How to use multiple backup repositories pointing to a single Catalyst store


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 lack of folders concept on StoreOnce, such configuration may result in backup data corruption.


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
  3. 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
    • 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 which 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 aplpiance
    • Replace user with Admin
    • Replace password with <password for Admin user>

  4. Once the repositories are created, create Veeam backup jobs to use them normally.
