摘要:
A restoration technique includes storing a collection of blocks having (i) a first baseline of blocks defining a file at a first time within a predefined window, (ii) older blocks, and (iii) newer blocks. The technique further includes providing a direction signal to restore the file at a particular time from the collection of blocks. The direction signal has an older direction value when the particular time is older than the first time and (ii) a newer direction value when the particular time is newer than the first time. The technique further includes forming, from the collection of blocks, a second baseline of blocks from the first baseline of blocks and additional blocks. The additional blocks are either (i) the older blocks or (ii) the newer blocks depending on the direction value. The second baseline defines the file at the particular time.

An improved technique involves providing a set of reserved address assignments to a DHCP server, each reserved address assignment including a unique MAC address and a reserved IP address which are associated with each other via that reserved address assignment. The technique further involves providing a base virtual machine image and a set of unique MAC addresses, and generating multiple virtual machines from the base virtual machine image and the set of unique MAC addresses. Each virtual machine (i) provides a particular unique MAC address of the set of unique MAC addresses to the DHCP server and obtains a particular reserved IP address from the DHCP server via an exchange of DHCP messages between that virtual machine and the DHCP server, and (ii) operates as a networked standalone computer using the particular unique MAC address and the particular reserved IP address.

In a storage system having a source storage system and target storage system, systems and methods maintain information from which a set of source data files stored on a storage system can be retrieved. In one embodiment, baseline images of one or more source data files are stored in target files of the target storage system. For a selected target storage time, locations in the source storage system where changes have been made since a previous target storage time are dynamically identified. Contents that occupy the locations are read and sent to the target storage system. The contents are stored in the target storage system together with associations of the contents with the locations.

In a data storage system having a plurality of storage nodes storing replicas of stripes, one storage node serves as a primary stripe node for a stripe. Client applications using the data storage system request operations affecting metadata stored in the stripe, and the data storage system creates workflow objects to implement the requested operation. Once the operation is completed, the workflow is acknowledged. A method for establishing a new primary stripe node comprises performing, by a selected storage node, a feasibility determination to determine the feasibility of the selected storage node becoming the new primary stripe node. It is feasible to become a new primary stripe node when doing so does not cause workflows that have been acknowledged, or that will be acknowledged, to result in strays.

Methods and apparatus are provided for preserving electronic resources identified as search results in a system location, such as a system folder. In one embodiment, a computer-implemented method comprises executing a search query on a data collection to produce at least one search result, the search query specifying at least one criterion, each of the at least one search results representing a resource which satisfies the at least one criterion; providing an input mechanism by means of which a user may select at least one resource for preservation; and executing, in response to the user's selection, a command to preserve the selected at least one resource in a system location.

A system for backing up desired data includes a communication link configured to transfer information between the system and a backup storage for storing backed up data, and a processor coupled to the communication link and configured to: determine associated substantive data of the desired data, compare the associated substantive data of the desired data with stored data, and transfer the associated substantive data over the communication link for storage based on the comparison of the associated substantive data with the stored data.

Automated systems and processes for managing paper and/or digital files, particularly medical records contained in digital files, digital or paper file folders and the like, in a file storage system having a finite size or expansion capacity. For paper files, a system tracks the thickness of individual file folders, the capacity of storage shelf sections, and the percentage of free space remaining in each shelf section. When occupied shelf space exceeds a threshold percentage for a shelf section, file folders are purged according to the likelihood that certain files will not be requested in the future, by applying purging algorithms to the files. For digital files, when a cumulative amount of storage space consumed by digital files reaches a certain threshold, typically less than the capacity, digital files are purged from the storage allocation according to an algorithm assessing a likelihood that certain files will not be requested in the future.

In some embodiments, techniques for self-labeling to extract a representative set of samples from a large-scale set of unlabeled documents (e.g., a set that represents a distribution of the large-scale set) are provided. The samples of the representative set may then be used to classify the documents of the large-scale set.

A method of remediating a media asset comprising a magnetic tape includes preliminarily cleaning the media asset, treating the media asset, and finally cleaning the media asset. Treating the media asset includes baking the media asset, determining whether adjacent layers of the tape are stuck to each other, and re-baking the media asset. If adjacent layers of the tape are stuck to each other, the method includes submerging the magnetic tape in a cleaning bath for a predetermined period of time, unwinding the magnetic tape from a supply reel to a take-up reel at an unwind speed while drying the magnetic tape, and rewinding the magnetic tape onto the supply reel at a rewind speed before re-baking the media asset.
