Slow transfer speed due to SSD cache acceleration

[mman3222]

Lets say I have file "123.mkv" in NVMeDrive\Movies. Will it copy to my regular store or MOVE/cut it to regular storage? When Syncback runs at night, it moves the files so then my cache drive is 100% empty again.

Ah, okay. It's not really synchronizations, it's moving data.

HBS can't do moves, only backups and syncs. That's very easy to work around though as piggy-backed to the sync job you could have a job that sync an empty folder to the SSD folder and thereby delete all data on it. In addition, that would be a completely safe transfer of the data. I don't know if Syncback actually do a sync plus delete behind the scenes or if it really use the more risky approach of moving? If the latter, that would be another disadvantage with Syncback.

If you're not familiar with HBS, how do you backup the data on the NAS? Do you use Synback for that as well?

It's just easier for me to stick with Syncback then. I only have 0 - 600GB MAX in a night it needs to move. However, the average is probably 50 - 100GB.

I use Google Drive with Stablebit to backup my data. And you're correct. I use Syncback for that too. Once a day it backs up. Stablebit tricks Google Drive to making it a "local" hard drive on my computer. It's encrypted, and Syncback backs all my stuff up flawlessly. I've been using this method for around 2 years now.

HBS can backup to Google drive as well, including doing client-side encryption, but if what you have work and you're happy with it I understand that you don't want to change as HBS will no doubt require some learning time.

I just wanted to inform that a good NAS-integrated backup/sync solution existed for those that wasn't aware. I do agree that Syncback is a nice Windows backup software.

FWIW, I have had numerous issues with HBS as it does not play nicely with S3-compatible storage. So I use Arq backup on a Mac to backup my NAS.

So today I checked my W/R speeds and was very surprised.
This 872XT system has been up for 12 days. I have not flushed the cache since.
See images for surprising speeds - 1202MB/s Write 1862MB/s Read
Repeatable over several tests +/- 100 MB/s.
Most system specs in signature, using Mellanox MCX313A single port 40GB/s card on host pc but still MCX314A dual port 40GB/s card on NAS.
I use the second NAS 40GB/s port with adapters to provide 10Gbe on 10-BaseT.

I also confirmed by transfer multiple 30GB movie files at 1.3GB/s to 1.9GB/s with Windows file copy.

I have no idea what, but for months I have been lucky to see 700MB/s W/R and sometimes as low as 500 or even 400 MB/s.

I'll keep track over the coming days and hope it's sustained. I am up to date on QTS 4.4.3.1421.

Those speeds are normal for me with my TS-672XT. I have a Samsung 1TB M.2 970 EVO SSD that I use for cache and I get 1.15GB/sec over a mixture of cat 5e / cat 6 cables.

I'm surprised you were getting such slow speeds prior to this.
