REQUEST FEATURES - iSCSI disks

[LoicTakecloud]

Hello,

I am currently migrating my hypervisors to Proxmox VE, and my LUNs in iSCSI are directly attached to my Proxmox servers.
This type of disk is “skipped” during the backup with Veeam.
Is this functionality planned for future development in Veeam’s tools?

Thanks in advance for your answers!

Hello @LoicTakecloud

Could you please provide additional details on your storage configuration?
If possible, please include the relevant config segments from /etc/pve/storage.cfg related to iSCSI and this datastore.
Additionally, could you describe the abstraction levels used for this datastore?
Are you referring to iscsi_direct or the iSCSI PVE storage type? Do you use LUNs directly, or do you have LVM over these LUNs or something else?

Hello,

I am using the LUNs directly.
Here is the requested configuration :

iscsi: MsaDC01
portal 10.248.200.1
target iqn.2015-11.com.hpe:storage.msa2060.baksz2418fc3980
content none

Hi,

That is, you are presenting iSCSI LUNs from the PVE host directly to the VMs, instead of creating virtual disk files on those LUNs.

If so, then what advantage does passing iSCSI LUNs directly to the VM give over using virtual disks? Does it give a performance boost, or is it something else?

Thank you!

very good question. the benefits of such solution are not apparent

This may not have been the intended reason, but it may be that LVM over iSCSI doesn't allow snapshots.

Could I ask for a quick clarification of the current status of this ?

The release notes for v13.0.1 (https://helpcenter.veeam.com/rn/veeam_b ... proxmox-ve) now state "VMs residing in Proxmox VE storage of any type except for the BTRFS and custom storage types."

But the v13 User guide (https://helpcenter.veeam.com/docs/vbr/u ... com&ver=13) states "Veeam Plug-in for Proxmox VE does not support backup of iSCSI disks. If iSCSI disks are attached to a VM included into a backup job, these disks will be skipped from processing."

The first statement suggests they are now supported (eg: if a disk is LVM thick over iSCSI) and the second statement suggests they are still not yet. Please could confirmation/clarity be provided?

Many thanks.

Hi,

Yes, there is some discrepancy there, indeed. Thank you for pointing that out.

Right now we do not support storages that have 'iscsi' or 'iscsidirect' type.
Devices that are passed via iSCSI directly to the guest OS are also not supported.

The documentation will be adjusted accordingly

Thank you!
