Resolution

A HiDRO task or operation refers to the execution of a single command. The single command may back up one minidisk or shared filespace, format one minidisk, or create a single report on data in the catalog.

A HiDRO job refers to a collection of HiDRO tasks, operations, or commands. Normally, this collection is a logical set of tasks. For example, a job may be a set of backup commands, one for each minidisk or filespace that is to be backed up weekly at a site, or a set of commands needed to restore a user minidisk to a certain date and time.

When you are using the catalog operation, it is also important to understand the difference between an operation and a function.

HiDRO allows you to perform seven operations: backup, restore, copy, duplicate, format, verify, and catalog. The catalog operation has eight functions: condense, delete, display, reclaim, report, restore, update, and verify.

The catalog restore and verify functions generate commands that perform restore and verify operations with information that the functions take from the HiDRO catalog.
