Lost data after backup restore

I was running container in Proxmox. There was one volume excluded from backup (on dpool).
After restore from backup (to rpool) Proxmox removed volume on dpool and created empty on rpool.
I have lost my data...
Help! How can I restore that zfs dataset for that volume?

Can I use

zpool import -o readonly=on -D -f -T <LAST-GOOD-TXG> poolName

if last pool operation was 'destroy'?

If the last operation was zfs destroy, then your data are gone.

Now I know it...

But I still does not understand why Proxmox destroyed CT disk that was not contained in backup.
When making backup I checked only one disk for backup. After restore such backup Proxmox destroyed two disks: one, which has backup copy and other, that does not.
May be it will be better just to rename such disk and allow user to make cleanup later?
an-inplace restore overwrites the existing container. the GUI even tells you so and let's you confirm before proceeding..
