XCOPY › Basic Operation › Secondary FILES

Secondary FILES

XCOPY can be optionally set up to record all backup information into a separate files data set. Input index records are selected and located through the FILES DD statement, while output index records are recorded in the FILES through the OFILES DD statement. The data set allocated to the OFILES DD statement has the same format as the data set allocated to the FILES DD statement, and can be used by any other CA Disk function that normally uses the FILES.

The advantage of having a secondary files data set for disaster recovery is that it simplifies the recovery process. This FILES and all corresponding ARCHVOLS can be taken to a new location and used for individual data set restoration, or for full system recovery. Finally, by having a FILES that only contains information about offsite data, CA Disk will never attempt to restore data from an ARCHVOL outside the set of offsite ARCHVOLS.
