💾 Why You Should Backup Your Observations
1. Browser Storage Is Temporary
Your journal entries are stored in your browser’s local storage. While this allows offline access, browser storage can be cleared when you clear browser cache and cookies, when browser storage reaches its limit, during browser updates or system crashes, or when switching devices or browsers.
2. Backup Creates Permanent Records
Regular backups protect months or years of observations. Backup files are saved to your computer’s hard drive, not temporary browser storage.
- You can move your journal between computers, tablets, and phones using backup files.
- Keep multiple backup files to maintain a history of your observations over time.
- Restore your entire journal instantly if browser data is lost. JSON format ensures your observations remain readable for decades.
3. Backup Best Practices
- Backup after every observing session.
- Create weekly backups if you observe frequently.
- Store backup files in multiple locations such as your computer, cloud storage, and external drive.
- Name files with dates like
space_journal_2024-01-15.json. - Test restoration occasionally to verify backups work.
Note: The app will remind you to backup if it’s been more than 3 days since your last backup. Don’t ignore these reminders!
