Specifying the batch size primarily optimizes the performance of data export operations by grouping objects, not directly preventing accidental mass deletions.

Specifying the page size impacts how many objects are retrieved per query during an import, mainly affecting performance and memory usage, not preventing deletions.

This option, known as the deletion threshold, allows an administrator to define an acceptable number of deletions for a Management Agent run. If the actual number of detected deletions exceeds this threshold during synchronization, the run will automatically stop, preventing accidental or erroneous mass deletions from propagating to the connected HR data source and safeguarding critical identity objects.

Enabling the option to specify the number of objects to process limits the total objects processed in a run, which is not the specific control for preventing critical object loss due to mass deletions.
