how to save the blockchain when using cli

The ganache-cli has is deprecated. Use the ganache package instead. That said, ganache is no longer maintained.

In both packages the --db option saves the blockchain state.

When I create the database using ganache/ganache-cli, why my database contains only these files: 000003.txt, CURRENT, LOCK, LOG, MANIFEST-000002.....this behavior is very recent, before this..I used to get several files.....!blockHashes!0x.., !blockLogs!0 and so on...Am I doing something wrong while creating the database...
I am using the command: ganache -h 127.0.0.1 -0 7545 -m "my mnemonic" --db path/to/db --hardfork london

That change happened in Ganache v7.0.0 back in Jan 20, 2022.

oh, thank you for the response. Is it possible to create the database in the old style? If not, is there a way to make the text file in the newer version readable? Once again I appreciate your time..

No

If not, is there a way to make the text file in the newer version readable?

It's a binary format now. Its only readable by Ganache. If you want to try to read it yourself you could use a leveldb reader like https://fastonosql.com/. But even then the data is packed tightly so it won't be meaningful without proper deserialization (which is built into Ganache).

Your best way forward would be to scrape the DB by calling Ganache's JSON-RPC methods.

Okay, thank you for the information!
