Backup Office 365 Data: On-Premises vs Cloud
You all must be knowing that backing up Office 365 data is helpful for an organisation. But many are confused about would it be better to backup data on-site or use a cloud backup to export data? Many have used some exporter and migrators to export Office 365 mailbox to PST so as to use it in their local machines. But user don’t know the exact way so that they can backup Office 365 data.
What do you need from a backup?
In many cases, user will need to backup so that they can protect data from ransomware, malicious internal attack, employee error, third-party integrations errors, and accidental overwrites. User want to make sure that they meets the following SAFE criteria through the process of export Office 365 data to PST or cloud premises:
- Secure: Their data should be secure from all unwanted intrusion as well from each and every intentional or accidental destruction.
- Accessible: The data that is backup should be fast and easy to retrieve it Process
- Speed: Backup retrieval and storage should be fast so as to the backed up and retrieved with a minimal disruption to your business
- Easiness: The data backups need to be as easy as possible to ensure that your data will be backed up regularly. Ideally, the backup will be automated.
Using on-premises backup
If you decide to go with an on-premises backup, it will usually cost you a little more up-front, but it might wind up being cheaper in the long run. You’ll need the appropriate storage hardware (hard drives), and you’ll need to set it up to easily backup your data.
Expected Vulnerabilities: On-premises backup is susceptible to the following vulnerabilities:
- SecurityYour on-premises backup is only as safe as the hardware. Any portable hardware that can access the backups can also damage the backups, and all the normal hazards that apply to any computer equipment (user error, ransomware, natural disaster, flooding, smoke damage) apply to your backups.
- Ease of useThe more secure you make your backups, the less accessible those backups will be in the event of a data loss.
- SpeedThe speed of an on-premises backup is limited to the speed of the drive, the speed of the computer equipment, and the speed of the cables. More money can create a much faster and robust system, but cheaper systems are likely to suffer from lag.
- AutomationOn-premises backup is usually not automated, so it’s important that regular backups are performed.
Your IT department can mitigate a lot of these vulnerabilities, given the right tools and equipment. Cheap equipment, substandard tools, and poorly trained IT staff can make your on-premises backup bulky, insecure, and hard to use.
Using cloud backups
Cloud-based backups usually have a very low up-front cost, as they’re often based on a subscription model where you’re either charged on a monthly or a usage basis. For smaller companies without a dedicated IT department, cloud backups may be the easiest way to start making regular backups.
Possible Vulnerabilities: If you’re going with a cloud backup provider, there may be a big difference in the quality of service you receive. Higher-level backup providers usually have fewer vulnerabilities.
- SecurityBecause a cloud-based backup is online, it can be hacked. You can mitigate this risk by choosing a backup provider with strong security measures. The best backup providers will also duplicate your data on multiple servers so that a hardware problem with a single server won’t destroy your data.
- Offline AccessA cloud backup is only accessible when you’re online. If your Internet Service Provider gives you choppy or inconsistent service, a cloud backup may be difficult to access without a reliable Internet connection.
- Ease of SetupYour cloud backup solution may offer automated backups, but it could be difficult to properly setup your backups when you first start with a new service. Some backup service providers will walk you through setup with onboarding, but others are complicated to setup and offer little guidance.
Many companies will opt for a hybrid model. With a hybrid model, some data is backed up on local or network hard drives on the premises, some is backed up to a cloud, and some data may be backed up in both locations. A hybrid model offers increased protection against data loss, but it could expose your company to a higher risk for data breaches and theft. Because a hybrid model requires excellent data management skills, it’s best to discuss the options with your IT department to find ways to eliminate or lessen the risk.
We have covered the topic that will suggest you to use make a right decision weather to have on-Premises or cloud backup to related you conversion. But user can even use Office 365 Exporter to backup Office 365 to PST / EML / MSG files format to access them in offline mode.
