A weekly planning routine can fail even when no single file is lost. The calendar may belong to an old account, recurring events may import incorrectly, shared-calendar access may disappear, or a task list may be trapped on one device. A useful recovery plan begins with an inventory: every calendar, task list, planning document, account owner, shared participant, time zone, and device used during the weekly review. Mark which system is authoritative so a restored copy does not compete with the live schedule.
Preserve portable copies
Export calendars in their supported portable format on a regular cadence. Google Calendar exports calendar data in iCalendar format and includes fields such as start and end times, recurrence, title, description, location, invitees, and status: https://support.google.com/calendar/answer/10041132?hl=en-uk. A work or school administrator can restrict exports, so check that before relying on the feature. For a broader Google-account archive, Google Takeout can export supported product data without deleting the online copy: https://support.google.com/accounts/answer/3024190?hl=en. Save exports with the date and account name in a location independent of the planning account.
Keep a short continuity sheet
Once a week, make a readable snapshot covering the next two weeks: fixed appointments, deadlines, major tasks, contact details needed for meetings, and the next review date. Google Calendar can print a selected range or save it as a PDF, including descriptions and responses in schedule view: https://support.google.com/calendar/answer/41067?hl=en. This continuity sheet is not a replacement for the calendar. It is a temporary operating view if the account, app, or network is unavailable. Avoid putting sensitive meeting notes into an unprotected PDF.
Test imports without creating duplicates
Use a temporary calendar for restore drills. Google documents that ICS and CSV files can be imported on a computer, but guests and conference data are not imported, and imported events do not remain synchronized between accounts: https://support.google.com/calendar/answer/37118?hl=EN. Those limitations matter. Check recurring events, time zones, all-day events, descriptions, and exceptions to a series. Delete only the temporary test calendar after confirming the live calendar remains unchanged.
Make the weekly review resilient
Add five minutes to the normal review: confirm the account owner, export the latest calendar, refresh the continuity sheet, and note any shared calendars that disappeared. Once a month, import a small test file into a temporary calendar and compare it with the source. Record what the import omits. The plan works when another person, using the written inventory and exports, can reconstruct the next week without guessing.
