USB Hard drives for VM exports
-
So you'd like to avoid another server to store the backup? I would say it's doable, but if you can buy a very cheap NAS with NFS, put it in another room, you'll get FAR more security for a low cost.

Hello Oliver
I didnt understand why a NAS is more save than a local to XO connectet hard drive ?
And need mutch more energie.. And more Networktrafic...My my coustumer can change the HDD every day and wie let run the Exports of snapshout by nigth.
If i store the exports via NAS external the networktrafic is doubel high.. Move them the XO mashine than to the NAS.
And i need 2 NAS systems to leave the officce.. (when the officie is burning down or sombody seal the IT - stuff.
Coutryside has no good Internet Infrastrukture (symetric fiber cahnale with 100 or 200Gbit can costs 1000€ per month if ther is some) and we pay around 030€/kW
My costumer had VDSL2 wich 300/50Mbit so ist no option to sore it external ..

- Because if your server is taking fire/water/electrical or any physical issue, having a box at another place (even just at another room close to it) is far far far safer. Really, it worth every $ of this very low investment.
- XO backups aren't meant to work like that. If you want to plug/unplug the HDD, this will require something in XO VM to be able to get the mount working when needed.
- Having a HDD plugged for "ever" will work, but you are in case 1. in terms of safety

Sorry I don't understand what you meant.

on witch place i had to mount the HDD ?

You'll need to pass the drive directly to XOA VM. Plug the USB HDD, and then you should be able to add it in the VM view/disk tab, Attach, select the USB drive. That's it.

Now i am moving a step forward :-). I dont let XO runing in a VM my XO is running on a Thin-Client (HP620 16GSSD and 4GByte RAM 1GBit Nic) with Debian. The Debian installation was a lill bit tricky but now its running. Thanks for the debian / ubuntu install script is running perfekt.
The USB3.0 HDD is connectet and mounted on /Backup.
Reading from USB drive with dddd if=/dev/sdb1 of=/dev/null bs=100M count=10
Result 130MByte/sec
Debian and XO needs fresh 1,7Gbyte HDD-Space.
My XCP-NG servers are found with there VMs
Next step testing Backup ...
thx Axel

I tested backup directly to USB drives by attaching to the XO VM. Backup and restore works fine as long as I restore the whole VM from USB.
If I try to drill down and restore an individual file from the backup on USB I cannot.
Is there a way to do this?
-
@indyj FYI when I ran this test again it worked.
this time:- I ran it as a "Delta" backup.
- And then rescanned the removable media.
- I was then able to restore an individual file from the backup on USB media.
