摘要： A system and method for object-level snapshot creation in an object-based storage system. The host device includes a first object management table (OMT) and a file system. The object-based storage system is connected to the host device and includes a controller and object-based storage devices (OSD). The controller includes a snapshot module, a second OMT. The snapshot module receives and processes OSD and other commands from the file system or a service processor, creates an original object and a mirror object in an OSD, and initiates a snapshot operation in an OSD. The first OMT may also reside at a metadata server. A snapshot operation may be a mirror operation or a copy on write operation. The first OMT and the second OMT maintain mapping information of a file identifier, a partition ID, and an object ID, and an object status and a generation number of snapshots.

摘要： Techniques to assure genuineness of data stored on a storage device are provided. The storage device includes a storage controller that conducts I/O operations and management operations. A description of management operations and corresponding timestamps are recorded to an operation log stored in a memory. The memory additionally stores an attribute for each storage volume of the storage device. Write access to each of the storage volumes is dependent on the attribute.

摘要： A method for write protection in a storage system using both the “file-level WORM function” and the “block-level WORM function”. The block-level WORM function has two modes: the first mode is to prohibit both file access and block access, and the second mode is to prohibit block access only. When a user uses the file-level WORM function to prohibit write access to a file in a volume, a file access invokes the first mode of the block-level WORM function to prohibit write access to the volume where the write prohibited file resides.
摘要翻译：一种使用“文件级WORM功能”和“块级WORM功能”的存储系统中的写保护方法。块级WORM功能有两种模式：第一种模式是禁止文件访问和块访问，第二种模式是禁止块访问。当用户使用文件级WORM功能来禁止对卷中的文件进行写入访问时，文件访问将调用块级WORM功能的第一种模式，以禁止对写入禁止文件所在的卷进行写访问。

摘要： A storage system, upon receiving a marker from a host computer, executes a generation determination process for determining a generation of a first logical volume that is used by a host computer, and writes information related to the generation determined in this generation determination process to a physical storage device and/or a memory. A backup controller determines whether or not any data or a specified file and/or folder inside the first logical volume of the immediately preceding generation has changed, and when the result of this determination is affirmative, sends a marker insert indication, which induces the issuance of a marker, to the host computer, and when the result of the determination is negative, does not send the marker insert indication to the host computer.

摘要： There is a journal area and one or more logical volumes comprising a first logical volume. The journal area is a storage area in which is stored a journal data element, which is a data element that is stored in any storage area of a plurality of storage areas configuring a logical volume, or a data element that is written to the storage area. A controller has a size receiver that receives a write unit size, which is the size of a write data element received from a computer, and a size setting unit that sets the received write unit size in a memory for one or more logical volumes. The size of a journal data element stored in a journal area based on the set write unit size is the write unit size.

摘要： One code (a compressed redundant code) is created based on a plurality of first redundant codes, each created on the basis of a plurality of data units, and this compressed redundant code is written to a nonvolatile storage area. This compressed redundant code is used to restore either a data element constituting a multiple-failure data, or a first redundant code corresponding to the multiple-failure data, which is stored in an unreadable sub-storage area of a partially failed storage device, and to restore the data element constituting the multiple-failure data which is stored in a sub-storage area of a completely failed storage device, based on the restored either data element or first redundant code, and either another data element constituting the multiple-failure data or the first redundant code corresponding to the multiple-failure data.

摘要： An information system includes a primary storage system (PSS), a host, an external storage system (ESS), and a management host. The PSS uses virtual devices to treat logical devices in the ESS as if they were logical devices in the PSS. The ESS logical devices are configured using multiple disks for providing redundancy, such as in a RAID configuration, to enable migration of data following hardware failure in the ESS. When a disk forming part of an ESS logical device fails, the management host detects the failure and judges whether the ESS logical device is used by the PSS to form a virtual device. If the ESS logical device is used to form a virtual device, then the management host issues a migration request. In response to the migration request, the PSS migrates data from the ESS logical device to a logical device in the PSS to avoid data loss.
