VMware Backup: Why Choose a Public Cloud for Offsite Data Storage
The famous 3-2-1 backup rule suggests one must have 3 copies of data, on 2 different media, 1 of which is offsite. While backing up VMs to two different media is a piece of cake, offsite data storage is more challenging. Unless you already have a second site where you can put a server for your VM backups, arranging for an office or server space, setting up an environment, and paying rent, electricity, and Internet does not seem to be worth it. You can back up to disks or tape and send them offsite in the rotation, but honestly, that’s a bit of the Stone Age.
Where to Keep Offsite VM Backups?
Using a cloud as a backup destination can save your budget, as you can use your existing hardware instead of buying and configuring an offsite backup infrastructure. You also win from the maintenance perspective, as you don’t need to maintain a second location and its environment.
Backing up to a cloud can save your time, as you can use the “set it and forget it” approach instead of spending hours of your time babysitting tapes or disks and sending them offsite in the rotation.
Cloud backups are easier to manage: you can access your backups at any time and from anywhere. Because your data goes to a cloud, you can use Web-based tools to manage and monitor all aspects of data protection anytime from anywhere, even from home or on the go using your tablet.
A cloud can instantly adapt to your needs, as there’s no such thing as “not enough space” in the cloud. The moment you need it, you can have it. Instead of choosing, ordering, installing, and configuring a new server or hard drives you just need to make a few clicks.
Finally, and most importantly, backup in a cloud stays safe even if your infrastructure is hit by a disaster.
Despite the above advantages, there are some concerns that should be resolved before you decide and move to a cloud backup: what cloud to choose, how to ensure your backups are secure and no one can access them, and how to get cloud services at an affordable price.
For NAKIVO Backup & Replication, we have built an integration with Amazon EC2 cloud because Amazon is reliable, secure, and affordable. As a well-known and established cloud provider, Amazon’s Service Level Agreement states that the company is committed to delivering at least 99.95% monthly uptime for its services.
As of now, NAKIVO is the only vendor in the market that offers local, offsite, and cloud backup in a single product. We have designed the cloud integration feature so that it’s very simple to use: all you need to do is just sign up for Amazon and get credentials, and then specify in what region the repository should be created and how much space you need:
To ensure that your data is secure in the cloud, you can click More options and enable repository encryption (AES 256 bit encryption is used) and set up inbound firewall rules (so only you can access the backup repository). When creating a backup job, you can also select the “Encrypt data during transfer” option so that your data gets encrypted before the first bit leaves your premises.
While Amazon offers cloud storage at a truly affordable price, NAKIVO Backup & Replication also helps to reduce offsite backup costs with some of its features: backup jobs are forever incremental, so there’re no periodic full backups which consume bandwidth, Network Acceleration reduces the size of data that travels to the cloud (2x on average), global data deduplication and compression reduce the amount of space required to keep backups.
With NAKIVO Backup & Replication, you can back up your VMs to a reliable, secure, and affordable public cloud, and be sure that your data is safe, even if a disaster occurs.
