Proxmox and Oracle 11g

[roster79]

Hello!
I've got
-Proxmox VE v.5.1
-Storage filesystem XFS
-Virtual machine disktype -raw, OS - Oracle Linux 7.5, Oracle 11g, database size - 200+G,
database filesystem - LVM+XFS
All works fast!

BUT I can't normally restore backup(snapshot) of virtual machine. Where is no errors in restore process, but database can't start. Where is no sync in datafiles. File system01.df if older than controlfiles. It wants backup of database.
what cat I do to get worable snapshot of work system?
I think, Error in filesystem of proxmox virtual machine storage or disktype of vm disks.
Help me please.
Thank you for lost time.

Only to understand you correctly:

You have your VM on LVM with LVM snapshots?

What about an oracle rman backup?

proxmox storage on simple LVM partition (lvcreate -n virt1 -l +nGB vg00; mkfs.xfs /dev/vg00/virt1; mount /dev/mapper/vg00-virt1 /mnt/storage); in virtual machine same method.

It's work, but ... It's simpler to restore backup of virtual machine for developers.
