Hello!
I have a Synology NAS that I'm trying to use as a StarWind VTL.
I'm currently accessing it via CIFS.
I was wondering if we can use StarWind VTL over CIFS or SMB?
If I can't use CIFS, what's the best way to convert the NAS to iSCSI?
Thanks

Thanks, I was able to get the NAS connected via iSCSI.
My next issue is the slowness when doing the Cloud Replication.
From what I see the back ups goes like this:
VEEAM -> VTL Device -> Routes back to VEEAM backup server -> Backblaze B2.
The bottleneck I'm seeing is the traffic from the VTL device to the VEEAM backup server.
Is there anyway to speed it up?

What nominal connection speed do you have between the VTL device and the VEEAM backup server?
What is the real transfer result you get?
Have you tried testing networking performance with no VTL related data transfer, e.g. using the iPerf utility?

Everything is connected via a Gigabit backbone.
I tried doing a single 2 GB file transfer between the VTL device and VEEAM backup server and it took 20 seconds @ 113 MB/s.
I just timed it with the Backblaze B2 cloud replication, it took roughly 42 minutes to upload a 28 GB tape file to B2.
Other cloud backups are getting much faster speeds.
Am I doing something wrong to get the slow transfer speeds?
