obdrindex.dat

An IDB file 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, on a separate physical disk from other IDB directories, and, additionally, to make a copy of the file and locate it where you want.

OBDR capable device

Adevice that can emulate a CD-ROM drive loaded with a bootable disk and can thus be used as a backup or boot device for disaster recovery purposes.

object

An object can be one of the following:

•for Windows clients, an object is a logical disk (such as d:);

•for UNIX clients, an object is a mounted filesystem or a mount point;

•for Novell Netware clients, an object is a volume.

The scope of the data can be further reduced by selecting files or directories. Additionally, an object can be a database entity.

Object ID (Windows specific term) The object IDs (OIDs) enable access to NTFS 5 files no matter where in the system the files reside. Data Protector treats the OIDs as alternate streams of the files.
