Abstract
Exemplary methods for dynamically performing multiple save streams include in response to receiving a request to perform backup of an aggregate backup data, splitting the backup data into savepoints based on a splitting policy. In one embodiment, the method includes creating a first set of directors, each director responsible for backing up one of the savepoints. The method further includes allocating save streams to each of the directors, wherein each save stream is used by the corresponding director for backing up its savepoint. In one embodiment, in response to receiving an indication from a first director of the first set of directors that its savepoint has been backed up, creating a second set of directors, and allocating one or more save streams from a number of save streams freed by the first director to a second (unfinished) director from the first set of directors.
