Within Telnet Command TFTP: Not Found

[proxybox]

I wanted to backup my mtdblock5 & 6 through Telnet on my cameras. I am running Firmware V5.2.5 _141201. I can CAT the files for backup but I cannot get it to tftp back to my server. I get the following message when typing tftp -p -l <filename> <server IP>. On my NVR, I was able to backup the files without any problems.

Oh, and to clarify on the NVR with V3.1.0_150511 the telnet is PSH (protect shell) so can't perform any tasks since it is limited?

Thanks

Yes, tftp does not exist in the running state of a 2xx2 camera.
Probably the easiest way to get your file to and from the camera is to add a 'NAS destination' in the storage menu in the web GUI.
This can be a share on a PC, or NAS box, and can be CIFS/SMB (eg Windows, needs a username/password) or NFS (usually a NAS box).
For this purpose - it does not have to be formatted, so it can be a large (ie over 250GB) volume.
The commands are as below, with the 'mount' command being used to find the actual mount point of the NAS destination that has been added.
And by the way - check out the 'cat' command for the correct way to copy the mtdblock, when you have used 'cd' to change directory to the NAS mount point.

Arigato. Worked perfectly to my ZyXEL NSA325.

I tried the windows CIFS method for kicks but it didn't work. On further searching I noticed there is an issue with CIFS and 5.2. There is a workaround by creating a separate partition for the share but I didn't want to go through that mess.
