Abstract
An exemplary method for efficiently backing up data in thin-provisioned environments may include: 1) identifying a volume to be backed up, 2) identifying a thin-provisioned storage system that contains storage space allocated to the volume, 3) obtaining information from the thin-provisioned storage system that identifies portions of the volume for which storage space has been allocated on the thin-provisioned storage system, and then 4) creating a backup of the volume by invoking read operations only for those portions of the volume for which storage space has been allocated on the thin-provisioned storage system. Various other methods, systems, and computer-readable media are also disclosed.
