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

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 lack of folders concept on StoreOnce, such configuration may result in 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
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
   
   Notes:
   
   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.
   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.
