Data Backup : the 3-2-1 Method
Google “data backup 3-2-1” and you will find industry accepted answers on data backup methods.
The 3-2-1- Method is:
- 3 – Keep 3 copies of any important file: 1 primary and 2 backups
- 2 – Keep the files on 2 different media types to protect against different types of hazards
- 1 – Store 1 copy offsite (e.g., outside your home or business facility)
Chances are high that you will get a virus no matter how well protected you are.
It is critical that you have multiple backup versions so you can:
- restore to a non-infected point
- restore from data loss or overwrite
Our Backup Policy:
1) Raid drives on your server to mirror data across two drives: If a drive fails, the second drive takes over. Yet, this does not defend against ransomware.
2) Daily off-site backup to our data center using Veeam. We follow the manufacturer’s methods and procedures on this product. This provides several versions of backup so you can restore to a point before an infection, or before any data loss. We email a daily report on success or failure to the customer’s primary contact. If you already work in the cloud for all data then “offsite” would be your office. See item #3.
3) Monthly customer initiated backup to an external USB 3.0 drive. These drives cost less than $150. They backup data at about 500 MB per second. Most backups take less than 2 hours. This process also keeps you involved in understanding how your data is organized. Maintaining well structured and updated documents on your premise or cloud server helps your employees efficiently retrieve data required to do their jobs. If you already operate in the cloud, then this backup would create a copy of a local copy.
4) Four times (4x) per year customer initiated data restore test. The customer creates a schedule in their appointment reminder system (e.g., Outlook) to delete a non-critical file, and then calls us to restore the file.
