The Means To Recuperate Exterior Exhausting Disk Data When It's Not Detected
Computer system reliability is improved utilizing various strategies to observe objects (e.g., processes, threads, DLLs, and so on.) executing on the system. Such strategies embrace lively techniques, in which information is frequently communicated from the thing to the monitor, and passive techniques, in which the thing does not have to repeatedly provide information to the monitor. The monitor determines when an object in the computer system has failed, and initiates acceptable recovery motion when such a failure is detected.
Other kinds of communication strategies, protocols and media are contemplated as falling within the scope of the invention. 3, as soon as the primary full snapshot to has been taken, step 300, the storage manager could implement a rule, policy, or related set of directions that require snapshots to be taken at certain time intervals. Accordingly, at every time interval the place a subsequent snapshot tn is taken, the information agent works at the aspect of a number of of the media agents to carry out and retailer snapshot and accompanying knowledge that modified since the subsequent snapshot, tn-1, loop 306. The snapshot 350 is used to associate the original cluster numbers from an info store with clusters on a storage device, which in the present embodiment is a magnetic tape. Recovery thread a hundred and seventy then checks registration database a hundred and forty four to determine whether or not the failed object had registered for a callback . If the failed object has not registered for a callback, then recovery thread a hundred and seventy identifies the suitable restoration action for the failed object .
how to recover data from external hard disk which is not detecting as recited in claim 27, wherein the object comprises an utility course of. A methodology as recited in claim eight, whereby the item includes an software thread. [newline]A methodology as recited in claim eight, whereby the thing comprises an utility process. Recovery thread 170 then checks whether it's okay to proceed with its restoration .
Update thread 166 then checks whether the difference between the present heap allocation and the initial heap allocation is larger than a threshold value . In the illustrated instance the threshold value is 200 Kbytes. Alternatively, the edge value could possibly be larger or smaller, or a process could register for a specific threshold value. Once registered, the consumer object could repeatedly ship notification messages to CPM 134 . Whether the consumer object sends notification messages to CPM 134 is dependent upon the registration type the thing provided in step 202. If toshiba external hard drive not working used a “notify” registration kind (e.g., CPM_REG_PROCESS_NOTIFY or CPM_REG_THREAD_NOTIFY in Table I above), then the shopper will send notification messages to CPM 134 at common or irregular intervals .
A system as recited in claim 60, whereby the test object comprises a test thread. An automobile laptop programmed to carry out the strategy as recited in claim 43. A system as recited in declare 33, whereby the monitor is to actively monitor the plurality of objects.
1 illustrates an exemplary pc system used in accordance with the invention. The computer 100 features a data processor 102, a system memory 104, a nonvolatile memory 106, an I/O controller 108, and a watchdog logic a hundred and ten, all coupled to a system bus 112. Data processor 102 represents any of all kinds of typical processors, using any of quite a lot of standard processor architectures or microarchitectures. According to another facet of the invention, an Application Programming Interface provides the interface between the monitor and the objects in the laptop system, allowing the objects to entry the assorted options of the monitor. According to a different facet of the invention, a watchdog logic is included within the pc system. The watchdog logic is programmed to reboot the pc if it's not accessed often.
The crucial course of monitor refreshes the watchdog logic regularly to avoid having the computer system rebooted. However, if a system problem prevents the important course of monitor from operating, then the watchdog logic reboots the pc system. The invention described beneath addresses these disadvantages, providing an improved method to monitor laptop system objects to improve system reliability. Systems and strategies are wanted, therefore, that overcome problems associated with presently recognized strategies for taking, maintaining and restoring snapshots.
