Requirements and Limitations

In this article

    Before you restore VM guest OS files, mind the following requirements and limitations.

    Requirements

    Consider the following general requirements:

    • You can restore files from the file systems listed in the Platform Support section.
    • The account that you use to start the Veeam Backup & Replication console and to connect to the backup server must have permissions and privileges described in Veeam Backup & Replication Console Permissions.
    • You can restore VM guest OS files from a backup that has at least one successfully created restore point.
    • [For restore to the original location] VM guest OS must be accessible from the backup server over the network, or over PowerShell Direct (for VMs that reside on Microsoft Hyper-V Server 2016 or later).
    • [For restore to the original location] Hyper-V Integration Services must be installed on the target VM.

    Requirements for ReFS

    If you plan to restore files from a VM running Microsoft Windows ReFS, consider the following requirements for the Veeam Backup & Replication components involved in the restore process:

    To learn in which scenarios on which machines mount points are created, see Mount Points and Restore Scenarios.

    Requirements for Data Deduplication

    If you plan to restore files from a VM running Microsoft Windows Server 2012 or later and data deduplication is enabled for some VM volumes, consider the following for the Veeam Backup & Replication components involved in the restore process:

    To learn in which scenarios on which machines mount points can be created, see Mount Points and Restore Scenarios.

    Limitations

    Consider the following limitations:

    • You cannot restore pipes and other file system objects. File-level restore supports recovery of files and folders only.
    • You can restore files from basic disks and dynamic disks (including simple, mirrored and striped volumes).
    • Processing of reparse points is supported only for NTFS. Note that reparse points with reparse tag values other than IO_REPARSE_TAG_MOUNT_POINT, IO_REPARSE_TAG_SYMLINK and IO_REPARSE_TAG_DEDUP may be processed and restored incorrectly.
    • You cannot restore files from a backup created in the reverse incremental mode if the backup job is being performed. If the backup is created in the incremental backup mode and the backup job is being performed, you can restore files from any available restore point.
    • You cannot restore VM guest OS files to the original location if you have excluded the system disk from the VM backup used for restore and the volume GUID of the system disk was changed after the VM backup creation.
    • Also, see limitations in the VM section.
