When you use Data Disaster Recovery to back up data, you are charged based on the backup data size.
Subscription (upfront)
Data Disaster Recovery provides several backup plan specifications. Each specification offers a different free data quota, pricing, and backup and recovery performance.
Subscription (upfront) billing = Base fee for the specification + (Actual data volume - Free quota data volume) × Overage rate
For example, Company A has a 150 GB database and plans to perform four full backups per month. The estimated total backup volume for the month is 600 GB (150 GB × 4). Company A can choose from the following three specifications (prices are for regions in the Chinese mainland):
micro (Entry-level) cost = USD 5 + (600 GB - 40 GB) × USD 0.117/GB = USD 70.52
small (Low-spec) cost = USD 22 + (600 GB - 400 GB) × USD 0.055/GB =USD 33
medium (Mid-spec) cost = USD 35 (No overage fees are charged because the actual data volume is less than the free quota.)
In this example, the small specification is the most cost-effective. If you need better backup and recovery performance, you can purchase a higher specification.
The following details the specifications:
Backup schedule type | Estimated time required to back up 100 GB of data | Free quota for data backup (GB per month) | Configuration fee for the Chinese mainland | Configuration fee for the China (Hong Kong) region and regions outside China | ||
Configuration fee (USD per month) | Unit price of excess backup data (USD per GB) | Configuration fee (USD per month) | Unit price of excess backup data (USD per GB) | |||
micro | 20 hours | 40 | 5 | 0.117 | 7 | 0.175 |
small | 5 hours | 400 | 22 | 0.055 | 33 | 0.083 |
medium | 2.5 hours | 800 | 35 | 0.039 | 53 | 0.059 |
large | 1.5 hours | 1600 | 56 | 0.024 | 84 | 0.036 |
xlarge | 1 hour | ∞ | 140 | Free of charge | 209 | Free of charge |
If the databases and tables that you want to back up involve issues such as unreasonable table schemas, large tables, or large fields, and you select a backup schedule of relatively low specifications, the resources of the backup schedule may be insufficient to back up the databases or tables and backup exceptions may occur.
In this case, we recommend that you select a backup schedule type with high specifications when you purchase the backup schedule, or upgrade the backup schedule to a type with higher specifications if an exception occurs, and then try again. If the issue still exists, you can join the DBS DingTalk group (ID 35585947) for technical support.
The fees displayed on the buy page prevail.
Higher specifications offer higher backup and restoration performance at lower unit prices. For more information, see Performance tests on backup and restoration.
You can only upgrade a backup schedule. You cannot downgrade a backup schedule. For more information, see Upgrade a backup schedule.
Each calendar month, you are allocated a free quota for data backup. If you do not use up the free quota within a month, the remaining free quota does not roll over into the next month.
If the total amount of data that you back up during a month exceeds the free quota, the excess data is charged based on the corresponding unit price.
