The price of Azure Backup is dependent on the size of each protected instance. Azure Storage is a separate charge. Customers have the flexibility to choose between
-
LOCALLY REDUNDANT STORAGE (LRS)
-
ZONE REDUNDANT STORAGE (ZRS)
-
GEOGRAPHICALLY REDUNDANT STORAGE (GRS)
-
READ-ACCESS GEOGRAPHICALLY REDUNDANT STORAGE (RA-GRS)
Block Blobs
For streaming and storing documents, videos, pictures, backups and other unstructured text or binary data.
Azure Backup Example
Assume a Windows Server that is used for file sharing of office documents and PDF files, which has a total file size of 400Gb.
Backup Protected Instance | 400Gb | US$10 for protected instance |
Storage Cost for the Full Backup | Locally Redundant Storage (LRS) | 400Gb x US$0.024 = US$9.60 |
Data Changes between Backup | 20% of Data | 0.2 x 400Gb = 80Gb |
Backup Schedule |
| 50 copies |
Total Disk Space required for a Backup Retention Period | 50 copies | 80Gb x 50 copies = 4000Gb |
Total Disk Space After Data Compression | 10% | 4000Gb x 0.9 = 3600Gb |
Storage Cost for the Incremental Backup | 3600Gb x US$0.024 = US$86.40 |
