摘要： Described is a method, system, and computer program product for selecting a data repository within a computing environment. The data repository can exist on multiple target computing systems as a logical entity called a volume or a file system. When selecting at least one data repository, a data protection system of the computing environment analyzes the incoming data from a source computing system, in conjunction with information describing the data repositories. The data repository information, or repository characteristic information, can be stored on a repository volume table (RVT) of the data protection system. By determining a weighted selection score from the analysis of all the information available to the data protection system, the data protection system can intelligently select a data repository for storing data from the source computing system. Further, by tracking repository characteristic information on a continuous or periodic basis, the data protection system can enable emulated views of data that has been stored on the data repositories of the computing environment.

摘要： A method according to one embodiment includes receiving a request to perform a backup of data associated with an application running on multiple servers; calculating a time value based on communications with the servers, the time value calculation including at least one of a latency of at least one of the communications, and a difference between a reference time clock value and a time clock value of at least one of the servers; and communicating with I/O Handlers on the servers for initiating a coordinated backup operation on the data at about a same start time. Additional systems, methods, and computer program products are also disclosed.

摘要： Multiple target blocks on a first storage device are allocated to store a target object. The target blocks are arranged to be in a one-to-one correspondence with multiple source blocks of a source object. The target blocks are set to a non-populated state, and target blocks in the non-populated state are populated with data from corresponding source blocks. While the target blocks are being populated, if a request is received to retrieve data from one of the target blocks that is in the non-populated state, then the one of the target blocks is populated with the data from the corresponding source block and set to a populated state.

摘要： An exposed Internet Small Computer System Interface (iSCSI) target of a backup repository is defined as a source of, and a storage volume to be recovered as a target of, a mirrored pair of storage resources. The iSCSI target represents a point-in-time backup snapshot. Data from the iSCSI target is synchronized to the storage volume. The mechanisms of the illustrated embodiments leverage iSCSI with Instant Restore to reduce a Recovery Time Objective (RTO) and provide a secure transport when recovering a volume over a WAN.
