  • Method, computer program product, and system for providing a multi-tiered snapshot of virtual disks
    Patent number: 7734954
    Abstract: An object in a tier of a multi-tier virtual storage system is saved while the storage system is active. The object to be saved in an upper-level tier in the multi-tier storage system is identified. Servers associated with lower-level tiers below the tier containing the object to be saved to obtain the latest data stored in the respective associated tiers, use temporary storage to store the obtained data and handle any modifications to the obtained data, and cause applications running in the respective tiers to quiesce. Once a copy of the identified object is made, the servers associated with the lower-level tiers are instructed to obtain the data from the temporary storage and resume quiesced applications running in the respective tiers.
