None of these prices depend on how many mailboxes or tenants you protect. Mailbox and tenant counts are an honour rule, not a technically enforced limit: we trust you to buy the edition that matches how you use Restow. There is no per-user, per-seat or per-GB meter anywhere in Restow. See Your data is your data, the vendor comparisons, and the worked 5-year pricing math for why that is worth spelling out. For what each edition actually includes feature by feature, see features.

What "one-time purchase" means
- A license is verified offline by a signed key: no phone-home check, nothing that can remotely disable the software, and no subscription that lapses.
- All updates are included for as long as we actively develop Restow. If we ever stop, we will announce it at least twelve months in advance and publish the Business and Service Provider modules under the AGPL. Your installation then keeps running without a license key.
- Licenses include the software and all updates. No support is included.
Backup and restore are complete in every edition and never limited by price or a mailbox count: the editions differ by what's added on top, not by what's held back.
Licenses include the software and all updates. No support is included. Setup (migrating an existing tenant, or configuring a multi-tenant Service Provider install) is priced on quote, since it depends on what you're moving from and how big it is; it is not part of the license price above.
What's not for sale
There is no hosted Restow (yet) and nothing metered by usage. We will adjust this according to feature requests: if you need a hosted option, tell us. Restow runs on infrastructure you or your IT provider controls; see security and sovereignty on the overview page for what that means for your encryption keys and your storage. A live demo with synthetic data runs at demo.restowbackup.com; it resets every night.
Frequently asked
What does Restow cost?
Community is free. Business and Service Provider are one-time purchases for business customers only. Pre-sale price €476 net until general release. List price from release: €595 net. Service Provider: Pre-sale price €1,560 net until general release. List price from release: €1,950 net. There is no per-mailbox or per-user subscription anywhere in Restow.
What happens if Restow development ever stops?

Does a license include support?
No. Licenses include the software and all updates. No support is included. Setup work such as migrating an existing tenant is priced separately, on quote.
Is there really no mailbox or tenant limit?
Correct, and it is not technically enforced either: it is an honour rule. We trust you to buy the edition that matches how you use Restow, whether that is one mailbox or several thousand.
Who can buy Business and Service Provider, and where?
Business customers only, within the meaning of § 14 BGB, not consumers. At launch, sales are limited to the EU/EEA, Switzerland and the UK.
