dynamic volumes' configuration. Each dynamic disk holds the complete information about all
dynamic volumes existing in the disk group which makes for better storage reliability. The database
occupies the last 1MB of an MBR disk. On a GPT disk, Windows creates the dedicated LDM Metadata
partition, taking space from the Microsoft Reserved Partition (MSR.)

Dynamic group
A group of machines (p. 446) which is populated automatically by the management server (p. 447)
according to membership criteria specified by the administrator. Acronis Backup offers the following
membership criteria:
 Operating system
 Active Directory organizational unit
 IP address range
 Listed in txt/csv file.
A machine remains in a dynamic group as long as the machine meets the group's criteria. However,
the administrator can specify exclusions and not include certain machines in the dynamic group even
if they meet the criteria.
Dynamic volume
Any volume located on dynamic disks (p. 443), or more precisely, on a disk group (p. 443). Dynamic
volumes can span multiple disks. Dynamic volumes are usually configured depending on the desired
goal:
 to increase the volume size (a spanned volume)
 to reduce the access time (a striped volume)
 to achieve fault tolerance by introducing redundancy (mirrored and RAID-5 volumes.)
