Cisco - How to backup Cisco switches using TFTP

There are several ways on how backup Cisco switches (or other vendors name) can be done.

One of them is downloading TFTP client server

Launching it and deciding where saving configuration files.

Be aware taking note about client IP.

Later you need to connect to switches using any SSH clients (I warmly suggest using these clients:

  1. Solar-PuTTY Connect to any server or device in your network with Solar-PuTTY for Windows. This is an interesting Putty or PuttyCM alternative.

and execute below commands on switches:

Router#copy tftp: running-config

Address or name of remote host []?

Source filename []? backup_cfg_for_my_router

Destination filename [running-config]?

Accessing tftp://

Loading backup_cfg_for_router from (via FastEthernet0/0): !

[OK - 1030 bytes]

1030 bytes copied in 9.612 secs (107 bytes/sec)



  • must be substituted by your client ip address where tftp is under execution.

  • backup_cfg_for_my_router is backup file name that will be created on client where tftp is under execution.
You can configure automatic backups, you simple need to read all article below indicated.

Veeam 11 - CDP (RPO= 0) and immutable storage backup against ransomware

 Veeam 11 released new features, here they are two that, imo, are very interesting:

  1. Continuous Data Protection (CDP) with RPO equal to zero:

    Using vSphere APIs for IO Filtering (VAIO)

  2. Immutable primary backup storage with a hardware-agnostic touch: enables you to store your short-term retention backups locally onsite for fast recovery with the protection of immutability. In addition, you can now tier those backups into an immutable object storage offering offsite, giving you additional protection against unforeseen malicious activity or accidental deletion. (protecting you against ransomware and malicious acts)

    The new hardened repositories are compliant with the SEC 17a-4(f), FINRA 4511(c), and CFTC 1.31(c)-(d) regulations. They can effectively prevent ransomware encryption or accidental/malicious deletions. The great thing about the new feature is it is based on "bring your own" Linux, so there is no vendor hardware lock-in.

    The new hardened Linux-based repositories with immutable backups will take ransomware protection to the next level for on-premises backup storage. Businesses can ensure business-critical backups are protected for the time specified for the immutable backup repository.
