Glossary-13
volume expiration time
The date and time on which a
volume
in a
volume set
expires. Oracle Secure Backup
computes this time by adding the
write window
duration, if any, to the
volume
creation time
for the first volume in the set, then adding the volume
retention period
.
For example, assume that a volume set belongs to a
media family
with a retention
period of 14 days and a write window of 7 days. Assume that the
volume creation
time
for the first volume in the set was January 1 at noon and that Oracle Secure
Backup subsequently wrote data on 20 more volumes in the set. In this scenario, the
volume expiration time for all 21 volumes in the set is January 22 at noon.
volume ID
A unique alphanumeric identifier assigned by Oracle Secure Backup to a
volume
when it was labeled. The volume ID usually includes the
media family
name of the
volume
, a dash, and a unique
volume sequence number
. For example, a volume ID in
the RMAN-DEFAULT media family could be RMAN-DEFAULT-000002.
volume label
The first block of the first
backup image
on a
volume
. It contains the
volume ID
, the
owner's name, the
volume creation time
, and other information.
volume sequence file
A file that contains a unique
volume ID
to assign when labeling a
volume
.
volume sequence number
A number recorded in the
volume label
that indicates the order of volumes in a
volume set
. The first
volume
in a set has sequence number 1. The
volume ID
for a
volume usually includes the
media family
name of the volume, a dash, and a unique
volume sequence number. For example, a volume ID for a volume in the
RMAN-DEFAULT media family could be RMAN-DEFAULT-000002.
volume set
A group of volumes spanned by a
backup image
. The part of the backup image that
fits on a single
volume
is a
backup section
.
volume tag
A field that is commonly used to hold the
barcode
identifier, also called a volume tag,
for the
volume
. The volume tag is found in the
volume label
.
wallet
A password-protected encrypted file. An Oracle wallet is primarily designed to store
X.509 certificates and their associated
public key
/
private key
pair. The contents of the
wallet are only available after the wallet password has been supplied, although with
an
obfuscated wallet
no password is required.
Web tool
The browser-based GUI that enables you to configure an
administrative domain
,
manage backup and restore operations, and browse the backup
catalog
.
write window
The period for which a
volume set
remains open for updates, usually by appending an
additional
backup image
. The write window opens at the
volume creation time
for
the first
volume
in the set and closes after the write window period has elapsed. After
the
write window close time
, Oracle Secure Backup does not allow further updates to
