Overview

A server group is a logical categorization of the servers that share something in common. For example, servers located in one region can belong to one server group. Similarly, servers having the same operating system can belong to another server group.

While creating a server group, you must associate it with a storage, and attach a single or multiple backup policies to the server group. Backup policies define the backup content, and the backup schedule.

Assigning a server to a server group eliminates the need for configuring backup policies for individual servers, thus simplifying server management.

Note: To request a storage for a new location, contact the Druva Support team (support@druva.com).
In a production environment, we recommend that you create separate server groups for the servers that are geographically co-located.

Best practices for creating server groups

To account for the difference in the SQL server and File server architecture, Phoenix requires creation of separate backup policies for File servers and SQL servers. Phoenix allows you to assign both File server and MS- SQL server policies to one server group. 

In a production environment, we recommend that you create one or more server groups for your file servers, depending on the backup needs of the servers. For example, if your File server databases does not change frequently, you can create a server group and assign to the group a backup policy that includes a weekly backup for longer durations. For File servers having high volumes of data activity, you can create a server group, and assign to this group a backup policy that includes backups every second day.

We recommend that the server groups that you create includes the File servers that are geographically co-located and belonging to the same platform. We also recommend that you assign server groups to storage that are geographically the closest. This ensures faster backups and restores while reducing the demand on your organization's bandwidth. Similarly, to simplify data backup management across server groups, we recommend that you create separate server groups for each platform (Windows and Linux). 

Note: In a production environment, we recommend that you create a server group each for the servers that are geographically co-located, and belonging to the same platform. 

Example server group

As an example, consider two remote offices, A and B, both having 5 SQL servers and file servers each. The file servers in the remote office location A see large volumes of data flow. Most of the data changes are new additions. The remote office A is located in Seattle. The file servers in the remote office location B also change frequently. However, the changes are minor and are generally updates. The remote office B is located in New York. For the file servers of the remote location A, you can consider creating a server group, and attaching to it a backup policy that includes bi-weekly backups for longer duration, along with daily short-burst backups. At the time of creating this server group, you can assign to this group a storage that is geographically closest to Seattle. Similarly, for file servers at remote location B, you can create a server group, and assign to this server group a backup policy that includes a weekly backup for longer duration, along with short-burst backups every second day. 

Note: This is just an example scenario. The exact server group and backup policy configuration for your setup depend on your file server data needs and your organization's policies. However, you can request for backup policy recommendations by writing to the Druva Support team (support@druva.com).

    Backup & Restore

    The Backup & Restore section displays backup and Restore jobs for the last 7 days with the following three status: 

    • Successful
    • Successful with errors (Backup only)
    • Failed 

     For detailed explanation of each parameter, see Dashboards.

    Bandwidth Usage The Bandwidth Usage section displays the average bandwidth consumed over the last one week. 

    Configuration

    The Configuration section displays the following:

    • Storage: The storage used by the server group.
    • CloudCache: The Cloud Cache associated with the server group.
    • MS-SQL server Backup Policy: The name of the MS-SQL server backup policy used.
    • File server Backup Policy: The name of the File server backup policy used.
    • VMware Backup Policy: The name of the VMware backup policy used.
    • Retention Policy: The name of the retention policy used.

    Backup Data

    The Backup Data area illustrates the following data for the last 90 days:

    • Source+Change:The amount of backup data generated at source. This includes the initial full backup and incremental data from all subsequent backups.
    • Current Source: The size of the data on the source server(s) at the time of the last backup.

Add a server group

  1. Log on to Phoenix Management Console. 
  2. On the menu bar, click All Organizations, and select the required organization from the drop-down list.
  3. On the menu bar, click Manage > Server Groups
  4. Click Add New Server Group
  5. On the Add Server Group page, enter or select appropriate values in the following fields:
    Field Description
    Server Group Name The name of the server group.

    Storage

    The storage that you want to associate with the server group.

    Note: You cannot change the storage later. 

    Backup Policy Type

    The type of the backup policy that you want to assign to this server group.

    Phoenix provides the following options to assign backup policies to the server group.

    • File/MS-SQL
    • VMware

    Click File to apply File server backup policies to the server group.

    Note: If you attach a server to a server group, which does not have a policy type same as the previous server group, the restore points are deleted corresponding to the unmatched policy type. For example, if a server attached to a server group with File server and MS-SQL server backup policies, is reconfigured to a server group having only File server backup policy, then the restore points corresponding to the MS-SQL server backup policy type gets deleted.

    Backup Policy

    The backup policy that you want to assign to this server group.

    To assign a File server backup policy to the server group,

    • Under Backup Policy, select the File Server check box, and select the required policy from the corresponding drop-down list.

    Note: If your server runs mixed workloads of File server and MS-SQL server, you can assign File server and MS-SQL server backup policies to the server group. To assign a MS-SQL server backup policy to the server group, select the MS-SQL​ ​​​​Server check box, and select the required policy from the corresponding drop-down list.

    Retention Policy

    The retention policy that you want to assign to this server group.

    For more information, see Add Retention Policy.

Update server group details 

To change the backup policy or the retention policy of a server group, you can modify the server group. When you change the backup policy of a server group, the old backup policy rules are no longer valid. Instead, Phoenix backs up the data according to the rules defined in the new backup policy.

Note: After you assign a new backup policy, the first backup from your servers is a full backup. However, Phoenix saves a copy of the backup data that was created following the previous backup policy.

Similarly, when you change the retention policy of a server group, the retention rules of the new policy are applicable for all servers belonging to the server group. 

Note: You cannot update the server group to include a different type of server. For example, if you created a server group for file servers, you cannot update this server group to include SQL servers or virtual machines.

Procedure

  1. Log on to Phoenix Management Console. 
  2. On the menu bar, click All Organizations, and select the required organization from the drop-down list.
  3. On the menu bar, click Manage > Server Groups
  4. On the Manage Server Groups page, click the server group that you want to update.
  5. Under the server group details page, click Edit.
