I have a similar (and inferior) arrangement to RobJ and bubbaQ but with Crashplan. I set up a back-up share which is private and not published and set Crashplan to back up there every 3 days. Basically my rationale is if I get a ransomware attack, I should be able to detect it within that period and switch off Crashplan.

Question 1: What would unRAID do if you write to a file that is already on the array? Does it write straight to the array or does it make a copy in cache first? Question 2: What if the cache is full? As far as I know, if cache is full, unRAID will write straight to array - negating any defense. Perhaps a "plug-in-able" thing to do is to have Cache-only shares linked to Array-only shares and have the plugin does the moving (since as far as I know, plugins have full access to all shares). The complication is how to see all the content in Cache + Array. Or things would be a lot easier done at LT code level. Perhaps have a "protected" flag for shares which turn cache on and disable writing if cache is full + "copy-on-write" kind of flag. The complication is with how to deal with free space and stuff. Nothing is easy. *sigh*

Awesome idea! I think right now, unRAID can be made resistant to Ransomeware attack but it would be a quite round-about way (e.g. having an isolated "high risk" VM with only some share accessible). The above would make it even better.

It only has 1 resolution. I can't increase it.

My VNC-based VM (which as I understand it uses a virtual GPU of sort) seems to be stuck at a fixed resolution i.e. tiny screen. Is there anyway to increase the resolution? I don't know maybe adding some RAM as graphic memory or something. I'm certainly not asking for 4k, but 720p would be really nice. *Edit: I did check in the VM display properties and it only has 1 resolution. I can't increase it. Hence this question.

OMG I got it to work!!!!!! And it looks like Windows actually detected it as a Bluray writer too (put a blank Bluray in and it asks if I want to use it like a USB )!!!!! I put this in the xml right before the </devices> tag: Note the index = 1 and controller = 1 amendment. <controller type='scsi' index='1' model='virtio-scsi'/> <hostdev mode='subsystem' type='scsi'> <source> <adapter name='scsi_host9'/> <address type='scsi' bus='0' target='0' unit='0'/> </source> <readonly/> <address type='drive' controller='1' bus='0' target='0' unit='0'/> </hostdev> The start the VM (which crashes but it crashes randomly due to lack of memory - oh well, running it in VMWare Workstation) and then install virtio scsi driver (which shows up as passthrough) for the 2nd no-driver scsi item - which windows just install the drivers on the virtio disk, no need to force it. Then voila! When I checked the xml again, unRAID has automatically rearranged the codes and changed it a little: <controller type='scsi' index='1' model='virtio-scsi'> <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/> </controller> ... <hostdev mode='subsystem' type='scsi' managed='no'> <source> <adapter name='scsi_host9'/> <address bus='0' target='0' unit='0'/> </source> <readonly/> <address type='drive' controller='1' bus='0' target='0' unit='0'/> </hostdev> *there should be an emoji for celebration*

Windows says the scsi driver on the virtio disk is not designed for my drive. I tried to install it regardless and the errored scsi device went away but no drive.

I tried. It doesn't work. :'( VM starts fine (and I doubled check the hostdev section is in the xml) but nothing shows up in Windows. :'(

Unfortunately my X99 Sabertooth has the same issue (all the buses on the same controller) even after BIOS update :'( lsusb Bus Device ID Device Name Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub 003 00:14.0 USB controller: Intel Corporation C610/X99 series chipset USB xHCI Host Controller (rev 05) Bus 003 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) 003 00:14.0 USB controller: Intel Corporation C610/X99 series chipset USB xHCI Host Controller (rev 05) Bus 003 Device 003: ID 05e3:0608 Genesys Logic, Inc.

I read some confusion information on the forum: There's a thread which says unRAID does not have optical drive drivers and thus will never support passing through There's another thread which says it's possible using "by-id" (which I can see on my rig e.g lrwxrwxrwx 1 root root 9 Apr 22 21:40 ata-PIONEER_BD-RW_BDR-207D -> ../../sr0) but then it refers to XEN, not KVM, I think. Someone also said the only way is to passthrough optical drive is the entire sata controller. Confused.com

On the front post, I noticed this: It only refers to Linux. Will I run into problems if I use NTFS with Windows VM?
