Restoring data by using DSN1COPY

You can use the DSN1COPY utility to restore data that was previously backed up by the DSN1COPY utility or by the COPY utility. If you use the DSN1COPY utility to restore data or move data, the data definitions for the target object must be exactly the same as when the copy was created.

About this task

You cannot use the DSN1COPY utility to restore data that was backed up with the DFSMSdss concurrent copy facility.

Be careful when creating backups with the DSN1COPY utility. You must ensure that the data is consistent, or you might produce faulty backup copies. One advantage of using COPY to create backups is that it does not allow you to copy data that is in CHECK-pending or RECOVER-pending status. You can use COPY to prepare an up-to-date image copy of a table space, either by making a full image copy or by making an incremental image copy and merging that incremental copy with the most recent full image copy.

Keep access method services LISTCAT listings of table space data sets that correspond to each level of retained backup data.
