Fujitsu ETERNUS CS800

You can use Fujitsu ETERNUS CS800 deduplicating storage appliances as backup repositories.

Fujitsu ETERNUS CS800 Deduplication

Fujitsu ETERNUS CS800 appliances use Fujitsu ETERNUS CS800 data deduplication technology. During backup data transfer, Fujitsu analyses blocks in a data stream. Instead of copying redundant data blocks Fujitsu uses reference pointers to existing blocks on the storage device.

Backup Infrastructure

To communicate with the Fujitsu appliance, Veeam Backup & Replication uses two Veeam Data Movers that are responsible for data processing and transfer:

  • Veeam Data Mover on the VMware backup proxy
  • Veeam Data Mover on the Fujitsu appliance

Fujitsu does not host the Veeam Data Mover permanently. When any task addresses a Fujitsu storage, Veeam Backup & Replication deploys and starts Veeam Data Mover on the Fujitsu system.

Veeam Data Mover establishes a connection with Veeam Data Mover on the VMware backup proxy, enabling efficient data transfer over LAN or WAN.

Note

Since Veeam Backup & Replication version 12, deduplicating storage appliances use the TLS connection. You can disable the TLS connection with a registry value for the deduplicating storage appliances that do not support the TLS connection. For more information, see this Veeam KB article.

Backup Repository Configuration

Configure Fujitsu backup repositories in the following way:

  1. Create at least one share on each Fujitsu appliance. Enable VDMS (Veeam Data Mover Service) for the created share. Leave default compression and deduplication settings for the share.

Note

When adding credentials for Fujitsu, use only lower case symbols for the user name.

  1. Configure Fujitsu backup repositories and point them at the created shares on each Fujitsu appliance. Set the Limit maximum concurrent tasks to N option to 10 tasks. This limit can be tuned up or down with assistance from Fujitsu Customer Support.

When you add Fujitsu servers to the Veeam backup infrastructure, make sure that you use the UPN format for an Active Directory account user name (for example, john.doe@domain.local), and enter the user name in lowercase letters only.

Backup Job Configuration

For the backup jobs, use the forward incremental backup method. We recommend that you enable synthetic full and schedule them to run on a weekly basis. Also, enable active full backups and schedule them to run on a monthly basis. For more information, see Backup Settings. We recommend that you do not enable encryption for the jobs targeted at the deduplication storage appliance. Encryption has a negative effect on the deduplication ratio. For more information, see Data Encryption.
