How to keep remote file dates/times in sync with source?

[Bungle]

I have USB storage attached to my router (TP-Link Archer VR2800) to which I am trying backup files via ftp, but it keeps giving error.. "Server does not support the MFMT command".

The problem with ftp is it only copies files with the current file time/date and doesn't support MFMT. So FFS is unable to use the MFMT command to modify the time/date to match the source.

If it didn't matter about the date stamps then I could just compare by file size only but I need the file dates/times to match exactly.

I thought of mapping the remote drive as a network shared SMB instead of using ftp but my router only supports SMB1 and win10 only allows SMB2 because of security issues. I think there may be a way to enable SMB1 but even if I do get it working I'm not sure if that would allow FFS to use MFMT command.

So question is:- Does anyone know of a way to use FFS and keep the remote file dates/times in sync with the source?

Please do not suggest trying another router, this is not an option.

Something with robocopy is probably the best bet

From reading the forum I assume nobody has found a way around this limitation of FTP/SFTP protocol. As I require file dates/times to match exactly this means using my router attached USB drive is a no go.

Related question:
I’ve been given a Netgear ReadyNAS NVX RNDX4410 NAS server. I know nothing about these devices. Does anyone know if this device is capable of preserving file date/time when backing up with FFS or is it just a more complicated version of my usb drive in the router?

Thanks, I’ll look into that.
