Issue/Introduction

Disk™ Backup and Restore BACKUPCC is essentially DFDSS DUMP CC -- processing data sets with Concurrent Copy capability (or Snapshot if source volume is a RAMAC Virtual Array). Some of the considerations are listed below.

  1. Performing CC operations against many large data sets when there is also a heavy update activity that can result in a shortage of storage.
  2. Disk™ Backup and Restore Fast Archive processing does not apply to BACKUPCC
  3. There is no member level Restore for PDSs/PDSEs processed by BACKUPCC.

Environment

Release: Disk™ Backup and Restore

Resolution

Before the backup process can begin, a synchronization point must be established to ensure the integrity of the data being backed up.

To create a synchronization point, follow these five steps:
1.Create and/or verify that the DSCL command stream with the action command BACKUPCC is ready for execution.
2. The online system that is targeted for BACKUPCC must be quiesced. This ensures that all data set I/O buffers are written to DASD.
3. Execute the BACKUPCC job created in step 1.
4. Verify that the INITIALIZATION COMPLETE message issued from ADSDI106 was sent to the SYSLOG. This message indicates to the online administrator that it is now safe to resume online processing.
5. Restart the online system.
