Updated XOA with kernel >5.3 to support nconnect nfs option

Hi @acomav
Can you give more details on your setup and the result before/after? We might use this to update our XO guide with the new values
-
@olivierlambert Hi Olivier. I'll see what I can do. I've spent the weekend cleaning up my backups and catching up on mirror transfers. Once completed, I'll do a few custom backups at various nconnect values.

@florent hi, for the full backup test above, I used normal mode with zstd enabled. There were no snapshots of the source VM and it was stored on local ssd storage on the pool master.
can you test a backup on an empty remote with block mode ?
-
@florent Did a test on my 8.3 homelab.
Using XO on a Debian 12 VM.2 full (delta) backups using "nconnect=6" of all my 10 VM's
With block defined at remote:
without block (my normal mode):
-
I'm not sure to get it with your graph. Can you write down the average values for each scenario?
-
with block: 100-150 MB/s approx
without: 200-300 MB/sValues from observed NAS traffic.
-
@manilx Do you mean
blockas NBD mode? -
@Forza Did another test:
A: Remote as nfs share with "Store backup as multiple data blocks"
B: same but without multiple data blocks1st backup to A,"Backup"
2nd backup to B, "Backup"
3rd backup to A, "Backup"
4th backup to B, "Delta Backup"
-
@manilx This was just one VM. Did not use NBD (forgot to turn on)
-
I'm a bit confused, you are comparing block based vs VHD, but did you also change the
nconnectoption between run or kept it to a specific number? (in case, which one) -
@olivierlambert allbackups done with nfs option "nconnect=6"
-
@manilx 2 more and yes seems to be confusing and just to round it up.
Same VM as above
Delta (full) backup using NBD without and with "nconnect=6" in the remote setting:
with nconnect=6
nconnect=6 doesn't seem to do a lot.
