Abstract: 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.

Abstract: Techniques to backup collaboration server data are disclosed. A plurality of separate threads are used to back up a prescribed number of subsets of a dataset. Each subset of the prescribed number of subsets was determined by walking an associated directory in the prescribed order at a prior time with which a prior backup is associated. A separate thread is spawned to backup transaction logs associated with the dataset. A first pass backup of the transaction logs is performed in parallel with the backup of the prescribed number of subsets.
