Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.islandrouter.com/island-router-cli-2.3.2/commands/backup/backup-url.md). # backup url Enables the automatic backup function and specifies the destination of the backup file. ## Syntax ``` [no] backup url ``` ## Syntax Description
KeywordDescription
no(Optional) Disables automatic backup.
urlSpecifies the backup file destination.
## Defaults No automatic backup is performed by default. ## Usage Guidelines The backup URL can refer to either a remote file or remote directory. If the URL ends in any character other than a slash (“/”), it is assumed to refer to a file name. The backup is written to that file, overwriting it if it already exists. If the URL ends in a slash, the system assumes it is pointing to a directory. In this case, the system will create a new file with the following format: hostname-YYYYMMDD-HHMMSS.backup. If the URL contains a password, it is encrypted so that it is not readable in the configuration file. Refer to the [URL Format](/island-router-cli-2.3.2/url-format.md) page for more information on the syntax of the url parameter. ## Examples ``` backup url scp://jane:d9fAq@192.168.38.7/myIsland.backup ``` ## Related Commands {% content-ref url="/pages/Kl3X0DmGIsO8Wgxjh9lM" %} [backup interval](/island-router-cli-2.3.2/commands/backup/backup-interval.md) {% endcontent-ref %} {% content-ref url="/pages/wl3PeTRIQ6etzpvmCOxq" %} [write network](/island-router-cli-2.3.2/commands/write/write-network.md) {% endcontent-ref %} {% content-ref url="/pages/2fW1ERxrRjivVw3P6iZP" %} [configure network](/island-router-cli-2.3.2/commands/configure-network.md) {% endcontent-ref %} --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.islandrouter.com/island-router-cli-2.3.2/commands/backup/backup-url.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. 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.
