Database (CMMDB)
Change Journal | (Windows specific term) A Windows filesystem feature that logs | |
| a record of each change as it occurs to the files and directories | |
| on a local NTFS volume. | |
Change Log | (Windows specific term) A module that can be queried to | |
Provider | determine which objects on a filesystem have been created, | |
| modified, or deleted. | |
channel | (Oracle specific term) An Oracle Recovery Manager resource | |
| allocation. Every allocated channel starts a new Oracle process, | |
| which performs backup, restore, and recovery actions. The type | |
| of channel allocated determines the type of media used: | |
| • | type 'disk' |
| • | type ‘sbt_tape’ |
| If the specified channel is of type ‘sbt_tape’ and Oracle is | |
| integrated with Data Protector, the server process will attempt | |
| to read backups from or write data files to Data Protector. | |
chunking | (IAP specific term) The process of dividing data into blocks | |
| (chunks), where each chunk gets a unique content address. This | |
| address is then used to determine whether a particular chunk is | |
| already backed up to the IAP appliance. If the duplicate data | |
| is identified (two addresses are identical, that is the address is | |
| the same as for another data chunk already stored into IAP), it | |
| is not backed up. This way, the data redundancy is eliminated | |
| and the optimal data storage is achieved. | |
| See also backup to IAP. | |
circular logging | (Microsoft Exchange Server and Lotus Domino Server specific | |
| term) Circular logging is a Microsoft Exchange Server database | |
| and Lotus Domino Server database mode, in which the | |
| transaction log file contents are periodically overwritten after | |
| the corresponding data is committed to the database. Circular | |
| logging reduces disk storage space requirements. | |
client backup | A backup of all filesystems mounted on a client. Filesystems | |
| mounted on the client after the backup specification was created | |
| are not automatically detected. | |
