USB Hard drives for VM exports



  • Hello

    I am trying XO looks nice. My installation is very smal. The are two serves as a "HA" cluster (yes more are better) and a apklication server. HA with HA Lizard. So there ar now three servers and a very small head with XO. I am using a HP-Thinclient with 4GYte RAM an 16GByte SSD. It runs fine, I try the xcp update it runns perfect.

    Now i will try the export VMs. Will be pefect on a external USB3.0 Disk.

    Will be nice to had a button 4 mounting/unmounting USB Drives.

    It is possibel to store the export files localy ?

    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 ..

    1. 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.
    2. 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.
    3. Having a HDD plugged for "ever" will work, but you are in case 1. in terms of safety

    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.
