Answer
Backup frequency should follow change rate and recovery objectives, not habit. A workload that changes all day and supports customer-facing operations may need more frequent protection than a quieter environment that can tolerate a larger rollback window.
That is why buyers should anchor the discussion in recovery point objectives first, then ask how the software supports mixed schedules, incremental methods, offsite copies, and verification. A single nightly save may be enough for one workload and dangerously weak for another.
