There are two types of disk available: basic and dynamic disk. These disks are used for creating partitions using writing tables like MBR, EBR, LDM and GPT.
- In the MBR partition, 3 standard primary partitions are created and one logical volume or 4 primary partitions in disk of up to 2 TB.
- In GPT partition, 128 primary partitions are created on a disk of up to 64TB.
In its previous versions of BDR, Vembu did not support backups for disks larger than 2 TB or GPT disk format. Now with Vembu BDR v2.1.0 (BETA), the support for backup of GPT partition and disks larger than 2TB. When an older version of BDR, is upgraded to v2.1.0 GA release the user can configure a disk image backup using GPT and be able to use a disk larger than 2TB (v2.1.0 BETA is not supported for upgrade of older version).
Disk image backup support is available while meeting the following criterias:
| Parameters | Supported | Not Supported |
|---|---|---|
| Disk type | Basic / Dynamic | – |
| Writing tables | MBR, EBR, LDM and GPT partition. | – |
| Partition style | Primary, Extended, and Dynamic all type of volumes. | – |
| File system | NTFS | ReFS, FAT |
| Sector Size | 512-byte (Emulation) | 4K sectors |
| RAID | 0, 5, and 6 (tested) | – |
We have support recovery options and they are:
- P2V: Instant boot option for disk larger than 2TB and GPT backups.
- P2P: Disk restore using Vembu DR UI.
We support more than 2TB and GPT disk image in both Windows and Linux operating systems. Instant boot feature support is currently available for Windows 2012 R2 Datacenter and Standard version, and support for Windows 2008 R2 and Linux features is under product research. For more than 2TB sized and GPT disk image backup, the download is available with download as VHDX option.
