Proxmox backup server and file level restore

[Cecil]

I've been searching all day for answers and I'm so confused now.

What I want to do:

• Backup my VM's to a Synology NAS.
• Use a different Synology NAS to host my VM's (with caching and 10Gb ethernet)
• Set up two proxmox nodes in cluster to allow me to migrate VM's if one fails with the same shared network storage.
• Be able to restore the entire VM (like disaster recovery) -(I know how to do this, that part is easy)
• Be able to just restore a few accidentally deleted files in the VM (I can't figure out the requirements for this properly)

What I don't know:
Iscisi, CIFS, NFS, which one do I need to use as my shared storage for the VM hosting and backup storage to get the option to do file level restore.
Since all the storage will be network shares, can I run proxmox backup server as a VM? the iops stuff is all offloaded to the synology units after all?

Thanks for reading.

Hi there,

For your setup, it sounds like you can use either NFS or iSCSI for your shared storage. NFS is generally easier to set up and is more suitable for file-level restores, but iSCSI may offer better performance for VM hosting. Here is a previous forum post where community members were discussing the benefits of both solutions: https://forum.proxmox.com/threads/iscsi-zfs-or-iscsi-proxmox-storage.83219/#post-366192

As for the Proxmox backup server, it can definitely be run as a VM on top of your shared storage. The performance of the backup server will depend on the performance of the Synology units and the network connectivity between them.

It's also worth noting that Proxmox itself offers backup and restore options for both entire VMs and individual files within a VM. You can read more about this in the Proxmox documentation: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#vzdump_restore

Hope this helps!

Thanks for the response, I read both those links before. The second one says :

16.9.3. Single File Restore​

The File Restore button in the Backups tab of the storage GUI can be used to open a file browser directly on the data contained in a backup. This feature is only available for backups on a Proxmox Backup Server.

At the moment with my current setup that I'm looking to replace the option is certainly not there. Right now I have lvm-thin on a hw raid controller.

I also scanned through the iscisi vs nfs thread, not sure by how much iscisi wins. I feel like I might just stick with NFS for simplicity's sake.

Lastly CIFS or NFS, I found this: https://www.geeksforgeeks.org/difference-between-nfs-and-cifs/
Judging from that I should use NFS since both the synology NAS and proxmox are Linux systems - is that right?
