2. Back up To Dos (Same as README.md Section 2 Data Collection, Storage, and Backup Process)

[KSMaster115]

Note: Master DB to store data only for last two months (max query is prev month)

• 2.1 ​Read JSON packets from all meters every half an hour and store it in In Memory Data

• 2.2 ​Every 2 hrs, Daily In Memory Data (data structure 1.2) is flushed into the Daily Recovery JSON (data structure 1.3) as a backup.

• 2.3 ​Every day, for every meter aggregate the day's consumption using the Daily In Memory Data (data structure 1.2)

• 2.4 ​Every day, for every meter update the Master Database (data structure 1.4) with the current day's date and the aggregated sum from step 1.

• 2.5 ​The Daily In Memory Data (data structure 1.2) is then flushed into the Master Database's previous_day field (data structure 1.4), resetting it for the next day's data collection.
