Hello,

I'm running proxmox 4.1 and I'm experiencing since the beginning of the setup of this system an issue every night during the backups.

Randomly but every day, some backups fail, i have only 3VM and I'm backupping to a remote NFS.

Here the last day:
INFO: starting new backup job: vzdump 102 --mailto 'mail@mail...' --compress lzo --storage dataset1_proxmoxbackup1 --mode snapshot --quiet 1 --mailnotification always

I have free space:
192.168.0.75:/dataset1_proxmoxbackup1 7.3T 4.1T 3.3T 56% /mnt/pve/dataset1_proxmoxbackup1

No logs error found. The NFS / network connectivity is local and good. I tried to divide in multiple job, delete/create jobs, change start date, nothing, randomly some job fail with that error...

Any hint?

Thanks
