Backup & restore

Data directory

Everything gabey persists gets written inside its data directory (except for the PoW Ethash DAG, see note below). The default data directory locations are platform specific:

• Mac: ~/Library/abeychain

• Linux: ~/.abeychain

• Windows: %APPDATA%\abeychain

Accounts are stored in the keystore subdirectory. The contents of this directories should be transportable between nodes, platforms, implementations (C++, Go, Python).

To configure the location of the data directory, the --datadir parameter can be specified. See CLI Options for more details.

Upgrades

Sometimes the internal database formats need updating. This can be run with the following command (gabey should not be otherwise running):

gabey upgradedb

Cleanup

gabey's blockchain and state databases can be removed with:

gabey removedb

This is useful for deleting an old chain and sync'ing to a new one. It only affects data directories that can be re-created on synchronisation and does not touch the keystore.

Blockchain import/export

Export the blockchain in binary format with:

gabey export <filename>

Or if you want to back up portions of the chain over time, a first and last block can be specified. For example, to back up the first epoch:

gabey export <filename> 0 29999

Note that when backing up a partial chain, the file will be appended rather than truncated.

Import binary-format blockchain exports with:

gabey import <filename>
