Limitations of "Windows Backup" RRS feed

All replies

  • Hi,

    The limitation is not from Windows Server Backup (WSB), but from the NTFS file system. 

    You'll find the limitations over here:
    Default cluster size for NTFS, FAT, and exFAT

    By default Windows servers/Windows clients use 4K cluster size for NTFS volumes, which means the maximum size is 16TB, if you were to use a bigger cluster size for example 8K, you could use disks up to 32TB.

    Note: The cluster size represents the smallest amount of disk space that can be used to hold a file.

    Best regards,
    Leon

  • Source filesystem is "Refs" with 64k cluster size.

  • Windows Server Backup should be able to back up that, if the disks are bigger than 16TB then all you need to make sure that the cluster size is big enough, both on source and destination.

  • I believe Windows Server Backup doesn't support backing up ReFS volumes. ReFS file system used only for storage target as far as backup is concerned.

    There are third party backup software which can take backup of ReFS file systems.

  • Hi,

    Thanks for posting in our forum!

    Windows Server Backup doesn’t support backup REFS volume, I believe that this function will be implemented in the near future, but at present we need to use third-party backup tools to backup REFS volumes. From my personal point of view, I recommend that you use VEEAM.

    For more question about how to use VEEAM, you can discuss with their experts over here:
