The list below is just ideas to think about. Then in the list below there is some suggestions on how often to do backup.
- Backup of the database backup from databases that are critical for the company to function.
- Backup of current data files that are critical for the operation of the company.
- Backup of accounting if you have it inside of your organization.
- Backup of user profiles.
- Backup of static data:
- Archived information.
- Images of servers and workstations for quick restore.
Here are a couple of options for how often to do backup:
- Daily backup of data 1-3 to a storage server.
- Daily backup of 1-4 to storage server.
- Daily backup of 1-3 and a weekly backup of 4-5.
- You have your own server in a cloud outside of your company (you can even own it) that is a backup domain controller etc that can be put back in place if something goes wrong. I would not buy an expensive server as it will only store data and not have any login functionality for more than 10 people if needed. I would run a daily backup of 1-3 and a weekly backup of 4-5. This option will be a complete start over if everything in your business burns down. The server would probably cost around $3000 for a cheap server and about $100-200/month for having it in a rack, internet service etc. Here is an example of a server that you can modify that would be sufficient for this purpose: Supermicro SDR-5018D-MTF server
Have a nice day!
