Offloading and Backing Up Datasets (TSIDOFL)

TSIDOFL backs up or offloads selected datasets according to the settings on an UPSI statement and the contents of control statements.

Control statements indicating which datasets are to be processed can be generated by TSIDOFD or specified manually. They are supplied as SYSIPT data. TSIDOFL sorts the control statements and copies the datasets to tape in order by descending dataset name and version number.

The offload tape is always associated with a cataloged dataset. You can use the default offload dataset OFFLOAD.DATA.SET, or you can create your own dataset. If you create your own dataset, you must catalog it and supply a TLBL or DD statement using the DTF name OUTPUT. The tape is retained until every dataset it contains has expired. If you want to retain the tape longer, you can specify special retention in the offload dataset's catalog entry.
