    Abstract: A storage system, such as a file server, creates persistent consistency point images (PCPI) or “snapshots” that are point-in-time representations of the storage system. The storage system uses persistent consistency point images to backup or mirror data. Using data already found in the data block maps associated with these PCPI, the rate of change of data between persistent consistency point images can be determined.

    Abstract: A file system receives a request to set a capacity guarantee for a virtual volume associated with a logical aggregation of physical storage. In response, the file system sets the capacity guarantee to indicate that the logical aggregation of physical storage is to provide a specified amount of space to the virtual volume. The amount of space provided to the virtual volume may be based, at least in part, on a guarantee type. The guarantee type may include, for example, volume, file, none, or partial.

    Abstract: A system and method are provided to manage storage space. The method comprises detecting a free storage space threshold condition for a storage volume and automatically applying a space management technique to achieve a free storage space threshold condition. Space management techniques comprise deleting selected backup data (e.g., persistent consistency point images) and automatically increasing the size of the storage volume.
