| COPY, DUMP, PRINT and RESTORE | z/OS V1R13 | Updated: Specifying X'FFFFFFF' (or 268435455) as the value for high cylinder on the TRACKS parameter causes DFSMSdss to use the end of the volume for the high cylinder value. | Release support. |
| COPY | z/OS V1R12 | Updated: New FCFASTREVERSERESTORE and FCFULLVOLUMERELATION keywords | Support for the fast reverse restore capability of the IBM®System Storage®DS8000® series |
| COPY, COPYDUMP | z/OS V1R12 | Updated: For backups to and from tape, and for backups on DASD when the backup data set is in the extended format, DFSMS now uses BSAM instead of EXCP to read from and write to DFSMSdss dump data sets during COPY processing. This allows DFSMSdss to support 256 KB blocks when writing to and reading from a tape. It also allows the subject of the COPY or COPYDUMP command to be an extended format data set. The data set also can be striped or compressed format. | Release update |
| DUMP | z/OS V1R12 | Updated: For backups to and from tape, and for backups on DASD when the backup data set is in the extended format, DFSMS now uses BSAM instead of EXCP to read from and write to DFSMSdss dump data sets during COPY processing. This allows DFSMSdss to support 256 KB blocks when writing to and reading from a tape. It also allows the subject of the DUMP command to be an extended format data set. The data set also can be striped or compressed format. | Release update |
| z/OS V1R12 | Updated: For the OUTDDNAME parameter, the default block size for output records that are written to tape is determined by obtaining the optimum block size for the device. The maximum is 262 144. | Release update | |
| RESTORE | z/OS V1R12 | Updated: For backups to and from tape, and for backups on DASD when the backup data set is in the extended format, DFSMS now uses BSAM instead of EXCP to read from and write to DFSMSdss dump data sets during COPY processing.
