Security Center provides the feature of anti-ransomware for databases. You can use
the feature to create an anti-ransomware policy to back up data in your database.
If your database is intruded by ransomware, you can restore the data of your database
by using backups. This ensures that your workload runs as expected. This topic describes
how to create an anti-ransomware policy for a database.
Background information
If you use Alibaba Cloud Hybrid Backup Recovery (HBR) to back up the data in your
database, we recommend that you do not use the feature of anti-ransomware for databases
to back up the data in your database.
Prerequisites
A specific amount of anti-ransomware capacity is purchased. The permissions to use
anti-ransomware are granted. For more information, see Enable anti-ransomware
Procedure
- Log on to the Security Center console.In the left-side navigation pane, choose .
- On the Anti-blackmail page, click the Database extortion virus protection tab and click Create Policies.
- In the Database protection strategy panel, create an anti-ransomware policy for a database.
- In the Change database step, configure the following parameters and click Next.
Parameter |
Description |
Policy Name |
The name of the anti-ransomware policy. |
Type |
The method that you want to use to select the database. Valid values:
- Automatic identification database
The system automatically identifies the databases that are deployed on your server.
We recommend that you select this option.
- Manually enter the database
If the database that you want to protect is not displayed in the list of databases
after you select Automatic identification database, you can select this option and manually specify the database.
|
Database |
The database that you want to protect or the server in which the database resides.
|
Database type |
The type of the database that you want to protect. This parameter is required only
if you set the Type parameter to Manually enter the database. Valid values:
|
Account |
The username of the account that you can use to log on to the required database. The
account must have the permissions to back up data in the database. If you set the
Database type parameter to ORACLE, you do not need to enter the username or the password
of the database.
Notice You must enter the username and password of the database instead of the server.
|
Password |
The password of the account that you can use to log on to the database. |
- In the Protection Policies step, configure the following parameters and click Finished.
Parameter |
Description |
Protection Policies |
The anti-ransomware policy that you want to use. You can click Use recommendation strategy to use the recommended anti-ransomware policy that is provided by Security Center.
If the recommended anti-ransomware policy cannot meet your business requirements,
you can modify the policy.
|
Full backup strategy |
The interval at which full backup is performed, the days of a week on which full backup
is performed, and the point in time at which the full backup starts.
Full backup indicates that you back up all data that exists at a specific point in
time. Full backup is time-consuming and requires a large amount of anti-ransomware
capacity.
|
Incremental backup strategy |
The interval at which incremental backup is performed and the point in time at which
the incremental backup starts.
Incremental backup indicates that you back up only the data that is newly generated
or modified after the last full or incremental backup. Therefore, incremental backup
is time-saving and requires less anti-ransomware capacity.
|
Backup data retention time |
The retention period of the backup. |
Backup network bandwidth limit |
The maximum network bandwidth that is allowed during data backup. If you set this
parameter to 0, network bandwidth is unlimited.
|
After the anti-ransomware policy for your database is created, Security Center automatically
installs the anti-ransomware agent on your server, and the policy enters the Initializing state. After the anti-ransomware agent is installed on your server, Security Center
backs up data in your database based on the backup policy that is configured in the
anti-ransomware policy.
What to do next
After the anti-ransomware policy is created, you must precheck the database that is
specified in the policy. If the precheck is successful, you can back up the data in
the database. For more information, see Precheck a database.
After the anti-ransomware policy for your database is created, we recommend that you
monitor the status of the anti-ransomware policy. If the policy is abnormal, perform
troubleshooting at the earliest opportunity. For more information, see Troubleshoot the issues causing the abnormal status of an anti-ransomware policy for
a database
