USB Hard drives for VM exports

olivierlambert

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

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 dd

dd 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.
