My blockchain is 5 years behind and my friend is bringing over an up to date chain. Can I just rsync lmdb and it adds the new blocks or is it better to just paste the new chain in place of the old one? I don’t think the up to date one is pruned but if it is will that cause problems if I try to rsync it?
On Linux. Thanks.
Quickly googled about rsyncing big files. It is aparently slow, as it must checksum the whole file.
My guess would be that: If both blockchains are NOT pruned, then it should be fine but super slow If they are pruned, then since the pruning involves randomness, I guess it would be useless to rsync them. Because the history will be different.
My bet is that a normal copy would be better.
