Introduction

Personal data is scattered across mobile phones, computers, and various cloud drives. Common practices include “copying important folders to a hard drive” or “enabling cloud sync.” However, during hard drive failures, accidental deletions, account anomalies, or local disasters, single-point backups often fail to meet recovery demands. While one can research the 3-2-1 rule online, translating data classification, tool selection, automated tasks, and recovery verification into an executable checklist still requires significant time to align context.

Below is an introduction to the SkillHub community Skill “Data Backup Plan” (@user_70c2f807/data-backup-plan). It converges backup solution design into a SKILL.md workflow that Agents can follow: inventorying data and devices within the conversation and outputting a structured plan through fixed steps, rather than discussing concepts in generalities.

What is this

“Data Backup Plan” is a data protection guidance Skill designed for personal and household scenarios. It is maintained by the community publisher user_70c2f807, currently at version 1.0.0, categorized under it-ops-security, and sourced from the community. The platform marks it as requires_api_key=false; once installed, the Agent executes it according to the skill documentation without relying on additional API keys.

The Skill solves the following problem: Given data types, devices, budget, and technical proficiency provided by the user, it designs a backup strategy adhering to the 3-2-1 rule. It covers tool recommendations, automated backup configuration concepts, verification and recovery testing, and cost-reliability trade-offs. The documentation explicitly states that it does not cover enterprise-level backup and disaster recovery systems.

Core Features

The following capabilities are derived from the instructions within the skill package’s SKILL.md.

  1. Strategy Design: Formulate backup strategies based on the 3-2-1 principle (3 copies of data, 2 types of media, 1 copy offsite).
  2. Tools & Services: Recommend backup tools and cloud services based on different needs, evaluating reliability and cost.
  3. Automation: Guide the configuration methods for automated periodic backups.
  4. Verification & Recovery: Develop backup verification and recovery test plans (including rhythms such as monthly checks, quarterly sample recovery, and annual full recovery tests).
  5. Encryption & Privacy: Guide the encryption of backups for sensitive data and emphasize key management.
  6. Structured Delivery: Output sections such as “Data Classification Table,” “Cloud/Local/Offsite Plan,” “Verification Plan,” and “Budget Estimation” based on fixed templates.

The built-in execution steps of the skill are: Data Inventory → Strategy Design → Tool Selection → Auto Configuration → Encryption Protection → Periodic Verification.

Installation & Activation

Method 1: Let the Agent execute via official installation documentation

The installation prompt provided on the SkillHub page is: First read SkillHub Installation and Priority Source Configuration, then install the coordinate @user_70c2f807/data-backup-plan.

Method 2: Use the skillhub CLI

First, confirm that the CLI is installed on the local machine:

command -v skillhub && skillhub --version

If not installed, follow the official documentation for a complete installation (the example below is the recommended one-click script):

curl -fsSL https://skillhub-1388575217.cos.ap-guangzhou.myqcloud.com/install/install.sh | bash

When installing the skill, you must use --dir to point to the current Agent’s skills directory; community packages require a namespace, otherwise, they may fail to download correctly from the index. Example:

skillhub install data-backup-plan --namespace user_70c2f807 --dir ~/.cursor/skills/

Common client skills directories (excerpted from official installation documentation):

  • Cursor: ~/.cursor/skills/
  • Claude Code: ~/.claude/skills/
  • Codex: ~/.codex/skills/ or .agents/skills/ under the project

After installation is complete, restart or refresh the Agent according to your client’s requirements to ensure the new Skill is loaded.

Typical Usage

The quick start convention in the skill documentation is: After the user requests the use of “Data Backup Plan,” the Agent first collects four types of information and then outputs the plan.

  1. Most important data types (photos, documents, code, finances, etc.).
  2. Device status (mobile phones, computers, tablets, etc.).
  3. Budget range and technical proficiency.
  4. Generate a complete backup plan based on the above inputs.

Conversation example (excerpted from skill documentation):

User: Help me use the “Data Backup Plan”

Assistant: Sure, please tell me your specific situation. Please first specify: your most important data types, existing devices, budget, and technical proficiency. I will then provide a three-tier plan—cloud, local, and offsite—and a verification plan based on the 3-2-1 principle.

The output follows the template within the skill, for example including:

## Data Backup Plan

### 3-2-1 Principle
- 3 copies of data (Original + 2 backups)
- 2 types of storage media (e.g., Hard Drive + Cloud)
- 1 copy offsite storage (e.g., Cloud / Relative's place)

### Data Classification and Backup Strategy
| Data Type | Importance | Backup Frequency | Backup Method |
...

FAQs and error handling tables (e.g., extremely low budget, TB-level data volume, low technical proficiency, backup already lost, etc.) constrain the Agent’s response direction to prevent the plan from deviating from practical constraints.

Scenarios & Notes

Who is it for

  • Those who need to establish an executable backup checklist for personal or household data, rather than a one-time file copy.
  • Those who want the Agent to enforce the completion of inventory, tiered backups, and verification rhythms in conversation, rather than just explaining the 3-2-1 definition.
  • Lightweight IT self-service scenarios under the Operations/Security category (Platform classification: it-ops-security).

Limitations & Pitfalls (from the skill documentation’s “Important Limitations” and “N/A Scenarios”)

  • The plan needs to be adjusted based on data importance and budget; a backup that is not verified is equivalent to no backup.
  • Relies on the stability of the network and cloud service providers; encrypted backups require secure key management.
  • Does not cover enterprise-level backups, data center architecture, backup product development, or compliance retention needs.
  • Common misuses include: relying only on single-point backups, never checking automated tasks, never performing recovery tests, or losing passwords after encryption.

Conclusion

“Data Backup Plan” transforms personal backups from principle explanations into deliverable tabular plans and verification schedules. It is suitable for hanging on Agents that support Skills, such as Cursor, to quickly align strategies when organizing photo albums, switching devices, or expanding storage.
