LXC Slow Backup with Suspend

[liberodark]

Hello,

I know that this subject may be drowned among others given the number of posts on this subject.
But this is clearly a problem.
Currently I am in POC on Proxmox and the backups are horribly slow.
So here is my configuration:

PVE 6.4-6
CPU i7 7700
256 GB SSD
16 Ram
2 x 1Gb Ethernet

The node is connected in NFS v3 on netapp on a dedicated network card.
So it is impossible to save in suspend mode whether it is with PBS or not it is slow very very slow.
Quick little comparison:

With an LVM-Thin node (Snapshot)

VMID	NAME	STATUS	TIME	SIZE	FILENAME

TOTAL​	00:06:59	4.42GB

With an NFS node (Suspend)

VMID	NAME	STATUS	TIME	SIZE	FILENAME
107	xxxx	OK	00:17:13	4.32GB​	/mnt/pve/netapp/dump/vzdump-lxc-107-2021_05_20-10_40_39.tar.zst
TOTAL​	00:17:13	4.32GB

With an NFS node (Stop)

VMID	NAME	STATUS	TIME	SIZE	FILENAME
107	xxxx	OK	00:01:41	4.32GB​	/mnt/pve/netapp/dump/vzdump-lxc-107-2021_05_20-10_13_24.tar.zst
TOTAL​	00:01:41	4.32GB

My vzdump configuration :

# vzdump default settings

tmpdir: /var/tmp/
#dumpdir: DIR
#storage: STORAGE_ID
#mode: snapshot|suspend|stop
#bwlimit: KBPS
#ionice: PRI
#lockwait: MINUTES
#stopwait: MINUTES
#size: MB
#stdexcludes: BOOLEAN
#mailto: ADDRESSLIST
#maxfiles: N
#script: FILENAME
#exclude-path: PATHLIST
#pigz: N

My concern is how to reduce this time to something acceptable?
If this is not possible I should therefore do without proxmox.
Knowing that I must use shared storage.

Best regards

Are you aware that you are NOT using Proxmox Backup Server here?

Your results just show the (old) vzdump.

Hi,

Sorry I forgot to publish the results of PBS here are recent ones.
Currently I am thinking about the subject of backups.
Because I use netbackup for all backups.
So there would be three solutions :
vprotect + netbackup
netbackup only
pbs only

PBS version 1.1-5

Here are the results with PBS :

With an PBS (Suspend)

VMID	NAME	STATUS	TIME	SIZE	FILENAME
107	xxxx	OK	00:32:31	448.89GB​	ct/107/2021-05-20T11:18:06Z
TOTAL​	00:32:31	448.89GB

With an PBS (Stop)

VMID	NAME	STATUS	TIME	SIZE	FILENAME
107	xxxx	OK	00:18:05	448.89GB​	ct/107/2021-05-20T10:48:30Z
TOTAL​	00:18:05	448.89GB

Best Regards

PS :
The CT 107 does not exceed 5GB. I don't know why it writes 448.89GB. But hey, that's a detail.
