Prerequisites

  • The Hybrid Workloads agent interacts with Volume Shadow Copy Service (VSS) to perform full backups. Ensure that the Volume Shadow Copy Service is not disabled.

  • The Hybrid Workloads agent uses Microsoft SQL Server Virtual Device Interface (VDI) for differential and transaction log backups.

  • The account used for SQL backups and restores must also have the CREATE DATABASE permission for successful restores from snapshots. If the account used for SQL backups and restores does not have the CREATE DATABASE permission, the restores may fail with the SQL7 error. For more information, see GRANT Database Permissions.

Note: As with any other third-party backup software, Druva interfaces with Microsoft Virtual Device Interface (VDI) to perform differential and transaction log, backups and restores. The SysAdmin role is mandatory for VDI backups and restores. If the user account used for SQL VDI differential backups does not have the sysadmin role, the backups will fail in the initial stages.  If differential and transaction log backups and restores are not required, sysadmin permissions are not required. For more information, see  SQL Server VDI backup and restore operations require Sysadmin privileges.

  • Druva recommends that you use the Microsoft’s native VSS provider. If you are using a third-party VSS provider, you must configure Hybrid Workloads agents to recognize this provider. 

  • Ensure that the SQL Writer Service on your MS-SQL servers is running. 
  • Ensure that the disk space on the drive where your shadow copy storage is located is adequate for the cumulative size of your databases. To know how you can configure VSS to write shadow copies to a separate drive, see Set VSS to write shadow copies to a separate NTFS volume. 
  • Ensure that you enabled Windows authentication for your SQL servers. For more information, see Change Server Authentication Mode.  
  • Ensure that the Local System account has permissions listed in the following table:
    SQL privileges.png
    Permission Description
    Sysadmin Required for SQL server backup and restores. 

Note: As with any other third-party backup software, Druva interfaces with Microsoft Virtual Device Interface (VDI) to back up and restore SQL Database Transaction Logs. To use VDI, SysAdmin role is mandatory. If  transaction log backups and restores are not required, sysadmin permissions are not required.
For more information, see  Backup (Transact-SQL), and  Restore  Statements (Transact - SQL)

  • If you want to perform log backups for the database, ensure that you set the databases to FULL RECOVERY mode. For more information about modifying recovery mode, refer to View or Change the Recovery Model of a Database.  
  • Druva supports backup of availability group databases in MS-SQL server 2012 onward since Microsoft introduced availability group in SQL 2012.
  • Ensure that you install Hybrid Workloads agent on all primary and secondary nodes in the availability group.
  • Ensure that you enable the Readable secondary option for the secondary nodes for successful backups from that node.
  • Ensure that all the nodes in an availability group must have the same Hybrid Workloads agent version installed on them.
  • If you want the Hybrid Workloads agent to run under a domain user account:
    • Ensure that the domain user is added under the local administrative group of the SQL server
    • Ensure that Hybrid Workloads agent and SQL Server VSS writer service log on using the same domain user account. (By default both services log on using the local system account.)
    • Ensure that Sysadmin right is assigned to the domain user in the SQL server.

Software requirements for NAS devices

Druva provides vendor-agnostic support for NAS devices. The supported protocol for SMB and NAS shares is as mentioned below. Druva can perform backup and restore provided your configuration adheres to the following  NAS proxy mappings.

Share type on the NAS device NAS device is mapped to Shares discovered
CIFS/SMB Windows NAS proxy CIFS/SMB
NFS Linux NAS proxy NFS
CIFS/SMB and NFS Windows NAS proxy CIFS/SMB
CIFS/SMB and NFS Linux NAS proxy NFS
CIFS/SMB and NFS Windows NAS proxy and Linux NAS proxy CIFS/SMB and NFS

Note: 

  • The NAS proxy must be version  4.8.16-98358 or later for share auto-discovery to work. 
  • Druva validates the NAS device credentials before adding the NAS device. Ensure that you have valid device credentials.
  • Druva supports Amazon FSx for Windows and Amazon EFS shares for backups and restores. You can protect Amazon FSx shares using a Windows proxy, and protect Amazon EFS shares using a Linux proxy.  For more information see Druva support for Amazon FSx for Windows and Amazon EFS
  • Druva supports Azure Files through SMB and NFS protocols via a NAS proxy. However, auto-discovery of shares is not supported as of now. For more information, see Add a NAS share.
  • Druva supports Nutanix Files through SMB and NFS protocols via a NAS proxy. For more information, see Add a NAS share.

Permissions for NAS auto-discovery

The IPC$ share must be accessible with the provided device credentials. Druva accesses this share to authenticate itself with the NAS device, after which it can discover the other shares on the device.

Software requirements for NAS proxy 

Since you install the NAS proxy on a Windows or Linux server, the server must comply with the following requirements.

Security considerations

One thing that is often overlooked when deploying a data protection solution is security. While Druva automatically handles the security of information in transit and at rest, there are other security mechanisms that organizations should consider for implementing beyond encryption when it comes to data protection. The following sections discuss the security considerations that organizations should take into account as they implement Druva for their data protection solution.

Roles and responsibilities 

To prevent privileged users from making unauthorized changes to resources within their organization, Druva supports the Role Based Access Control (RBAC) for separation of duties. This capability allows organizations to limit privileged user access to a predefined set of roles and data assets. This RBAC capability makes it possible to create ethical walls to enforce privacy, as well as implement a delegated administration structure to meet customers’ organizational, compliance, or security requirements. To add RBAC in your Druva deployment, see Manage administrators.

Global regulatory compliance 

As part of your data protection strategy, organizations need to take into account where they operate and what requirements they have on security and availability of the data.  With Druva , organizations can store data in any of twelve global regions depending on their security, compliance, data access, and availability requirements. While not only a compliance requirement, proximity to data can also help shrink the time it takes to recover in the event of a disaster.

Single Sign-On  

Druva supports SAML which allows organizations to centralized authentication for the administration of their Druva environment. This allows administrators to leverage existing centralized authentication mechanisms like Okta, Ping Identity, or Active Directory which are already being used today.  The use of Single Sign-On (SSO) helps to guarantee the availability of access to Druva and eliminates local authentication stores which cause audit and compliance headaches as well as create a security risk. To integrate Druva with your SSO authentication mechanism, see Configure single sign-on for Druva.

Testing your recovery 

As part of your data protection strategy, it is important to see if what you are backing up is actually getting backed up, whether part of a normal business continuity and disaster recovery process.

Conclusion 

While protecting data in flight and at rest are important security capabilities of any enterprise-level data protection solution, there are definitely more issues to take into account, and more capabilities to take advantage of when it comes to protecting the overall data attack surface. For identifying and implementing more such security considerations for Druva , contact Support.
