While most of backup tools offer file-level recovery for a very small number of file systems, typically, Windows and rarely Linux, Veeam’s multi-OS restore wizard allows you to recover guest OS files from the most commonly used file systems such as Linux, Unix, BSD, MacOS and many others.
For file-level recovery, Veeam Backup & Replication uses a special FLR helper — a small virtual appliance based on the stripped-down Linux kernel. When you perform file-level restore, Veeam Backup & Replication automatically starts the appliance and mounts VM disks to the FLR appliance as virtual hard drives. Virtual disks are mounted directly from backup files, without prior extraction of the backup content, which makes the restore process much faster in comparison with competitive solutions. You can then copy individual files and folders from VM disks to your local machine drive or a network share.
- You can restore VM guest files from any backup that has been successfully run at least once. Open the Backup & Replication view, select the Backups node in the inventory pane. Then expand the backup job and check if there is at least one restore point available for the VM.
- Encrypted LVM volumes are not supported.
To restore guest OS files from the backup of a Linux-based VM or other non-Windows VM:
- Open the Backup & Replication view.
- In the inventory pane, select the Backups > Disk node. Expand the backup job in the working area, right-click the necessary VM in the corresponding backup job and choose Restore guest files > Linux and other.
- At the Restore Point step of the wizard, select the necessary restore point.
- At the Reason step of the wizard, specify the reason for future reference.
- At the last step of the wizard, click Customize to specify settings for the FLR appliance. Select an ESX(i) host, resource pool and the network on which the FLR appliance will run.
If you are restoring files from the NSS file system, select the Restore from Novell Storage Services (NSS) file system check box.
- At the last step of the wizard, click Finish. Note that the FLR appliance usually takes 20 seconds or less to boot.
- Veeam Backup & Replication will display the Backup Browser with the file system tree of the VM. Right-click a file or folder, select Copy To to open the Select Destination window. In the Server field, choose a server to which you want to restore files. In the Path to folder field, specify a destination folder.
- If you are restoring files to the original Linux host, select the Preserve permissions and ownership check box so that all user access permissions for the file are preserved in the restored copy.
- Click Restore.
- Rescan the file hierarchy on the backup server.
Open the Backup Infrastructure view. In the inventory pane, select Managed Servers. In the list of managed servers, right-click the server to which you restored files, and choose Rescan. Wait for the rescan task to complete and close the window with rescan results.
- Check restored files on the backup server.
Open the Files view. In the inventory pane, expand the file tree under the backup server. Select the destination folder and make sure that the restored files or folders are available there.
