Doc for dump logical dataset https://www.ibm.com/docs/en/zos/2.1.0?topic=dfsmsdss-dump-dataset-syntax-logical-data-set which should be reviewed for options you may need. You'll find RESTORE in this same manual. //STEP1 EXEC PGM=ADRDSSU //DUMPDD DD DSN=BACKUP.DSN,DISP=(NEW,CATLG), // SPACE=(CYL,(50000,50000),RLSE) //SYSPRINT DD SYSOUT=A //SYSIN DD * DUMP OUTDD(DUMPDD) - DS(INCL(DATASET.TO.DUMP)) - /* TOL(ENQF) WAIT(0,0) /* if you can't quiesce the dataset and accept the risks */ - COMPRESS /* or HWCOMPRESS */ /* >So what would be the recommended size to dump on a compressed dataset? Since it's a vsam dataset and you are compressing the backup to use as little space as possible. Additionally, ADRDSSU uses full track. Look at the options to see if there is anything relevant to your situation. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
