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.
