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.

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.
