I don't know anything that will attach via USB that will be able to pull this off. You will need a more serious storage device to be able to handle it.
It depends on what you are trying to accomplish.
For just protecting from a VM blowup, why not attach a USB as a SR? That would work, no? I know in the past you said no one attaches USB drives to servers, but not sure I believe that.
Of course that doesn't protect from a disaster with the machine itself.
Sure people attached USB's to servers because they are bidding their time, hoping it doesn't fail, trying to accomplish something with as little as possible.
For a scenario like this that @PRPL is in he could* build his own backup server from parts he has lying around, he needs at most 4TB of space.
To build something new for this would be incredibly cheap (recommended no, likely not) but as an absolute stop gap before using a USB to backup; a cheap "whitebox" server with the storage needed would be vastly better.

One of the reasons that USB Drives don't work in this scenario is that you need two different backup systems, totally independent from each other, to handle the two servers. And then there is no clear means of restoring in the case of a server failure without hardware changes. And in the case of a breach, the backups are totally exposed (tightly coupled) at all times to the server. So if someone got access to the server, not only is your server at risk, but they will "own" all of your backups too. To the point that it is only marginally possible to even call this a backup, technically the USB drive is external, but it is so physically close and so much just a slow, internal drive that it's more a copy, less a backup.

In a smallish shop, the server you are backing up to is probably pretty close tot he actual server.
We're not talking offsite redundancy here.
You could throw Linux on a spare machine and accomplish what you are looking for pretty cheaply.

And that is what should be recommended, avoid using USB's as the "backup target" and get a decent system with the capacity needed and backup to that.
In linux setting up an CIFS/NFS server is trivial and takes minutes at most.

And that's why USB drives are never used... there is always a better, simpler way.

IF you have a spare machine sitting around.
(Yes, I am kidding.)

hmm... We have around 600 - 700GB of data, on 1 server .. , and around 200 - 250GB on another ...
So which machine has the 1TB VM?
None ... I just used 1TB to get an idea of the restore time-frame ....

We have desktops, almost all of them have 500GB disks ... These are used, simply to host the Operating System and client-side applications, which lie on a 100 - 150GB primary partition... The rest is un-used, which in my opinion is a complete waste ... If somehow, one could pool the free storage from all these desktops (say even 20), then you'd get around 2TB of storage space , good enough for backups ... AetherStor ? The one down-side (?) with AetherStor is that, currently it offers only FAT32 based storage ... I wonder how it would work if we backed-up NTFS files to FAT32
-
@PRPL ÆtherStore will work fine for files but would lose perms if you are using a copy command instead of backup software. If you are using backup software and/or taking snaps it will work just fine.

geez Scott ... when do you get sleep ...
Yes, I was wondering about the permissions ... So, whats your take on the viability of AetherStor, as a proper, production use backup pool (given that I'll use a proper backup software)
-
ÆtherStore can work great for that. As a backup target pool it is really ideal. That's a perfect use case.

No, does not need to be the same. Although Veeam Free will leave you without some of the things that you want. Unitrends or XenOrchestra will likely do a better job for you here when trying to do this for free.
Though no file level.
Always better to have an agent if you need that.
Unitrends does file level. But not for free.
Veeam can also do file level restores (no agent required) but again not in the free product.

This is one of the primary use cases for ÆtherStore that many of the testers used it for, myself included.

Absolutely, when I spent time with @Rob on this, the focus was very heavily to get backups working before anything else. It's the top use case for the product.

Oh, the free version doesn't have that feature? I did not realize that.

Summing up this thread, the biggest thing the OP needs to understand is that he is not a special snowflake (I leave it to @scottalanmiller to link to his post on that). He keeps saying he needs all these various things that he almost certainly does not need.
I am willing to bet real money that no one in his company even took the time to analyze anything related to this.
He currently has a non-virtualized environment FFS. He most certainly does not need < 1 hour restores and HA and pretty much everything else that has been talked about.

This is huge, when you need HA, someone will pretty much tell you numbers for you to work with, things like "We lose $3,500 per hour." Or better, they give graphs that show how much they lose for each hour because it's not flat... it might be $20 the first hour and $10,000 the second hour.
There should also be outage mitigation strategies in a policies and procedures documentation place. People need to understand how to deal with an outage, not just act like the world has ended.

Agreed, it is a huge leap. It's not an organic growth from where they are to an improvement, it's "not treating it like a business" jumping straight to "things normal SMBs do not need." Good things to consider, but likely a single server with solid design is all that is warranted.

Unless it changed in the last year, free Veeam only does full backups as "VeeamZIP" file to my knowledge.
