Local backups aren't obsolete - far from it. If you have a hybrid cloud solution, there are still some major advantages to keeping some or all of your data backed up on site. Local backups are often better secured, more accessible, and faster to deploy in the event of an emergency. Additionally, in a hybrid solution, there may also be resources that need to be limited to the internal network.
Improving the Accessibility of Your Data
A local backup is inherently more accessible to your employees, especially in the event of a business disruption. Local backups also tend to be more reliable and less resource-consuming, as the system is being backed up over the same network. By always knowing where your local backups are, you can ensure the timely restoration and deployment of these backups when issues occur. You can also look through your backups for lost files and recover information as needed. If your cloud platform is inaccessible or Internet access has been disrupted, you will still be able to acquire your local backup copies to continue business.
Keeping Control Over Your Local Data
In a hybrid cloud solution, there will be certain information that you keep within your corporate network. In order to keep control over this information (and to keep it appropriately secured), it usually must stay within that internal network. By keeping local backups of privileged data, you ensure that all of the data is properly secured with the necessary protocols. If you have any security concerns related to the cloud, this only makes sense: otherwise you would be exposing your information regardless of your internal IT infrastructure.
Storing a Redundant Copy of Your Data
It's never a good idea to rely solely upon a single backup or type of backup. Local data backup can work in tandem with a cloud backup solution to make sure that you have the copies of your system and files that you need in the event that something goes awry. By keeping a redundant copy of your data, you will be able to restore your information even if one system is corrupted, if files have been overwritten, if backups haven't been processed correctly, or if the backups are otherwise inaccessible to you at the time of a data emergency.
Of course, cloud backup solutions are also valuable: they just aren't always the only solution that should be used to secure your data. Ideally, a hybrid solution should have a hybrid backup system: backups should be kept on both local storage and cloud storage, redundantly. This offers a dual system with the combined benefits of both and the drawbacks of neither.
