ICDA

(EMC Symmetrix specific term) EMC's Symmetrix Integrated

 

Cached Disk Arrays (ICDA) is a disk array device that combines

 

a set of physical disks, a number of FWD SCSI channels, an

 

internal cache memory, and control and diagnostic software

IDB

The Data Protector Internal Database is an embedded database

 

located on the Cell Manager that keeps information regarding

 

which data is backed up, on which media it is backed up, how

 

backup and restore sessions are run, and which devices and

 

libraries are configured.

IDB recovery file

An IDB file (obrindex.dat) with information about IDB backups,

 

media, and devices used for the backup. This information can

 

significantly simplify IDB recovery. It is recommended to relocate

 

the file, together with IDB transaction logs, to a separate physical

 

disk from other IDB directories, and, additionally, to make an

 

additional copy of the file.

importing media

A process that re-reads all data about backup sessions which

 

are on the medium back into the IDB. This then allows for fast

 

and convenient access to the data on the media.

 

See also exporting media.

incremental

A backup that selects only files that have changed since a

backup

previous backup. Several levels of incremental backup are

 

available, which enables detailed control of restore chain length.

 

See also backup types.

incremental

(Microsoft Exchange Server specific term) A backup of the

backup

Microsoft Exchange Server data that has changed since the last

 

full or incremental backup. With the incremental backup, only

 

the transaction log files are backed up.
