We can use Repro for taking backup. Then what is the difference between Export and Rerpo?

EXPORT is normaly used to backup VSAM clusters/INDEXEs in a tape/other. and IMPORT is used to restore from the backups created by EXPORT.

Whereas REPORO .. will copy 1 file contents to another file with a replace option to replace any duplicate key records.

Hi,
The EXPORT command either exports a cluster or an alternate index or creates a backup copy of an integrated catalog facility catalog.Exporting means to store the cluster or AIX data in other media in a non-processable format, together with catalog information about the data set. Access Method Services acknowledge and preserve the SMS classes during EXPORT.

IMPORT is the opposite operation to EXPORT. Here, you reload the cluster or AIX data and recatalog its catalog information in an active catalog. You can only IMPORT a cluster that was previously EXPORTed.

The REPRO command can be used to copy and catalog a vsam cluster as well as non-VSAM data sets. It also can be used to unload and reload VSAM catalogs.

Hope this helps...
