从 Hyperledger Fabric v2.0 恢复备份
Restore Back up From Hyperledger Fabric v2.0

https://www.devprovider.com/how-to-restore-hyperledger-fabric-from-backup/
我按照这 2 个教程来备份和恢复我的区块链，我做了所有相同的事情，除了：
备份：
1:
cp –r crypto-config/ backup/
我自己的组织文件夹：
test-network/organizations$ ls
ccp-generate.sh ccp-template.json ccp-template.yaml cryptogen fabric-ca ordererOrganizations peerOrganizations
然后：
./network down for restore on next steps
2:
我需要 sudo cp 而不是 cp，因为否则无法复制 .key 文件，之后，我 运行 chown 也将我的配置文件设置为所有者
恢复备份：
1:
cd backup/ && cp -r * ../ && cd ../
通过 sudo cp 更改它...并分 2 个步骤进行（与创建备份相同）
2:
./byfn.sh up
我没有那个脚本，但是教程说：
Previously the network was started using ./byfn.sh up command. Use the same command
$ ./byfn.sh up
or if the network was started using a different script, use it. You’ll notice the peers will automatically join the channel created previously before the network is brought down. The ledger data will be restored and the number of blocks will resume from where the previous network left off.
所以我用
./network.sh up createChannel -c mychannel -ca for create my channel
像往常一样，它让我出错：
输出：
Creating channel 'mychannel'.
If network is not up, starting nodes with CLI timeout of '5' tries and CLI delay of '3' seconds and using database 'leveldb

根据你的描述，在tourial中，fabric版本是v1.4.X，而你现在使用的fabric是v2.x.x，所以在v1.4.x中测试脚本是 byfn.sh 而在 v2.x.x 中测试脚本是 network.sh，这两个脚本是不同的。
如果你想备份一个结构网络并恢复，你只需要备份加密配置（v2.x.x中的组织），从docker容器的/var/hyperledger/fabric获取的分类账数据,并启动你的orderer和peer容器，你不需要创建通道或加入通道，你可以查询和调用chaincode。
