Restore from Linux, Unix and Other File Systems

The method of restore from Linux, Unix and other file systems helps you restore files from backups or replicas of Linux, Solaris, BSD, Unix and Mac workloads. For the list of supported OSes and file systems, see Platform Support.

You can restore files to the original or new location, access restored files using FTP or launch application item restore for the files. For more information, see Finalize Restore. 

How Restore Works

When you perform guest OS file restore, Veeam Backup & Replication provides the following options for mounting VM disks from the backup or replica:

  • Mounting disks to a helper host. As a helper host, you can select the target host where you want to restore files from the backup or any other Linux server. We recommend you to specify the same server to which you want to restore the files. This will improve the performance.
  • Mounting disks to a helper appliance. The helper appliance is a helper VM running a stripped down Linux kernel that has minimal set of components. The appliance is quite small — around 50 MB. It requires 2048 MB RAM and 2 CPU.

When you perform guest OS file restore, Veeam Backup & Replication performs the following operations:

  1. [If you have selected to mount disks to a helper appliance] Veeam Backup & Replication deploys the helper appliance on the Microsoft Hyper-V host in the virtual infrastructure.
  2. Veeam Backup & Replication mounts disks of a VM from the backup to the helper host or helper appliance. The backup file itself remains in the read-only state in the backup repository or volume.
  3. Veeam Backup & Replication launches the Veeam Backup browser where mounted VM disks are displayed. You can browse the VM guest file system in the Veeam Backup browser and restore files or folders to the original VM or to another location. Also, you can enable an FTP server on the virtual appliance and allow VM owners to restore files themselves.
  4. Depending on which restore command you use, the operations differ:
  • You select the Restore or Restore to command to restore files to the original location or to another Microsoft Hyper-V VM.

If you have installed the Linux Management Agent, the helper host or helper appliance connects to the VM to which you restore files (target VM) using this agent and restores files. This is the preferred way of connection.

The helper host or helper appliance connects to the VM to which you restore files (target VM) over SSH. Then Veeam Backup & Replication deploys on the VM the agent which performs restore.

  • If you restore files to a new location, select the Copy to command.

The helper host or helper appliance connects to the VM to which you restore files (target VM) over the network. Then Veeam Backup & Replication deploys on the VM the agent which performs restore.

  1. When you close the Veeam Backup browser or it is closed by timeout, Veeam Backup & Replication unmounts the content of the backup file from the helper host or helper appliance.
  2. [If you have selected to mount disks to a helper appliance] Veeam Backup & Replication unregisters the helper appliance on the Microsoft Hyper-V host.
