Sadly...that isn't working. I attached my VM XML.

I do have both the qemu guest agent and the spice-vdagent installed.

The only difference I can spot is that you seem to have two VirtIO Serial drivers? I only have one.

At a loss here, not sure what else it could be. Does it matter exactly where the above snippet is added to the XML?

Also, off topic but related, have you figured out how to save the remote viewer recent connections? That seems to be broken. I saw some off site posts that seem to indicate it may be a known issue.

I know you can call the .exe from CLI and pass the URL to start, but that's a bit clunky when the app has a recent list available. (maybe)

Sorry for going off topic! Continued over here-->

Please note.

This thread is for Announcing the newest release and mentioning any issues you might have. Please make another post in General requiring any technical support and link to it.

This is one of the only times we are asking you to cross post.

By doing this it reduces the amount of clutter that might happen and direct others that might have the same problem to the discussion.

I’ve stepped back from the forum in recent times but felt compelled to login and respond.

(Un)Raid is not for backup, it’s for for availability. If you are sensitive to “Loss” of data you should take appropriate steps to back it up based on your risk appetite for the unexpected.

Guys like you are the literal bane of everyone's existence. Unraid is not for backup??? So I can have a disk that allows redundancy or even 2 and that's not a backup solution??? This is why the common man has most of their data on a portable hard drive with no protection on failure. Because people like you make impossible solutions. So what I am supposed to buy 2 or 3 or 4 NASes for backup across multiple continents? How about we start talking about the practical matters for a second? This unpaid solution IS a backup solution for many - and Unraid as a company should be ashamed of shameful bugs - the stakes are high in this business.

I feel like this is why I never recommend unraid to a friend. The complexity, the issues. I recommend Synology instead.

No it is definitely not a backup solution. This is true whether using Unraid or any other system with parity or mirrors or whatever.

A very simple example should make this perfectly clear. Suppose you delete a file by accident. How is parity going to help you recover that file?

With a backup, you just get the file from your backup.

What if someone, intentionally or accidentally, formats a disk? Lots of other examples that parity can't help you recover from, and mirror won't help you recover from either, since parity or mirror just lets you get the latest contents, whether it is missing an accidentally deleted file, or if the whole disk was formatted.

You must always have another copy of anything important and irreplaceable. Parity is NEVER a substitute for backup, whether Unraid or some other more traditional RAID system.

No it is definitely not a backup solution. This is true whether using Unraid or any other system with parity or mirrors or whatever.

A very simple example should make this perfectly clear. Suppose you delete a file by accident. How is parity going to help you recover that file?

With a backup, you just get the file from your backup.

What if someone, intentionally or accidentally, formats a disk? Lots of other examples that parity can't help you recover from, and mirror won't help you recover from either, since parity or mirror just lets you get the latest contents, whether it is missing an accidentally deleted file, or if the whole disk was formatted.

You must always have another copy of anything important and irreplaceable. Parity is NEVER a substitute for backup, whether Unraid or some other more traditional RAID system.

But why I would intentionally or accidentally delete a file. That's such a deliberate action. Why would I accidentally format a disk? Again it's an extremely deliberate action.

Accidents do happen. You think nobody has ever accidentally deleted a file? Or perhaps overwrote a file and wished they could get the original file back?

Nobody that knows anything relies on parity or mirrors as a backup solution, whether Unraid or some other implementation of RAID.

Guys like you are the literal bane of everyone's existence. Unraid is not for backup??? So I can have a disk that allows redundancy or even 2 and that's not a backup solution??? This is why the common man has most of their data on a portable hard drive with no protection on failure. Because people like you make impossible solutions. So what I am supposed to buy 2 or 3 or 4 NASes for backup across multiple continents? How about we start talking about the practical matters for a second? This unpaid solution IS a backup solution for many - and Unraid as a company should be ashamed of shameful bugs - the stakes are high in this business.

I feel like this is why I never recommend unraid to a friend. The complexity, the issues. I recommend Synology instead.

What happens if the server is a victim of a lightening strike?

What happens if the server is stolen?

What happens is your house/business catches fire and is a total loss?

What happens if the server is 'drowned' due a flood or pipe breakage?

There are a lot ways to end up with a catastrophic loss of data that no parity system can prevent!!!

But why would he intentionally or accidentally strike his server with lightening?

Why would he intentionally or accidentally have his server stolen?

Why would he intentionally or accidentally set his house on fire?

Why would he intentionally or accidentally submerge his house with water?

My wife unintentionally deleted a whole year's worth of photos from my server. She has no idea how it happened because she did not intend to do it. Since I keep three backups of all the important data on unRAID (external USB drives, second unRAID server with weekly backup, in the cloud), restoring that folder for a whole year of photos was pretty easy. There is no way parity was going to save me (her) from that.

Now that I know better, I have told my wife to never accidentally or intentionally delete something again because that has to be a deliberate action even if she claims she does not know how she did it!

Because the house was on fire after being struck by lightning?

Several years ago, my wife got a new laptop. Before she gave the old one away to a friend, she deleted her chrome bookmarks from it. Of course, that propagated throughout chrome on her other devices and so she no longer had chrome bookmarks anywhere. Fortunately, I had our desktop computer imaged to my Unraid server, so I recovered them.

Which also illustrates the fact that Unraid can indeed be a backup, just not the only copy of anything important and irreplaceable.

Well said! Any RAID solution with parity is not in itself a backup of irreplaceable data if the RAID server contains the only copy of that data. There needs to be an second copy of that data on some other physical storage media to be a backup! (If the data is replaceable from another source, then that source is (by definition) a backup.)

I image three desktop/laptop computers weekly to my main unRAID server and (as mentioned above) have a second unRAID server that serves as a backup location (drive by drive rsync) for my main server.

Parity does a great job recording all those deletion and file corruption actions! I will sure be glad I have it if there is a need to replace or rebuild a failed drive but data backup is not its purpose.

Exactly. Redundancy is not backup. It is "safer" main storage, but never a backup. Even a single backup on another media is already very risky/unsafe.

Parity will protect from (most) hardware failure for example, but not from viral infection, not from bit rot or anything that would mess up with files. Having another "unattached" copy will allow you to restore a known good (backed up) version.

In the same spirit, synching is not backup either.

It is sort of ironic we have all this chit-chat back and forth about unRAID being a backup or not, but literally on unraid.net, they literally call it a backup solution.

The irony in this thread is amazing

That talks about backing up other data sources to Unraid, backing up Unraid array data to another Unraid server, etc. Nowhere does it say that the Unraid parity protection is a backup of your array data.

I do both of the things mentioned above; backup PCs to Unraid and backup my main server array data to a second Unraid server. I also backup important data to external USB drives and the cloud.

Parity only protects against disk failure and can aid in the recovery of a failed disk if all other array disks are readable but it does not contain any data at all and is, therefore, not a backup.

No irony at all in this thread as it is talking about something completely different than what you linked.

Hoopster is correct.

I back up several systems on my network to my Unraid server array.

I then back up (weekly) the latest few months of those backups to an external drive attached to my Unraid server.

Then every (other?) month, I swap that external drive with another I keep offsite.

The backup on my server is a convenient place to put the backups of the other systems as everything is automated.

The external backup exists if the Unraid server fails, and also can be attached directly to a system that may need to be restored.

Offsite backups are important if the unthinkable happens (fire, flood, etc).

Parity on Unraid helps in the recovery of issues with the system as well as may give an early indication if something is wrong, but it is not a backup of data.

Unraid OS version 6.11.3 available
