Anyone can help-me?

I am using Proxmox 5.3-5, with a NFS backup storage witch Gigabit conection.

I made backup of my virtual machines with Fast Compression (LZO). But when i was restore have error and the process failure. Just if i use LZO compression, if i don´t use any compress method works fine.

This is the output error (I have this problem on two diferents machines in diferents sites):

Hi Cris. Yes.
This is a new proxmox instalation, in a new Dell Server with 64Gb RAM. I have another client with a old good server with this same problem.
And, i am restoring in Third server, just to test, the result is same.

Funny is, just witch compressed, if i don´t compress the backup, works well.

Can be a Lzo Package?

I will update one of this proxmox servers to 5.4 to test backup again.
Some thoughts for narrowing down the issue: Are you sure that the backup itself is okay? Can you reproduce this only with this or also with other compressed backup archives? What about gzip compression?
I don´t tried with gzip compression, just LZO.
I made this test with 3 VM´s, but just with this version of proxmox 5.3-5.
I will trie with 5.4.
