vStor Partnerships

The vStor Partnerships feature lets you connect two vStor instances to facilitate the transfer and synchronization of snapshots. Once a partnership is established, you can configure a replication relationship or an offload relationship between a source volume on one partner and a target volume on the other. Volume replication is crucial for efficient data management, ensuring data redundancy and continuity across different storage environments, while offloading helps reduce primary storage usage while preserving access to historical data.

Partnerships are established at the vStor user level, meaning there can be several partnerships between any two vStor instances, provided that any user on vStor A is in partnership with no more than one user on vStor B. Partnerships are symmetrical, allowing volumes from vStor A to replicate or offload to vStor B and vice versa.

User-level partnerships enhance the possibilities resulting from vStor user roles. For example, each standard user can have different pool permissions and therefore be able to replicate only volumes from permitted pools.

  2. Enter the address of your remote partner vStor and the credentials of the user you want to establish the partnership with.

  1. Click Save. Or go to Advanced Options (see below).

Advanced Options​

The Advanced Options section allows you to configure an alternate IP address for the partner to communicate with the local vStor. You can also specify alternate ports for SSH communication.

Replication deletion protection requires MFA to be enabled on the source vStor system. There is no MFA check on the replication target. For details, see Using Multifactor Authentication (MFA).

Managing Partnerships using vStor CLI​

Creating a Partnership​

To create a new partnership using vStor CLI, use the following command, specifying the address, username, and password of the remote server:

vstor partner add --remote_addr <remote_server> --remote_user <remote_username> --remote_pass <remote_password>
Tip.

To edit an existing partnership, use the add command again.

For more commands and parameters, use the --help flag at any level, e.g:

vstor partner --help
vstor partner add --help
