Exporting data from Compute disks and shared filesystems

You can export data that you store on Compute volumes (boot disks, additional disks and shared filesystems) to local or virtual machines:

1. Check whether the disk or filesystem is used on any VMs:

   Web console

   1. In the web console, go to Storage → Disks or Storage → Shared filesystems.
   2. Click on the volume.
   3. Under General, check the Virtual machine value. It lists the VMs that use the volume.

   CLI

   • For a disk, run nebius compute disk list or nebius compute disk get <disk_ID>. If the disk is used on a VM, the output contains the VM’s ID in the .status.read_write_attachment field:

     status:
       read_write_attachment: computeinstance-e00***
     

     For more details about the commands, see the references for nebius compute disk list and nebius compute disk get.

   • For a filesystem, run nebius compute filesystem list or nebius compute filesystem get <filesystem_ID>. If the filesystem is used on any VMs, the output lists their IDs in the .status.read_write_attachments field:

     status:
       read_write_attachments:
         - computeinstance-e00***
         - computeinstance-e00***
     

     For more details about the commands, see the references for nebius compute filesystem list and nebius compute filesystem get.

2. If the disk or filesystem is not used on any VM, attach and mount it to a VM.

3. Check that you can connect to the VM over SSH.

   What to do if I cannot connect to the VM

   • If the VM does not have a public IP address, you have the following options:

     • Connect to the VM’s private address from another VM in the same network.

     • Run nebius compute instance update with the --network-interfaces parameter to add a public address to the VM. For the command reference, see nebius compute instance update.

     • Create another VM with a public address and add the volume to it. For details and examples, see How to create a virtual machine in Nebius AI Cloud.

       One disk can be used on one VM at a time. To add a disk to a new VM, you need to detach the disk from the original VM if it is an additional (secondary) disk, or delete the original VM altogether if the disk is the VM’s boot disk. This restriction does not apply to shared filesystems.

   • If you have not created this VM, ask its owner to perform the following steps themselves or add you to the VM as a user.

   • For other connection issues, contact support.

4. On your local machine, run a tool for copying files, for example, rsync or scp:

   rsync

   rsync <username>@<public_IP_address>:</path/to/file(s)/on/VM> </path/to/destination/on/local/machine>
   

   For example, if a VM has the public IP address 195.242.11.11 and you work with it as alice, run the following command to recursively copy the contents of your home directory:

   rsync -r alice@195.242.11.11:/home/alice ~/vm-home
   

   For more rsync details and parameters, run man rsync.

   scp

   scp <username>@<public_IP_address>:</path/to/file(s)/on/VM> </path/to/destination/on/local/machine>
   

   For example, if a VM has the public IP address 195.242.11.11 and you work with it as alice, run the following command to recursively copy the contents of your home directory:

   scp -r alice@195.242.11.11:/home/alice ~/vm-home
   

   For more scp details and parameters, see its manpage or run man scp.
