tape library
Glossary-12
tape library
A medium changer that accepts Small Computer System Interface (SCSI) commands
to move a volume from a storage element to a tape drive and back again.
tape service
A Network Data Management Protocol (NDMP) service that transfers data to and
from secondary storage and allows the data management application (DMA) to
manipulate and access secondary storage.
TCP/IP
Transmission Control Protocol/Internet Protocol. The suite of protocols used to
connect hosts for transmitting data over networks.
time-managed expiration policy
A media family expiration policy in which every volume in a volume set can be
overwritten when it reaches its volume expiration time . Oracle Secure Backup
computes the volume expiration time by adding the volume creation time for the first
volume in the set, the write window time , and the retention period .
For example, you set the write window for a media family to 7 days and the retention
period to 14 days. Assume that Oracle Secure Backup first wrote to the first volume in
the set on January 1 at noon and subsequently wrote data on 20 more volumes in the
set. In this scenario, all 21 volumes in the set expire on January 22 at noon.
You can make a Recovery Manager (RMAN) backup or a file-system backup to a
volume that use a time-managed expiration policy.
trigger
The part of a backup schedule that specifies the days and times at which the backups
should occur.
trusted certificate
A certificate that is considered valid without validation testing. Trusted certificates
build the foundation of the system of trust. Typically, they are certificates from a
trusted
Certification Authority (CA) .
unprivileged backup
File-system backups created with the
--unprivileged
option of the
backup
command. When you create or modify an Oracle Secure Backup user , you associate
operating system accounts with this user. Unprivileged backups of a host run under
the operating system account associate with Oracle Secure Backup user who initiates
the backup.
volume
A volume is a unit of media, such as an 8mm tape. A volume can contain multiple
backup images.
volume creation time
The time at which Oracle Secure Backup wrote backup image file number 1 to a
volume .
