Backblaze storage calculates at 99.999999999 (eleven nines) annual durability and 99.9% availability for its cloud storage services. A full copy is also faster to restore than one rebuilt from erasure-coded storage. In this case, the data durability is determined by the failure recovery model and replica organization strategy. Your trusted adviser for enterprise IT services: hybrid IT, cloud, digital transformation, data center, & consulting. This approach allows data to survive the loss or corruption of data in one or even multiple locations through accident, war, theft, or any manner of natural disaster or alien invasion.

If you have lower file volume, in the gigabytes or a few terabytes, durability is much less important, as losing a few bytes and corrupted files will be much smaller proportionally compared to a petabyte or exabyte environment. Deduplication is another way that copies can be kept without storing two complete duplicate versions of every file for every backup. Data on traditional spinning hard drive systems can degrade with time, have errors introduced during copying, or become corrupted in any number of ways. We’ve also described why it doesn’t really matter. When you create a storage account, you can select one of the following redundancy options: 1.
