VPS Backup Strategy: Full Backup or Incremental Backup?

Many VPS users take backups, but because they don't use the right backup strategy, they either incur unnecessary disk costs or their data recovery time is far too long. Choosing the right backup strategy is based on balancing storage cost + backup time + restore time + data loss risk (RPO).
