Dynamic group
A group of machines (p. 347) which is populated automatically by the management server (p. 348)
according to membership criteria specified by the administrator. Acronis Backup & Recovery 10 offers
the following membership criteria:
according to membership criteria specified by the administrator. Acronis Backup & Recovery 10 offers
the following membership criteria:
•
Operating system
•
Active Directory organization unit
•
IP address range.
A machine remains in a dynamic group as long as the machine meets the group's criteria. The
machine is removed from the group automatically as soon as
machine is removed from the group automatically as soon as
•
the machine's properties change so that the machine does not meet the criteria anymore OR
•
the administrator changes the criteria so that the machine does not meet them anymore.
There is no way to remove a machine from a dynamic group manually except for deleting the
machine from the management server.
machine from the management server.
Dynamic volume
Any volume located on dynamic disks (p. 345), or more precisely, on a disk group (p. 344). Dynamic
volumes can span multiple disks. Dynamic volumes are usually configured depending on the desired
goal:
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.)

Encrypted archive
A backup archive (p. 339) encrypted according to the Advanced Encryption Standard (AES). When the
encryption option and a password for the archive are set in the backup options (p. 340), each backup
belonging to the archive is encrypted by the agent (p. 339) before saving the backup to its
destination.
encryption option and a password for the archive are set in the backup options (p. 340), each backup
belonging to the archive is encrypted by the agent (p. 339) before saving the backup to its
destination.
The AES cryptographic algorithm operates in the Cipher-block chaining (CBC) mode and uses a
randomly generated key with a user-defined size of 128, 192 or 256 bits. The encryption key is then
encrypted with AES-256 using a SHA-256 hash of the password as a key. The password itself is not
stored anywhere on the disk or in the backup file; the password hash is used for verification
purposes. With this two-level security, the backup data is protected from any unauthorized access,
but recovering a lost password is not possible.
