An employee keeps another copy of an important file in a different location. What practice does this illustrate?

Correct answer: Creating a backup

The governing concept is backup and recovery in file management. A backup is a separate copy of data kept so that the original can be restored if it is accidentally deleted, corrupted, lost, or affected by device failure. Keeping it in another location can reduce the risk that one incident destroys both copies. A is correct; B removes data, C gives access to others but does not necessarily create a recovery copy, and D is unrelated.
