Provided are techniques for determining whether content of an object has changed. Under control of a backup system, opaque object attributes and a data identifier are received, wherein the data identifier is generated based on one or more relevant object attributes of the opaque object attributes that indicate whether at least one of the content of the object and one or more of the relevant object attributes has changed. The received data identifier is compared with a previously stored data identifier. In response to determining that the received data identifier and the previously stored data identifier do not match, it is determined that the content of the object has changed.

Techniques are provided for processing an Input/Output (I/O) request. At least one data block is allocated for use in completing the I/O request. A current operations record is stored for the I/O request. It is determined whether the I/O request has been completed within a specified period of time. In response to determining that the I/O request has not been completed within the specified period of time, the allocated at least one data block is fenced.

File system objects of unknown type are backed up and restored. A list of file system objects is received from a file system. The file system objects are to be backed up. For each file system object that has a file type that is unknown, the following is performed. First, the file system is queried to obtain information regarding the file system object that is sufficient for the file system to later recreate the file system object if necessary. Second, the file system object and the information regarding the file system object are stored. Examples of file system object types of the file system that may be unknown to an application running on a Microsoft Windows® operating system include symbolic links, named pipes, and special device files.

A method, system, and article for management of email communication content across a computer system network. An archive of email communications is retained on storage media in communication with the network. In addition, email communication is retained on storage media in communication with a client machine in the network. To mitigate duplication of email communications, duplicate communications are replaced with a hyperlink to the archive communication. This replacement supports removal of the duplicate communication from the storage media in communication with the client machine.

In a method for selecting a parking lot exit, a computer receives geographic coordinates of a first parking exit of a parking facility. The computer receives geographic coordinates of a second parking exit of the parking facility. The computer determines a first route from the first parking exit to a destination, using the geographic coordinates of the first parking exit. The computer determines a second route from the second parking exit to the destination, using the geographic coordinates of the second parking exit. The computer selects one of the first parking exit and the second parking exit based on the first route and the second route.

Systems, methods and computer program products are disclosed herein for assigning visual characteristics to records of a data structure and displaying those records. In response to an attribute being selected, records of the data structure may be sorted by values of the selected attribute of the records. A first set of records having values of the selected attribute that correspond to a first value may be identified. A second set of records having values of the selected attribute that correspond to a second value also may be identified. A first visual characteristic may automatically be assigned to each record of the first set of records and a second visual characteristic, that is different from the first visual characteristic, may be automatically assigned to each record of the second set of records.
摘要:
A technique for avoiding a ping-pong effect on active-passive paths in a storage system managing one or more logical storage units (LUNs) on behalf of one or more host systems. A first path to the LUNs is designated as an active path and a second path to the LUNs is designated as a passive path. The first path is also designated as a preferred path to the LUNs. In response to a path failure in which a host system cannot access the LUNs on the first path, a failover operation is implemented wherein the second path is designated as the active path and the first path is designated as the passive path. The designation of the first path as the preferred path to the LUNs is not changed. Subsequent failback operations are conditionally inhibited so that only the failover host that initiated the failover is permitted to initiate a failback.
