Latest version: OpenWrt 21.02.1
While trying to upload the sysupgrade file, I am getting below error. I have taken backup (tar.gz) just in case.
Should I ignore this warning and force upgrade? Will the backup save my ass?

does the SHA match ?
upgrading from 19 to 21 usually requires a reset of all setting, due to migration from swconfig to DSA.
Good call. Take note of /etc/config/network
changes.

You should follow the advice and "wipe config during upgrade".
So, unselect the "Keep settings"...
The backup will brick you if you restore it to the new firmware.
The old network config (/etc/config/network) is not compatible with the new DSA switch config.
Usually all other config files are compatible.
("system" may have a wrong LED config, but does not brick you.)
You might also read this for a quick & dirty approach...
Documenting here the answer that I gave to you on the other thread:
For the mvebu WRTxxxACx routers, you need changes to to /etc/config/system and /etc/config/network.
You shouldn't sysupgrade with those files in place. (and you can't restore them from old backups)
Ps.
The recommendation is to sysupgrade without settings, but a quick-and-dirty approach is to remove /etc/config/network and /etc/config/system before sysupgrade and keep the other settings. Those two will be re-generated at the…
Yes the SHA does match.
How do I migrate the configuration after upgrade? I had a very had time configuring the network last time don't want the hassle again.
What I did was use a file compare app (BeyondCompare) to see the differences between the old config and the new config...and use that as a guide.
Example...
