How much storage do daily backups need?+

Roughly: number of fulls kept × data size + number of incrementals kept × data size × daily change rate, then reduced by compression.

What change rate should I use?+

Websites and file servers typically change 1–3% per day; busy databases 5–10%.

Does The PowerHost include backups?+

Free daily basic backups are included on cPanel-based plans (Shared, WordPress, Cloud). VPS backups are a paid add-on.
