> For the complete documentation index, see [llms.txt](https://docs.payfacto.com/payfacto-knowledge/llms.txt). Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.payfacto.com/payfacto-knowledge/maitred-pos/maitred/maitred-complete-online-documentation/chap-6-system-configuration/backup/save-full-system.md). # Save Full system ### Save Full system The "Save Full System" option from the Backup menu, allows to save on an external media the entire database files, and sales totals. This function performs a complete copy and should be run at least once a week, especially if there is no backup hard drive. "Back-Office" saves the information in the same manner as the "End of Day" option. This operation does not replace the invoice archive information. This option should be used in addition to the "Save Checks to Disk" option. The Save Full System function copies all files with the extension .DAT from the Data folder to the external media. --- # 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.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.payfacto.com/payfacto-knowledge/maitred-pos/maitred/maitred-complete-online-documentation/chap-6-system-configuration/backup/save-full-system.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.
