Issue/Introduction

Can you use VM:Backup to back up VM:Account minidisks without quiescing them?

Resolution

You can use VM:Backup to back up these VM:Account minidisks without quiescing them:

The 191 (LOCAL) minidisk, containing the PROFILE EXEC, the VMACCT CONFIG file, and locally modified files

The 192 (RUNTIME) minidisk, containing program material

The 1C0 (CONTROL) minidisk, containing customer lists, project lists, and cost tables

To back up the VM:Account 1B0 (COLLECT) minidisk, select the QUIESCE option in the VM:Backup exception file. When the backup runs, VM:Backup looks to see if the quiesce user exit (VMBEXIT2) exists. If you choose to define this user exit, code the exit to issue return code 4 to allow VM:Backup to use the CP SMSG facility to quiesce the 1B0 minidisk. If the VMBEXIT2 user exit does not exist, VM:Backup uses the CP SMSG facility to ask VM:Account to quiesce the 1B0 minidisk.
