20090213490 | PASS-THROUGH MECHANISM FOR LINEAR TAPE LIBRARY - A pass-through mechanism that couples a first linear tape library string to a second linear tape library string is maintained. A first robotic assembly associated with the first linear tape library string places a tape from the first linear tape library string into the pass-through mechanism. The pass-through mechanism moves the tape to a position where the tape can be removed by a second robotic assembly associated with the second linear tape library string. The second robotic assembly removes the tape from the pass-through mechanism and places the tape into the second linear tape library string. | 08-27-2009 |
20090249474 | SYSTEM AND METHOD FOR ADJUSTING THE SECURITY LEVEL OF A REMOVABLE MEDIUM - A method of adjusting a security level of a removable medium, including receiving a unique identification (ID) of a removable medium, a name of a file being processed, and a requested operation, determining the security level of the removable medium, determining a security level of the file being processed, and one of increasing and decreasing the security level of the removable medium based on the determined security level of the file being processed. Further, security levels of removable media are mapped to security zones which are subsequently used to allow or prevent transportation of a removable medium inside or outside of certain boundaries. | 10-01-2009 |
20090254645 | SERVER-MANAGED POWER SAVING METHOD FOR AUTOMATED TAPE LIBRARIES AND DRIVES - A system of controlling tape drives within a tape drive library where a backup server utilizes client backup schedules and pending client restore requests to efficiently control the powering on and off of tape drives within a tape drive library. | 10-08-2009 |
20090278654 | Method of and System for Controlling Access to an Automated Media Library - A method of controlling access to an automated media library receives a request for access to the library from an individual having an identity. Access may include importing media to the library, exporting media from the library, and opening a locked door to a cabinet containing the library. If the access includes the importing media, the method moves a robotic media handler to a locked import/export station. If the access includes exporting media, the method moves the requested media to the locked import/export station. If the access includes the opening the door, the method takes a first inventory of the media in the library. The method authenticates the identity of the individual and determines an access level associated with the individual. If the access level is insufficient for the requested access, the method denies the requested access and issues an alert. If the access level is sufficient for the requested access, the method determines if the requested access requires a second authentication. If a second authentication is required, the method prompts the individual to perform the second authentication. If the second authentication is verified, the method logs the access by the individual and grants the access. If the access is granted and the access is importing or exporting media, the method unlocks the import/export station. If the access is granted and the access is opening the door, the method unlocks the door. The method closes and locks the import/export station a predetermined length of time after unlocking the import/export station. The method locks the door a predetermined length of time after unlocking the door and takes a second inventory of the media. The method issues an alert if the second inventory differs from the first inventory. | 11-12-2009 |
20090282203 | MANAGING STORAGE AND MIGRATION OF BACKUP DATA - A method and system for client backup data management and storage using virtual tape libraries (VTLs). A VTL controller executing a software method receives metadata that distinguishes among a plurality of different versions of backup data. The VTL controller determines a latest version of the backup data. The VTL controller determines a migration set of zero or more versions of the backup data. The latest version and any version included in the migration set are included in the plurality of different versions. The VTL controller determines that a storage of the latest version in a first storage medium (e.g., magnetic disk) of the VTL is complete. The VTL controller migrates the migration set to a second storage medium (e.g., magnetic tape) of the VTL if the migration set includes at least one version of the backup data. | 11-12-2009 |

If the access is granted and the access is importing or exporting media, the method unlocks the import/export station. If the access is granted and the access is opening the door, the method unlocks the door. The method closes and locks the import/export station a predetermined length of time after unlocking the import/export station. The method locks the door a predetermined length of time after unlocking the door and takes a second inventory of the media. The method issues an alert if the second inventory differs from the first inventory. | 11-12-2009 |
20100121825 | FILE SYSTEM WITH INTERNAL DEDUPLICATION AND MANAGEMENT OF DATA BLOCKS - A method for deduplicating and managing data blocks within a file system includes adding a deduplication identifier to each pointer pointing to a data block to indicate whether the data block is deduplicated, detecting duplicate data blocks, determining whether one of the duplicate data blocks has been deduplicated, when detected, determining that one duplicate data block is a master copy when it is determined that one duplicate data block has been deduplicated, selecting one of the duplicate data blocks to be a master copy when it is determined that the duplicate data blocks have not been deduplicated, and setting the deduplication identifier of the selected duplicate data block to indicate deduplication, and determining that the other duplicate data block is a new duplicate data block and setting the deduplication identifier of the other duplicate data block to indicate deduplication and directing the respective pointer to the master copy. | 05-13-2010 |
20110239097 | DATA DEDUPLICATION USING CRC-SEED DIFFERENTIATION BETWEEN DATA AND STUBS - Various embodiments for differentiating between data and stubs pointing to a parent copy of deduplicated data are provided. Undeduplicated data is stored with a first cyclic redundancy check (CRC) seed. A stub pointing to the parent copy of the deduplicated data is stored with a second CRC seed. Subsequent to reading the deduplicated data, the first CRC seed is associated with the undeduplicated data, and the second CRC seed is associated with the stub. A CRC check is performed using one of the first and second CRC seeds. If the CRC check is positive, an I/O operation is allowed to proceed. If the CRC check is negative, an additional CRC check is performed using another one of the first and second CRC seeds. | 09-29-2011 |
20130262422 | DATA DEDUPLICATION USING CRC-SEED DIFFERENTIATION BETWEEN DATA AND STUBS - Various embodiments for differentiating between data and stubs pointing to a parent copy of deduplicated data are provided. Undeduplicated data is stored with a checksum of an initial value as a first cyclic redundancy check (CRC) seed. A stub pointing to the parent copy of the deduplicated data is stored with an additional checksum of a differing, additional initial value as a second CRC seed. | 10-03-2013 |
20150058297 | ADDING COOPERATIVE FILE COLORING PROTOCOLS IN A DATA DEDUPLICATION SYSTEM - For adding cooperative file coloring protocols in a data deduplication system using a processor device in a computing environment, a preferred character is represented for file coloring in a file using a code selected from a multiplicity of codes that represent a variety of contexts. The original meaning of the preferred character is retained when representing the preferred character for the file coloring by the code selected from the multiplicity of codes. | 02-26-2015 |
