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

Provider

(Windows specific term) A module that can be queried to

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.
