geth export file name

Question

I have a private etherum node setup in local machine and I want to try geth export command. For this I need to specify the .rlp file . Can anybody help me to locate the .rlp file.

Answer 1

You don't need to to specify name of an existing file. You need to specify name of the file to export blockchain data into. Geth will create this file and fill it with information.

So you do:

geth export my-file.rlp

to dump blockchain data into file my-file.rlp, and then, probably on another machine, you do:

geth import my-file.rlp

to load blockchain data from file created by geth export command on first machine

Answer 2

in addition to also @Mikhail Vladimirov, there are official wiki here: https://github.com/ethereum/go-ethereum/wiki/Backup-&-restore

other options to export until specific block numbers(ex: from zero to 29999 to my-file.rlp file),

You can do :

geth export my-file.rlp 0 29999
