TASK ERROR: connection error: bytes remaining on stream

[Scoffer]

Using Proxmox Backup Server for backups now. For testing I'm backing up 20-30 virtual machines two times a week. 10-15 on Monday and friday and 10-15 on wednesday and sunday. Last night I got a bit strange error on one VM. Anybody having any good ideas why?

starting new backup on datastore 'backup1': "vm/119/2020-07-12T03:30:58Z"
GET /previous: 400 Bad Request: no previous backup
created new fixed index 1 ("vm/119/2020-07-12T03:30:58Z/drive-virtio0.img.fidx")
created new fixed index 2 ("vm/119/2020-07-12T03:30:58Z/drive-virtio1.img.fidx")
add blob "/var/lib/vz/backups/vm/119/2020-07-12T03:30:58Z/qemu-server.conf.blob" (300 bytes, comp: 300)
backup failed: connection error: bytes remaining on stream
removing failed backup
TASK ERROR: connection error: bytes remaining on stream

Oh and besides that it failed, another strange thing.. Log says no previous backup but there is one

Also. Did manually back up that VM after failing and went just fine.

VM has two disks, hosts have pve-manager/6.2-9 and PBS is 0.8-6.

Any idea why this is happening?

Is this happening regularly, or was it just once? The "no previous backup" is certainly interesting as well. Do you happen to still have the PBS logs (journalctl) from when the incident occured?
