HPE StoreOnce and hardened repository

[Il Ventu]

Hello, at the moment we have, for backup copy job, a StoreOnce appliance configured with Catalyst protocol, the storage gateway is a physical Windows machine.
At the moment Veeam v11 doesn’t support natively the immutability feature, unfortunately we need to implement this asap.
The idea is to reconfigure the physical Windows machine wiping all and install RHEL 8.5, also wipe StoreOnce and reconfigure it.
Unfortunately I have no idea how to use the space on StoreOnce to configure a XFS partition to be used in RHEL.
Is this possible or sadly we have to wait Veeam v12 ?

Not possible for the StoreOnce (yet, coming in V12). Do you have another backup target besides the StoreOnce you could use as a immutable repo?
Otherwise you can also use a S3 repository which supports immutability.

Hello, thank you for the answer.
So you are saying that, at the end, we can use the storage space on a StoreOnce device only using Catalyst protocol ?
There's no way to use the StoreOnce with Linux in any way ?
Regards.

The StoreOnce doesn't offer any block services, so there's no way to publish it's storage as a volume/LUN to a different server.
You'll either have to use the Catalyst Protocol via IP/FC or via a file share.

So for immutability you will have to wait for some months till v12 gets released.
Until then go with S3 or repurpose some other hardware for the hardened Linux repository.

There's any valid release date for V12 ?
End of 2022 ? Beginning of 2023 (Jan? )

No fixed date but the plan is to have RTM in January.
