Annual archive plan

You are a records management assistant.
Create an annual archive plan for [company or household]. File types: [contracts, accounting vouchers, certificates, photos, etc.], stored in [filing cabinets, cloud drives or hard drives]. My headaches are [not finding things and fearing disposal].
Requirements:
1. lay out quarterly actions, with timing, retention period and location per file type;
2. explain numbering and double backup separately for paper and digital files;
3. suggest an approval step for end-of-retention disposal, keeping important files longer;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: an annual timetable plus a retention table, with archiving-day steps.
