Since natural calamities and accidents can harm mission-critical data, businesses look for ways to recover data securely. Every organization is searching for better ways to retrieve valuable data when there are disasters. At the same time, establishing a data recovery set-up may be out of the question because of the costs involved. So, the public cloud is considered to be the next big thing for data recovery and backups.

1. The best part about choosing the public cloud is that it provides additional resources in real time. It can offer unlimited storage and is highly flexible. It is possible to add resources as and when required. But where data recovery or data backups are concerned the best performance is guaranteed by using the on-site resources.

2. When you consider the local resources to be your primary defence, your secondary defence is then the public cloud. It is essential to identify the data and services which are needed for daily operations of a business. You must also understand the dependencies of such services and ensure that these are well protected in public clouds.

3. It is not enough to consider traditional backups only for disaster recovery. There is always the possibility of huge disasters and loss of many servers. You will need to carry out many data recovery operations to prevent data loss or application crashes. These may have been because of file over-writing or file deletion by accident. In such instances, you may not notice the data loss right away. Besides the traditional backups that you carry out, it may be useful to conduct multiple snapshot copies of the data. These image-based backups help to replace traditional backups. So, you can benefit from many recovery points. This will allow you to retrieve data, regardless of the time frame. You can recover data from a few minutes ago to data stored last week. Replication technologies can protect data continuously both on-site and in the public cloud. But this should not be viewed as total replacement for backups. Backups of the storage and systems can protect data on the operating system. This is helpful when you must recover the whole environment. But if you want to protect any service like the Microsoft Exchange, you may want to restore either a single mail or one mailbox. This means that you should understand data you need to restore to ensure you carry out backups which will help you do this.

4. With virtualization, you can do backups at hypervisor levels of VMs. However, this backup restricts data recovery to a virtual machine level only. To get the best restoration, you may need to run backup agents to avail of rich services within VMs.

5. One of the main reasons why data must be stored is for long-term archiving. This archiving is useful for business needs and regulatory requirements. But maintaining the backups on company resources is expensive. So, if you can archive the outdated and less-used files in public clouds, it may be cost-friendly.

6. Keeping the company data secure is mandatory for most businesses. When you choose to store the backups in a public cloud, you need to find out about its security solutions. This means that you should look into the physical security for these clouds. You should consider their data encryption techniques and the logical separation of company data from other businesses which may be using the same public cloud hosting provider. It is imperative to find out the way in which data is sent to the cloud and the encryption used for its protection.

7. In case you lose a whole website, you can always depend on backups of data and systems. However, it is important to know where to store data and OS if such a situation was to arise. You must consider running your systems in the public cloud using data and systems that have been backed up here. This will guarantee that your website is up and running without a private data center.

8. Businesses which use public clouds for backups often maintain local backups too. These companies should consider using one solution to support hybrid models which demand a unified management approach.

9. Finally, you must test the processes on a regular basis to be sure that these work properly and data is protected.

So, whether you own data backup services on-site or in a cloud, public clouds remain the best place for data recovery and backups. Rather than buying resources when disaster strikes, cloud hosting lets you enjoy long-term storage for affordable rates. Businesses can save costs and they get guaranteed data recovery much faster than recovery from tapes.
