Safeguarded Copy commands

Use this information to learn about commands available for Safeguarded Copy sessions.

The Safeguarded Copy function is currently only available on the DS8000 storage system.

Table 1. Safeguarded Copy commands
Command Action
Backup The Backup command creates a safeguarded backup for all volumes in the session, which is a point-in-time copy of the data on the safeguarded source volumes.
Recover Recovers the data in the designated safeguarded backup to the recovery volumes, for all source volumes that were part of the backup.
InitiateBackgroundCopy The Initiate Background Copy command is only available after a Recover.

Copies all tracks from the source to the target immediately, instead of waiting until the source track is written to.
Expire Backup Removes the designated safeguarded backup and all earlier safeguarded backups for the safeguarded source volumes in the session.
TerminateH1R1 Removes the H1R1 relationship that was created with the Recover command.
Refresh States

Refreshes the list of Safeguarded Copy backups on the session, and their recoverability status. The command queries all source volumes in the session for the list of existing Safeguarded Copy backups, as well as querying the latest state on the hardware for H1R1 recovery relationships.

You are not required to run this command under typical circumstances. Copy Services Manager refreshes the states of its sessions through multiple means. However, if you discover an inconsistency between Copy Services Manager and the hardware, you can use this command to enable Copy Services Manager to update itself.

Important: This command triggers multiple queries on the hardware, which can impact hardware performance. Do not run this command more frequently than every few minutes in each session.
Note: When adding new copy sets into a Safeguarded Copy session, the Refresh States command can be used to query the hardware for any existing backups that are associated with the source volumes. This action might result in the session going from a Defined state to a Protected state before a Backup command is issued.
Terminate Removes all active physical copies and relationships from the hardware during an active session.

If you want the targets to be data consistent before removing their relationship, you must issue the InitiateBackgroundCopy command if NOCOPY was specified, and then wait for the background copy to complete by checking the copying status of the pairs.
