# Servers and operations
URL: https://synquic.tech/docs/cli/self-host.md

Manage servers, backup workflows, mail, and instance configuration.

These operations require an authorized connection to a self-hosted installation. Provider and
host permissions still apply in native mode.

## Servers

```bash
synq server list
synq server check srv_123
```

Use the [server reference](/docs/cli/reference/server) to register connections, install components,
set rate limits, and monitor a server. The [Servers API](/docs/api/servers) also exposes container,
Git credential, and tunnel operations. Start with the [server guide](/docs/guides/custom-servers)
for prerequisites.

## Backups and restores

The workflow has four parts:

| Step | Commands |
| --- | --- |
| Configure and verify storage | [backup destination](/docs/cli/reference/backup/destination) |
| Choose a source, schedule, and retention | [backup policy](/docs/cli/reference/backup/policy) |
| Inspect executions or prepare a restore | [backup run](/docs/cli/reference/backup/run) |
| Inspect, apply, or cancel a prepared restore | [backup restore](/docs/cli/reference/backup#synq-backup-restore) |

```bash
synq backup destination list
synq backup policy list --project proj_123
synq backup policy run policy_123
synq backup run list --project proj_123
```

Preparing a restore does not apply it. Inspect the returned restore session and confirmation
requirements before using the apply command. See [backups and restores](/docs/guides/backups-restore).

## Mail

Use [mail commands](/docs/cli/reference/mail) to provision or adopt a server, manage domains and
mailboxes, and inspect delivery health. The [email guide](/docs/guides/email-webmail) covers DNS,
relay configuration, and webmail. Mail commands currently require an HTTP context.

## Installation settings and data

Use [system commands](/docs/cli/reference/system) for instance settings, onboarding, filesystem
browsing, and data transfer. Settings have native SDK support; remaining setup and migration actions
require HTTP.

For moving an installation, follow [control-plane migration](/docs/guides/migrate-control-plane).
For moving a workload, follow [server-to-server migration](/docs/guides/server-to-server-migration).

## Reverse proxy

The [edge workflow](/docs/cli/edge) covers setup, domains, and traffic rules. Its complete options are
in the [edge reference](/docs/cli/reference/edge).
