How to back to the other LVM disks

Hello,

I added 4 SSD drives as LVM disk. The volume name is like "data, data1, data2 and data3". When I take "backup" on each node, I don't see these volumes. Only I can see is "local-VM". I would like to take back to one of these volumes.

Proxmox version: 8.3.1

LVM is a type of Block storage.
Local is a type of File storage (in default installation).

Backups are stored as files, so you are only able to direct backups to file storage. Additionally, you need to mark the storage pool as one that is able to accept backups:

Hi bbgeek17,

Thanks for your quick response. I tried to distroy one of LVM and created it as "directory". Now, I can take back to this directory.
Let me ask you one more question please. For guest OS like Linux, Windows, "directory (file system)" is much better than LVM? If so, I will try to clone from NAS to these directories. I created zfs (RaidZ2) with 4 SSD disks before, but the performance was really bad. So I distroyed and created LVM.
What is the best practice?

Regards,

File and block storage serve different purposes, each with its own strengths and weaknesses. Neither is inherently better than the other - rather, their suitability depends on the specific use case.

There is no universal best practice; the right choice depends on factors such as business requirements, budget, and technical expertise.

My recommendation is to experiment and determine what works best for your needs.

Cheers!
