There was a transaction in 8/2017. The backup was in 12/2017.
If I encrypted it before 12/2017, the backup should be OK.
And if I encrypted it after 12/2017,  I suppose to see a transaction history but there is just nothing.
It sounds like you're looking at the backup of a different wallet.

That would be the most desperating thing in the world, since the data recovery has a slim chance.

I had a backup of my wallet.dat a few years ago, which was encrypted for sure.
But when I try to reload it now, it shows 0 balance and no historical transactions after the whole blockchain sync, and it is weird that the option of encrypt wallet is available.
It sounds like you created this backup before you encrypted the wallet. When you encrypt it, it creates new private keys. If it was funded before you encrypted it, those keys would still be in there. But if you only funded the wallet after you encrypted it, the backup you made before you encrypted it became useless.

I am not so sure about it. But that reminds me something, thank you.

If you still have access to the drive where the original wallet was created, you can still be able to recover it even if it was deleted from that drive.
I don't know what command you use in Pywallet if it's just dump, then try other commands to retrieve these private keys.
Check the links from the quoted below

There is already a guide here how to do it check this link below.

Or try the command posted here below

The original drive was a corrupted SSD which is in a data recovery process,
and it probably won't work because it has been 6 years, I was told there were many electron dislocation on the nands.

Whether I try the bitcoin core 0.14.2 or the bitcoin 27.0, it turns out to be the same.
The wallet.dat might be corrupted because I might copy it while the bitcoin core was running.
I tried pywallet to dump the private keys but the none of them is the right one.
Also I tried btcrecover, and it said the wallet.dat is unencrypted.

Now I don't know what else to do but to ask for help, guys please help!
