backup image
Glossary-2
backup image
The product of a backup operation. A single backup image can span multiple volumes
in a
volume set . The part of a backup image that fits on a single volume is called a
backup section .
backup image file
The logical container of a backup image . A backup image consists of one file. One
backup image consists of one or more backup section s.
backup job
A backup that is eligible for execution by the Oracle Secure Backup scheduler . A
backup job contrasts with a backup request , which is an on-demand backup that has
not yet been forwarded to the scheduler with the
backup --go
command.
backup level
The level of an incremental backup of file-system data. Oracle Secure Backup
supports 9 different incremental backup levels for file-system backup .
backup piece
A backup file generated by Recovery Manager (RMAN) . A backup piece is stored in a
logical container called a backup set.
backup request
An on-demand backup that is held locally in obtool until you run the
backup
command with the
--go
option. At this point Oracle Secure Backup forwards the
requests to the scheduler , at which time each backup request becomes a backup job
and is eligible to run.
backup schedule
A description of when and how often Oracle Secure Backup should back up the files
specified by a
dataset . The backup schedule contains the names of each dataset file
and the name of the media family to use. The part of the schedule called the trigger
defines the days and times when the backups should occur. In obtool , you create a
backup schedule with the
mksched
command.
backup section
A portion of an backup image file that exists on a single tape. One backup image can
contain one or more backup sections. Each backup section is uniquely identified by a
backup ID .
backup transcript
A file that contains the standard output from a particular backup dispatched by the
Oracle Secure Backup
scheduler .
backup window
A time frame in which a backup operation can be run.
barcode
A symbol code, also called a tag, that is physically applied to a volume for
identification purposes. Oracle Secure Backup supports the use of tape libraries that
have an automated means to read barcodes.
