Scheduled backup to TFTP server

[disturbedone]

I'd like to schedule a backup of my Catalyst 4507 router to a TFTP server every month. I have managed to use the kron feature to do this but I'd like to add variables to the filename it stores it as.

The current config is:

kron occurrence SaveConfigSchedule at 10:21 Dec 17 recurring
 policy-list SaveConfig
!
kron occurrence Backup at 10:36 Dec 17 recurring
 policy-list Backup
!
kron policy-list SaveConfig
 cli write
!
kron policy-list Backup
 cli show run | redirect tftp://10.11.0.23/test3.cfg

Ignore the date/time as this is just for testing at the moment. It saves the running-config to startup-config using the write command and a few minutes later it copies the config to a TFTP server. This works successfully but always stores the file as test3.cfg.

Is it possible to use a variable and have the file called eg {hostname}-{date}-{time}.cfg so it doesn't overwrite the file and it is clearly identifiable when the backup is from?

I have seen the archive command used here and here but it stores the timestamp at the end of the filename and I end up with eg hostnameDec-17-11-51-32.811-0 (when the path is tftp://10.11.0.23/$h) or hostname.cfgDec-17-11-51-32.811-0 (when the path is tftp://10.11.0.23/$h.cfg).

Is there a nice way to do this and get the hostname/date/time with a proper file extension eg .cfg?

If you have linux, you can use RANCID to automate backups (and it will store them in subversion or cvs).
