# backup interval

## Syntax

```
[no] backup interval <seconds>
```

## Syntax Description

<table><thead><tr><th width="203">Keyword</th><th>Description</th></tr></thead><tbody><tr><td><code>no</code></td><td>(Optional) Returns the backup interval to its default value.</td></tr><tr><td>seconds</td><td>The interval at which the backup file should be written, in seconds.</td></tr></tbody></table>

## Defaults

The interval defaults to 3600 seconds (1 hour).

## Usage Guidelines

This command determines how often automatic system backups will be performed.&#x20;

The system aligns the start time for the backup process relative to midnight on the day the command is issued or the system reloaded. For example, if the interval is set to 8 hours, backups will occur daily at 12 AM, 8 AM, and 4 PM every day. If the interval is set to 18 hours, backups will occur at 12 AM and 6 PM on the first day, and 12 PM and 6 AM on the second day, then repeat.

Refer to the [Command Scheduler](/island-router-cli-2.3.2/command-scheduler.md) section for more information.

## Examples

```
backup interval 86400
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.islandrouter.com/island-router-cli-2.3.2/commands/backup/backup-interval.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
