object
See backup object
Object ID (Windows specific term)
The object IDs (OIDs) enable access to
NTFS 5 files no matter where in the
system the files reside. Application
Recovery Manager treats the OIDs as
alternate streams of the files.
online backup
A backup performed while a database
application remains available for use.
The database is placed into a special
backup mode of operation for the time
period that the backup application
requires access to the original data
objects. During this period, the database
is fully operational, but there may be a
small performance impact and log files
may grow very quickly.
• For ZDB methods, backup mode is
required for the short period of the
data replication process only
(~seconds). Normal database
operation can then be resumed for
the rest of the backup process.
In some cases, transaction logs may also
have to be backed up to allow a
consistent database to be restored.
See also zero downtime backup
(ZDB).
ownership
The ownership of a backup determines
who can restore from the backup. The
user who starts an interactive backup is
the session owner. If a user starts an
existing backup specification without
modifying it, the session is not
considered interactive. In that case, if
the backup owner has been defined in
the backup specification, they remain
the session owner. Otherwise, the
session owner becomes the user who
started the backup in question. For the
scheduled backups, by default, the
session owner is for the Cell Manager,
the user that was specified during the
installation of the Cell Manager. It is
possible to modify the ownership, so
that the specific user becomes the
session owner.
pair status (HP StorageWorks Disk

A mirrored pair of disks can have
various status values depending on the
action performed on it. The three most
important status values are:
