Abstract
A computer-implemented method for performing live backups may include identifying a request to perform a live backup on a volume of data. The computer-implemented method may also include creating a snapshot of the volume. The computer-implemented method may further include identifying each attempt to write to the volume during the live backup. The computer-implemented method may additionally include, for each write attempt, identifying a block of data that the write attempt will overwrite and copying the block of data to a backup queue before allowing the write attempt. Various other methods, systems, and computer-readable media are also disclosed.
