To lower the rate of ingested samples, you can either reduce the number of time series you scrape (fewer targets or fewer series per target), or you can increase the scrape interval. However, reducing the number of series is likely more effective, due to compression of samples within a series.

approximately two hours data per block directory. Again, Prometheus's local

CAUTION: Non-POSIX compliant filesystems are not supported for Prometheus' local storage as unrecoverable corruptions may happen. NFS filesystems (including AWS's EFS) are not supported. NFS could be POSIX-compliant, but most implementations are not. It is strongly recommended to use a local filesystem for reliability.
