Right now, we keep all the data inside of our system, from the day one.
Data: including but not limited to records of sign in/out. ip address, sick leave records, future events.
To protect the data, we backup them every day offsite.
The thing we are thinking is how to take care of these disabled accounts, or inactivated accounts.
There are two options for the account disabled one year ago:
1: Move them to the archived database
2: Delete them
When we have decision, will post it here.
