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
Note: Once StoreOnce Repositories based on subfolders of a Catalyst Store have been created, a StoreOnce Repository using the parent Catalyst Store itself without a subfolder cannot be used and should be removed if it exists.
To create multiple StoreOnce Repositories using a single HPE StoreOnce Catalyst Store, and avoid backup data corruption, do the following:
- Create a new HPE StoreOnce Catalyst Store.
- Open an Administrative PowerShell on the Veeam Backup Server, and use the following cmdlet to create repositories:
- Modify the parameters shown in <> to the correct values without the <>. (See syntax notes below)
- Remember, to change <repository_name> and <subfolder_name> values when attempting to create multiple repositories.
Add-VBRBackupRepository -Name <repository_name> -Folder storeonce://<storeonce_fqdn>:<objectstore_name>@/<subfolder_name> -Type HPStoreOnceIntegration -StoreOnceServerName <storeonce_fqdn> -UserName <user> -Password <password>PowerShell Syntax Notes
- The format used in the example 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.
- Script Values that must be adjust prior to excution:
- <repository_name> — the desired name of the backup repository
- <storeonce>://<storeonce_fqdn> — the short name and FQDN of the StoreOnce appliance
- <objectstore_name> — the StoreOnce Catalyst store name
- <subfolder_name> — desired subfolder name.
The subfolder name must differ for each repository. - <storeonce_fqdn> — the FQDN of the StoreOnce appliance
- <user> — Admin
- <password> — Admin user password
- After creating the desired repositories, they may be used as the target for Veeam backup jobs.
