XCP-NG -> TrueNAS NFS Backup Issue

Hello, im having some issues with backups in a customer XCP-NG.

Im using XOA Comunity, and im making full backups at nights to a TrueNAS Core .

But, even if i get a successfull result, its imposible for that VM to be that size.

does someone experienced something like this?

Edit: I did experienced longer time to backup than i expected, i think its something with the truenas drives, but the backup should appear FAILED.

Updated my Freenas 11.3-U5 to Truenas 12, and after this NFS to vmware was not working like before, reverted back to 11.3-U5 now NFS works.
