Backing up a virtual machine means backing up all the machine's disks plus the machine

configuration. With this source type, you can back up multiple machines. This comes in handy when

having small (in terms of virtual disks size) but numerous legacy servers such as those resulting from

workload consolidation. A separate archive will be created for each machine.

Volumes of a virtual machine

Available if Acronis Backup & Recovery 10 Agent for Hyper-V (or for ESX/ESXi) is installed.

Select this option to back up individual disks or volumes within a virtual machine residing on a

virtualization server.

With this source type, you select the machine and then select the disks/volumes to back up. This

comes in handy when the operating system and applications, such as a database server, run on a

virtual disk, but the data, such as a database, is stored on a large capacity physical disk added to the

same machine. You will be able to use different backup strategies for the virtual disk and the physical

storage.

6.2.4 Items to back up

The items to backup depend on the source type (p. 198) selected previously.

Selecting disks and volumes

To specify disks/volumes to back up

1. Select the check boxes for the disks and/or volumes to back up. You can select a random set of

disks and volumes.

If your operating system and its loader reside on different volumes, always include both volumes in the

backup. The volumes must also be recovered together; otherwise there is a high risk that the operating

system will not start.

2. [Optional] To create an exact copy of a disk or volume on a physical level, select the Back up

sector-by-sector check box. The resulting backup will be equal in size to the disk being backed up

(if the Compression level option is set to “None”). Use the sector-by-sector backup for backing up

drives with unrecognized or unsupported file systems and other proprietary data formats.

3. Click OK.

What does a disk or volume backup store?

For supported file systems, with the sector-by-sector option turned off, a disk or volume backup

stores only those sectors that contain data. This reduces the resulting backup size and speeds up the

backup and recovery operations.

Windows

The swap file (pagefile.sys) and the file that keeps the RAM content when the machine goes into

hibernation (hiberfil.sys) are not backed up. After recovery, the files will be re-created in the

appropriate place with the zero size.

A volume backup stores all other files and folders of the selected volume independent of their

attributes (including hidden and system files), the boot record, the file allocation table (FAT) if it

exists, the root and the zero track of the hard disk with the master boot record (MBR). The boot

code of GPT volumes is not backed up.

A disk backup stores all volumes of the selected disk (including hidden volumes such as the

vendor's maintenance partitions) and the zero track with the master boot record.
