is there any way to backup bitcoin node or blockchain data?
Blockchain data and almost everything important resides on your external hdd. If you already have lightning channels, I would download that backup too (channel.backup).

@Raj, Hi. Seems that I encounter the same issue right now. Have you found a solution for it?
Thanks!
Any solutions to this issue, I think I have a similar problem Reflashed my micro SD card yesterday. Core is 100% synced, still waiting for lightning wallet and umbrel wallet to sync.

I have done two transactions to my wallet. the first one showed up in my wallet, then I did a second one, could never see it in my wallet, even though it looked correct in the blockchain explorer.
I decided to reinstall my Umbrel server and restore it. I can now see my second transaction but not the first one…
Edit:
I ran the list chain transactions ~/umbrel/bin/lncli listchaintxns to see if I could see my transactions. And only the last transaction is listed.
I imported my wallet into blue wallet to see if I could see my BTC or at least get the xpub of the wallet.
And turns out that all my BTC is visible in the blue wallet.
