Backup & restore

Default data storage locations:

• Mac: ~/Library/Ethereum
• Linux: ~/.ethereum
• Windows: ~/AppData/Roaming/Ethereum"

Accounts are stored in the keystore subdirectory. The contents of this directories should be transportable between platforms, but is specific to the Go implementation.

To configure the location of Geth's files, the --datadir parameter can be specified. See CLI Options for more details.

Note: The mining DAG is stored at ~/.ethash (Mac/Linux) or ~/AppData/Ethash (Windows) so that it can be reused by all clients. You can store this in a different location by using a symbolic link.
