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
