System Administration
Your Sage 50 Accounting data is stored in a MySQL database. Each database consists of an SAI file that contains profile information about your company data, and a folder with an SAJ extension that contains your actual company data as well as user security information. Both the folder and the file are required to open your company in Sage 50 Accounting.

Your company records are indispensable. They help you invoice your customers, pay your expenses on time, and provide the information you need to plan for your business’ future. Because your company files do so much, you should take the time to ensure that your financial data is safe and secure. Creating a backup schedule is a great time-saver and will ensure consistent data backups.
By default, Sage 50 Accounting is set to verify that the company and security data in your backup files are intact and can be restored. If you make a mistake that you want to undo, or your files are damaged or accidentally deleted, then restore your data from your most recent backup. To learn more, search for How do I back up my company.
Tip: Sage 50 Accounting can remind you to back up your company data each time you close your company, or you can create a backup schedule to have Sage 50 Accounting automatically back up your data when you close your company file on the scheduled day.

When you create your company, Sage 50 Accounting automatically creates a user profile called sysadmin. This administrator has full rights to your company data.
When you create your company, there is no password protecting your files. It is a very good idea to add a password to ensure that your company data does not get changed without your knowledge. Once you add a password, you will be asked to enter it every time you open your company.
If you intend to access Sage 50 Accounting data from other programs, such as Microsoft Access, assign third-party access rights to sysadmin and then password-protect your data. To learn more, search for About passwords.

To add a password to your company data:
- On the Setup menu, select Change Password. Your User Name is always “sysadmin,” so you only need to remember your password to login.
- Enter your password twice and click OK.
