Multi stream deduplicated backup of collaboration server data

摘要

Techniques to backup collaboration server data are disclosed. An indication to begin backup of a collaboration server dataset is received. An associated directory is walked in a prescribed order to divide the dataset into a prescribe number of approximately equal-sized subsets. A separate subset-specific thread is used to back up the subsets in parallel. In some embodiments in which the collaboration data is stored in multiple volumes, a volume-based approach is used to back up the volumes in parallel, e.g., one volume per thread. In some embodiments, transaction logs are backed up in parallel with volumes of collaboration data.

1. A method of backing up data, comprising:
receiving an indication to begin backup of a collaboration server dataset; walking an associated directory in a prescribed order to divide the dataset into a prescribe number of approximately equal-sized subsets, wherein the directory comprises a plurality of files; and using a separate subset-specific thread to back up the subsets in parallel;wherein each subset-specific backup thread is configured to provide data included in that subset to a backup-thread specific de-duplicating backup process instance configured to perform de-duplication processing with respect to the subset and a corresponding subset associated with a prior backup; and wherein the corresponding subset was determined by walking the associated directory in the prescribed order at a prior time with which the prior backup is associated.
