Veeam Backup & Replication supports ECS using the S3 REST API.

The following sections review best practices for configuring a single Veeam scale-out repository with a performance tier (local storage) and a capacity tier (ECS object store).

Veeam Backup & Replication communicates with the ECS platform through a network connection. Use the ports listed in the following table if connecting directly, or resolve to these ports if using an IP load balancer.

Table 1.      ECS data access ports

ECS Connection Manager was used to perform IP load balancing for the examples discussed in this document and for validation runs in the Veeam Ready Program.

The management UI and management API are used by browsers and tools independent of Veeam Backup & Replication.

The administrator must first create an account on the ECS system and obtain a secret key for the account. In addition, the administrator must create an ECS S3 bucket that will be the target for backup sets.

Administrators who want to use S3 Object Lock retention functionality must create an Identity Access Management (IAM) type of account and enable Object Lock capability on the created bucket.

If S3 Object Lock is not required, the administrator can use either an IAM style account or a traditional ECS account to authenticate to the ECS system. Object Lock does not have to be enabled on a bucket if setting object retention is not required.

After installing Veeam Backup & Replication, the administrator can do the following with Veeam v12 and earlier.

1. Create a Veeam backup repository for the performance tier (local disk on server)
2. Create a Veeam backup repository for the capacity tier (object repository on Dell ECS)
3. Create a Veeam scale-out repository, which uses the performance tier then the capacity tier on which to store backup jobs.
4. Define a backup source (This document describes backing up VMs from a vSphere system, but any or all supported backup sources could be defined.)

With Veeam Backup and replication v12:

1. Create a Veeam object repository for the Dell ECS.
2. Define a backup source (This document describes backing up VMs from a vSphere system, but any supported backup sources could be defined.)

After configuring Backup & Replication, the administrator can define backup jobs that back up to the scale-out repository.
