- 3. What is Data Backup? Data backup is the act of copying critical organizational data to a secondary storage location. Data backup helps to protect businesses against data loss by providing redundancy to the primary storage location in case that location is compromised or fails.
- 4. Why we Backup? There are many reasons why your organization may want to back up their data. The primary reason is to recover data after its loss. The loss can occur by accidental deletion, a virus attack, or a software or hardware failure. If any of those things occur and your files are backed up, you can easily restore those files. Preventing events that result in loss of data is most desired, but backing up data provides the protection for data after a system failure. Individual computers being backed up are different than servers being backed up. Individual computer users can back up their own information when desired and using methods they desire, whereas data on organization servers need more formal backup procedures
- 5. Backup Steps: The Basics Find the files that you want to backup (documents, spreadsheets, databases, etc.) Copy the files to backup media (USB Drive, external drive, cloud storage drive, etc.) Repeat above at scheduled frequency. Note: This is a primary level of backup. Ideally, you should keep your files organized in folders for easy identification of files needing backup.
- 6. Backup Considerations Method: There are multiple methods of storing backup data. Some methods are described in the Methods of Backups section. What to Backup: There is a wide range of information that can be backed up. Files that are stored can be backed up on desktops, notebooks, laptops, and servers. In addition, data managed by applications you use such as email programs, client intake programs and other programs should also be backed up. An organization should discuss which information is most important. It is important that organization information be backed up whether it resides in the office, and/or on any home computers that people may be working on for office work.
- 7. Backup Considerations Frequency: Backups must occur regularly in order to prevent data loss. The more scheduled backups that take place the better off your organization. Frequent backups take time, money, and resources but the benefits outweigh these negatives. Storage Location: It is a good practice to keep some backup information offsite. In the event that a natural disaster occurs, your backup will mean nothing if it got destroyed with all the computers and the building.
- 8. Backup Considerations Security: Whether the backup data is onsite or offsite, you will want to ensure the backup information is secure and accessible only by those authorized to use it to restore lost data. Retention: The amount of history to be saved is another thing to consider. Depending on the nature of your business, you may want to keep backups that are years, months, weeks, or even just a day old. Keep in mind that the more backups you wish to save, the more space you will need to have (increased cost).
- 9. Methods of Backups You can setup regular backups of data in-house (locally), or via an external service (vendor). Locally-Managed Backups Many Windows operating systems such as XP and Windows 7 include Backup utilities for setting up regular backups of important files. There are also software packages (free and purchased) that can be used to backup data. In either case, wizards typically guide you through the process of setting up your backup, and include things such as designating the destination device for your backups (see options below), choosing the folders/files to be backed up, and specifying the frequency of backup. Keep in mind that if you use any of the non-cloud-based destination options for your backup data, it is advisable to keep a copy of the backup device contents in a secured location separate from the office.
- 10. Methods of Backups Backup Destination Options ● Flash storage or USB drives ● CD/DVD ● External hard drive ● Cloud storage
- 11. Methods of Backups Vendor-Managed Backups A backup service is another option where you pay companies that specialize in performing backups for you. Your data is stored on servers they own. Below is a list of some backup services.
- 12. Security Considerations for Backup Data Security attacks — whether in the form of malicious Internet content, theft of physical devices, login violations, or denials of service (meaning others are prevented from accessing your site) — can catch nonprofits off-guard, especially smaller and mid-sized organizations that may be unaware of possible threats, and unprepared to deal with them once they occur. Yet data leakage to the public, systems down-time, and reputation loss resulting from such security violations can easily turn away new and existing constituents if such situations are not handled appropriately and quickly. This may, in turn, impact on the organization’s reputation and future opportunities for growth. A computer virus outbreak or a network breach can cost an organization thousands of dollars. In some cases, it may even lead to legal liability and lawsuits. Because of these risks, you should ensure your backup data is protected against unauthorized access.
