Backup the configuration of a Cisco Layer 3 switch Or any Cisco Network Configuration

Hello to all experts,
I have a rather complex network which contains all Cisco Switches (3560 POE) , Cisco Routers and Cisco Firewalls (ASA 5512X). My Routers are handled by a 3rd party company but the Firewalls and Switches I maintain except 3 Cisco 881 Routers. The configurations are very complex and have mostly been done by Cisco Engineers. What I require is a way to perform a complete backup of the configurations on my Switches, Firewalls, and 3 Cisco 881 routers. I have made a backup before on the switches and on my old ASA 5505 Firewalls, but now I have upgraded the Firewalls to the ASA 5512 X, as well as I have a layer 3 switch as my default routers in 3 locations. What I would like to know is there a best practice to follow to backup all these configurations to a TFTP Server. Like I had said I had made backups in the past using the following commands:
copy running-config tftp
And then making sure I have a TFTP Server running (I use Solar Winds TFTP Server). So the configurations do copy but I have noticed that I do not get a complete Configuration when I copy the running Configuration. I do go most of it but and I cannot really tell you exactly what I do not get. I worked with a Cisco Engineer a few months ago that helped me with backing up a Cisco 3560 Layer 3 switch due to the fact that I needed to upgrade to a new Layer 3 switch that had 48 Ethernet channels vs. the 24 channel on that I had. He had me make a backup of the 24 channel switch in the same way I ran above, but afterwards there was all kinds of commands that needed to be run and tweaking of the configuration in order for the new one to be configured correctly. So does anyone have any ideas on how I make a complete backup configuration of these types of devices so just in case I lose a switch or a firewall or a router and have to get a replacement one I can easily restore the configuration to the replacement?
Thank you,

In our network, which is also completely Cisco, we use CatTools to back up all configurations nightly. This gives us the added benefit of running a compare of the current config to the previous config and also we have everything set to log who made the changes to the configs based on who logs in. This part isn't foolproof because if multiple people log in and make changes it only logs the last person but dues get all the changes.

 We have mostly layer 2 switches, about 3/4 are POE, with one 4507 layer 3 with 3 switch modules in it. We have not experienced any issues with not getting a complete backup.

OK So does anyone have any ideas where I do not have to spend $750.00 to create a backup?

There are several methods that can be used.  See:  http://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/ios-software-releases-122-mainline/46741-backup-config.html

I used to use the Terminal Emulation method before we purchased CatTools.  I have never tried the Kron method. I never experienced the issues you describe with either the tftp or ftp methods when I did use them though.
