Backup and Restore Database

Command

$ go build -o [app-name]

Run from root directory of project (incognito-chain/) $ ./[app-name] --cmd backupchain [flags]

List of flags

 --beacon: backup beacon chain
 --shardids [string params can be splited with ","] or --shardids "all"
 --chaindatadir "[string params]/block": blockchain database to be backup
 --outdatadir [string params] : directory where backup file store
 --filename [string params]: name of backup file
 --testnet: backup blockchain database is testnet or mainnet (only 2 option for now)  

Example:

• Backup:

  • Beacon: $ ./cmd/incognito --cmd backupchain --chaindatadir "../testnet/fullnode/testnet/block" --outdatadir "../testnet/" --beacon --testnet
  • Shard: $ ./cmd/incognito --cmd backupchain --chaindatadir "../testnet/fullnode/testnet/block" --outdatadir "../testnet/" --shardids 0,1,2,3 --testnet
  • All: $ ./cmd/incognito-cmd --cmd backupchain --chaindatadir "../testnet/fullnode/testnet/block" --outdatadir "../testnet/" --shardids all --beacon --testnet

• Restore:

  • Beacon: Restore only Beacon Chain

  $ ./cmd/incognito-cmd --cmd restorechain --chaindatadir /home/testnet1/fullnode/testnet/block" --filename ../testnet/export-incognito-beacon --beacon --testnet

  • Shard: Restore only Shard Chain (support multi shard at a time)

  $ ./cmd/incognito-cmd --cmd restorechain --chaindatadir "/home/testnet1/fullnode/testnet/block" --filename "../testnet/export-incognito-shard-0,../testnet/export-incognito-shard-1,../testnet/export-incognito-shard-2,../testnet/export-incognito-shard-3,../testnet/export-incognito-shard-4,../testnet/export-incognito-shard-5,../testnet/export-incognito-shard-6,../testnet/export-incognito-shard-7" --testnet

Notice

• You SHOULD Restore Beacon Chain Database BEFORE Shard Chain Database
• By default block will be stored in .../testnet/block or .../mainnet/block
