Title: Block files, database files, and other stuff Post by: kongming208 on November 05, 2010, 10:43:54 PM Hi,
Sorry if this is a FAQ, but I didn't find the answer after a few searches. I'm currently running bitcoin on one machine, and I see in my data directory: ./addr.dat ./blk0001.dat ./blkindex.dat ./database/log.0000000017 ./__db.001 ./__db.002 ./__db.003 ./__db.004 ./__db.005 ./__db.006 ./db.log ./debug.log ./.lock ./wallet.dat If I wanted to run bitcoin on multiple machines on my LAN, and I wanted to copy the block chain so that it doesn't have to re-download, which files do I need to copy? I'm guessing ./blk0001.dat ./blkindex.dat are necessary, but what about ./__db.001 ./__db.002 ./__db.003 ./__db.004 ./__db.005 ./__db.006 And the ./database/log.0000000017, db.log, debug.log, and other files don't need to be copied, yes? Thanks for any help!

I'm guessing ./blk0001.dat ./blkindex.dat are necessary, but what about I've actually copied the blockchain before, and the two above files were all that I needed to get it to work. I'm pretty sure that the others are checkpointing files, and it's not a bad idea to let the new client checkpoint the entire blockchain after a copy anyway. I'm not certain, however, as that client was a while ago, and predates the checkpointing upon startup thing.

works fine for me so far, so i guess it's alright. i think (and please correct me if i'm worng) anything else is client-related anyway and your gonna use the copy for another client, which has/creates its own keys/hashes and DB.

You can delete them if you're sure the database is not in an inconsistent state.
