data-selector

Description

The data-selector placeholder represents Oracle Secure Backup catalog data that is selected based on user-specified values.

Syntax

data-selector::=

latest | earliest | all | backup-id | date-time | date-range

Semantics

latest

Most recent. If the following conditions are met, then Oracle Secure Backup includes all backups on which the incremental is dependent up to and including the preceding full backup:

• The file system object is a directory.

• The most recent instance is an incremental backup.

earliest

Least recent. If the file system object is a directory, then Oracle Secure Backup selects the instance of the directory and its contents found in the earliest full backup.

all

All instances.

backup-id

The specific instance contained in the backup image section identified by backup-id. The backup ID is a small integer assigned by obtool for reference purposes only.

date-time

The file system object as it existed in a backup no later than the given date-time (see "date-time"). If the file system object is a directory, and if the most recent instance is an incremental backup, then Oracle Secure Backup includes all predicates (backups on which the incremental is dependent) up to and including the preceding full backup.

date-range

All objects backed up exactly between the two specified date-time values (see "date-range"). Unlike the single date-time expression, Oracle Secure Backup gives no special consideration to incremental backups of directories.
