LevelDOWNHyper is a fork of LevelDOWN and uses HyperLevelDB as backend. It extends the LevelDOWN api with functionality to do live backups. This README only documents the liveBackup() method. For a complete reference we refer to LevelDOWN.

LevelDOWN can be considered an upstream repository to LevelDOWNHyper and any common logic and bug fixes will be merged from upstream into this repository.

liveBackup(name, callback)

liveBackup() is an instance method on an existing database object, used to make a live backup of the current state of the database.

The name parameter is a String. A successful live backup will result in a backup folder named backup-:name inside the location folder of the current database.

The callback function will be called with no arguments when a live backup was successful, or with a single error argument if the backup operation failed for any reason.


LevelDOWNHyper is an OPEN Open Source Project. This means that:

Individuals making significant and valuable contributions are given commit-access to the project to contribute as they see fit. This project is more like an open wiki than a standard guarded open source project.
