2.7 The Virtual Copy Repository

3PAR Recovery Manager records important information for each virtual copy taken by the

Recovery Manager utilities. The information is used by Recovery Manager for database

restoration. The information is stored in the repository at:

/etc/3par/solutions/<db_host>.ora.<oracle_sid>/<timestamp>

2.7.1 The Virtual Copy Repository Removal Utility

3PAR Recovery Manager’s virtual copy repository removal utility removes a virtual copy’s

repository that was created using the create utility (

2.6.2 The Virtual Copy Creation Utility

on

page 2.7). The virtual copy that has been removed must have

Removed

status in order for

Recovery Manager to remove the repository. The status of a virtual copy can be obtained using

the display utility (

2.6.3 The Virtual Copy Display Utility

on page 2.9).

If a virtual copy has been backed up, the remove repository utility command fails unless the -f

option is used.

2.8 Virtual Copy Policy

3PAR Recovery Manager provides the capability to limit the maximum number of virtual copies

allowed per database instance at any time.

For example, a policy can be set to only allow twelve virtual copies at any time for a database.

Recovery Manager always maintains the twelve latest virtual copies by removing the oldest

virtual copy before creating a new copy. If a virtual copy is protected by retention time, it can

only be removed after the retention time ends. The default and maximum allowed number is

500, meaning that up to 500 read-only virtual copies can be created if you have sufficient

snapshot space.
