Challenge

To minimize backup job duration and reduce disk space used for backups, you can configure multiple Veeam Backup & Replication repositories on a single HPE StoreOnce Catalyst Store. However, due to the lack of folders concept on StoreOnce, such configuration may result in Veeam B&R metadata inconsistency, causing backup data corruption.

Solution

To create multiple Veeam Backup & Replication repositories on a single HPE StoreOnce Catalyst Store and avoid backup data corruption, do the following:

  1. Create a new HPE StoreOnce Catalyst Store.
  2. Make sure the Veeam PowerShell Module is loaded by running  the following command:
Add-PSSnapin -Name VeeamPSSnapIn -ErrorAction SilentlyContinue
 
Starting from v11 the command should be:
Get-Module -Name Veeam.Backup.PowerShell
  1. Use the following cmdlet to create repositories. Run the script multiple times to create multiple repositories.

Add-VBRBackupRepository -Name HPE-StoreOnce-01 -Folder storeonce://storeonce_fqdn:objectstore_name@/subfolder_name -Type HPStoreOnceIntegration -StoreOnceServerName storeonce_fqdn -UserName user -Password password

NOTE:
  • The format above is for stores over IP (Catalyst over Ethernet).
  • For FC-connected stores (Catalyst over Fiber Channel), replace the StoreOnce name with the "COFC" identifier for FC.
  • When using FC, you may also need to add "-Server <gateway>" before the user switch, where gateway is the Gateway server that has FC access to the storage.
  • Replace HPE-StoreOnce-01 with the selected name of the Veeam backup repository
  • Replace storeonce://storeonce_fqdn with the short name and FQDN of the StoreOnce appliance
  • Replace objectstore_name with StoreOnce Catalyst store name
  • Replace subfolder_name with the subfolder name. The subfolder name must differ for each repository.
  • Replace storeonce_fqdn with the FQDN of the StoreOnce appliance
  • Replace user with Admin
  • Replace password with <password for Admin user>
  1. Once the repositories are created, create Veeam backup jobs to use them normally.
