Example
ROUTER#show archive The maximum archive configurations allowed is 14. The next archive file will be named tftp://10.10.10.5/ROUTER-autoarchive-Jun-17-13:53:36.731-EDT-19 Archive # Name 1 tftp://10.10.10.5/ROUTER-autoarchive-May-13-22:54:50.924-EDT-9 2 tftp://10.10.10.5/ROUTER-autoarchive-May-14-00:08:13.761-EDT-10 3 tftp://10.10.10.5/ROUTER-autoarchive-May-21-09:11:36.401-EDT-11 4 tftp://10.10.10.5/ROUTER-autoarchive-May-27-09:31:10.138-EDT-12 5 tftp://10.10.10.5/ROUTER-autoarchive-May-29-10:11:35.187-EDT-13 6 tftp://10.10.10.5/ROUTER-autoarchive-Jun--6-22:59:05.218-EDT-14 7 tftp://10.10.10.5/ROUTER-autoarchive-Jun--7-22:25:48.223-EDT-15 8 tftp://10.10.10.5/ROUTER-autoarchive-Jun--7-22:40:00.973-EDT-16 9 tftp://10.10.10.5/ROUTER-autoarchive-Jun--9-15:08:47.435-EDT-17 10 tftp://10.10.10.5/ROUTER-autoarchive-Jun-16-22:06:53.605-EDT-18 <- Most Recent
At any time, you can archive your running config without saving it to the startup config:
archive config
Comparing Revisions
The device can also do a diff (compare) of two files.
show archive config differences <file1> <file2>
Example
ROUTER#$show archive config differences tftp://10.10.10.5/ROUTER-autoarchive-Jun--9-15:08:47.435-EDT-17 system:running-config Loading ROUTER-autoarchive-Jun--9-15:08:47.435-EDT-17 from 10.10.10.5 (via FastEthernet1): !
