hi,

QUESTION: Data integrity of client copy

ENVIRONMENT DESCRIPTION:  there are several clients on one PRD server，corresponding to  QAS server.  Backup and

Recovery one client and DON'T influence the other client.

STEP:  1.lock all of users in one client of PRD except myself, and the other clients are running normal.

             2.in one objective client of QAS, execute client copy (type SAP_ALL) from PRD corresponding  source client.  (avoid

DATA BACKUP)

             3.landing the source client on PRD server ,execute client copy (type SAP_ALL) from QAS corresponding client.

?????: there is NOT only one client on PRD server, i want recovery ONE client data and don't influence the other client

data,so i can't execute DATA BACKUP and DATA RECOVERY.  Does client copy could keep data integrity ?
