Backing up and restoring data with non-Db2 dump and restore

You can use certain non-Db2 facilities to dump and restore data sets and volumes. However, certain limitations exist.

About this task

Even though Db2 data sets are defined as VSAM data sets, Db2 data cannot be read or written by VSAM record processing because it has a different internal format. The data can be accessed by VSAM control interval (CI) processing. If you manage your own data sets, you can define them as VSAM linear data sets (LDSs), and access them through services that support data sets of that type.

Access method services for CI and LDS processing are available in z/OS®. IMPORT and EXPORT use CI processing; PRINT and REPRO do not, but they do support LDSs.

DFSMS Data Set Services (DFSMSdss) is available on z/OS and provides dump and restore services that can be used on Db2 data sets. Those services use VSAM CI processing.
