Weekdays 3AM Snapshot Policy
============================

Introduction
------------

This snapshot policy is designed to create automatic local snapshots of your drive every weekday at 3:00 AM UTC.
It uses a simple weekly retention strategy, ensuring that only the most recent three weeks of weekday snapshots are kept.

Scheduler Configuration
------------------------

- **Schedule**: Snapshots are taken Monday through Friday at 03:00 AM (UTC).
- **Time Zone**: UTC (`Etc/UTC`)
- **Retention Rule**:
  - Keep all weekday snapshots from the last 3 weeks.
  - Snapshots older than 3 weeks are automatically deleted.

Snapshot Timeline (1 Year)
--------------------------

- Snapshots are created 5 times a week (Monday–Friday).
- With the 3-week retention rule, only the most recent 15 snapshots are kept at any time:

::

  3 weeks × 5 days/week = 15 retained snapshots

- Older snapshots are automatically removed on a rolling basis.
