In the context of Recovery Point Objective (RPO), which strategy is most effective for minimizing data loss?

Question

Options

• AIncreasing the interval between backups
• BReducing the interval between backups
• CRelying solely on physical backups stored offsite
• DUsing only one form of backup method for simplicity

• A
  4% (1)
• B
  72% (18)
• C
  8% (2)
• D
  16% (4)

Explanation

Reducing backup intervals directly shrinks your RPO because RPO measures the maximum acceptable data loss expressed as time - the less time between backups, the less data you can lose if a failure occurs. If backups run every 15 minutes instead of every 24 hours, a disaster can only erase at most 15 minutes of work rather than a full day.

• A is wrong because increasing the interval widens the window of potential data loss, moving RPO in the wrong direction.
• C is wrong because relying solely on offsite physical backups ignores other backup tiers and doesn't inherently address frequency - location strategy affects recoverability, not data loss volume.
• D is wrong because using a single backup method creates a single point of failure; best practice is a layered approach (e.g., 3-2-1 rule), and simplicity doesn't reduce RPO.

Memory tip: Think of RPO as a leash length - the shorter the leash (interval), the less your data can wander away before you can pull it back.
