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

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
   

   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 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.
