nested / tree snapshots with proxmox?

[hkais]

Hi out there!

I am wondering what I did wrong that I cannot create tree-snapshots / nested snapshots with proxmox?
Means something like

-+-aSnapshot01
 |   |
 |   +-aSnapshot01-subSnap01
 |   |   |
 |   |   +-aSnapshot01-subSnap01-subSubSnap01
 |   |   |
 |   |   +-aSnapshot01-subSnap01-subSubSnap01
 |   |
 |   |
 |   +-aSnapshot01-subSnap02
 |
 +- aSnapshot02

I am coming from vmware vshpere / esxi and there I could use this feature back the last 10y. So wondering if this feature is simply missing or if I did something wrong?

Tree snapshots, if i'm right about what you are using are something similar when you have a regular lvm-thin storage, so you take snapshots,and you can revert to any of them. In zfs you can only go back to the last one.

Proxmox has full support for nested snapshots if the storage also supports it (for example the default lvm-thin storage).

Your tree-like snapshots are also possible with QCOW2 and I use them for test machines regularly.

thanks for the answers, so the backend storage has to support it.

Let me try to summarize:

ZFS
can only linear going back in one path, no nesting?
In my above example only
aSnapshot01 > aSnapshot01-subSnap01 > aSnapshot01-subSnap01-subSubSnap01
or
aSnapshot01 > aSnapshot01-subSnap02
or
aSnapshot02
is possible

LVM
can only linear going back in one path, no nesting?

LVM-thin
shall be able to handle the nested tree snapshots?

ceph?
