New in Acronis Backup Advanced 11.7.44179 (Feb 27, 2016)

WHAT'S NEW:
Installation:
Microsoft SQL Server 2014 can be used to store the databases of Acronis Backup Management Server
Deduplication:
128 MB of RAM per 1 TB of unique data are required, instead of 3 GB.
No need to allocate the deduplication database on expensive SSD disks. Regular HDD disks can be used without performance degradation.
Recovery from a deduplicated backup is now 40 percent faster.
The backup speed does not reduce as the deduplication database size increases.
The Storage Node startup time on large data sets is reduced to 1-3 minutes.
Validating deduplicated backups and compacting the data store are now 2.5 times faster.
These improvements are effective when v11.7 agents back up to deduplicating vaults created on v11.7 storage nodes. When a new agent backs up to an old vault or an old agent backs up to a new vault, the old deduplication algorithm is used. To apply the new deduplication algorithm to old backups, you need to import the backups into a newly created vault.
Tape support:
Configurable block size for reading and writing to tapes. The default value is taken from the tape device driver.
Hardware Compatibility List (HCL) and Hardware Compatibility Tool are introduced. Hardware Compatibility List contains tape devices with confirmed support by Acronis Backup. To learn if your specific device is supported, use the Hardware Compatibility Tool.
Full support for the LTO-7 technology. See the HCL for the exact names of the tested devices.
Centralized management:
It is possible to specify a custom backup location for each machine that is included in a centralized backup plan.
In addition to exporting licenses from the management server to an .xml file, you can export them to a .txt file.
Microsoft Exchange Server support:
Agent for Exchange can back up and recover Microsoft Exchange Server 2016 databases. Backup and recovery of Exchange 2016 mailboxes (including mailbox recovery from database backups) are not supported.
Other:
It is possible to use compression in combination with third-party hardware or software deduplication (for disk-level backups only). This effectively reduces the storage space occupied by the backups.
More functionality is available via the command-line interface:
Generating management server reports
Deploying Agent for VMware (Virtual Appliance)
Agent for VMware does not back up independent disks and Raw Device Mapping (RDM) disks in physical compatibility mode, regardless of the state of a virtual machine. This limitation is introduced for better predictability of the product behavior.
32-bit Linux-based bootable media was optimized in size by removing the rarely used acrocmd utility.
When a disk backup is mounted in the read/write mode, the respective incremental backup is not created immediately, but after the disk backup is unmounted, instead. While the backup is mounted, the changes are saved in the %Temp% folder.
FIXED ISSUES:
Installation:
[ABR-72208] Installation on SuSE Linux 8.2 fails. The following error appears: "--nopostun: unknown option".
[ABR-35597] During Acronis Backup installation on a XenServer machine with Windows XP, Windows Small Business Server 2011, or Windows Server 2012 R2 guest operating system, license Acronis Backup Advanced for Citrix XenServer is not accepted.

[ABR-82971] Acronis Universal Restore does not automatically set '0' as the "DisableCDDB" value data in the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PnP. It leads to a system crash with error 0x0000007B ("INACCESSIBLE_BOOT_DEVICE").
Note: The fix works only if the "DisableCDDB" value is created locally (not through Group Policy).
[ABR-82513] Acronis Universal Restore fails to apply drivers after the recovery if the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services key in the recovered Windows registry contains more than 504 subkeys.
[ABR-76406] The mouse and the keyboard are not detected on a Microsoft Surface Pro 3 tablet booted from Linux-based bootable media.
[ABR-75882] Bootability recovery fails with incorrect GRUB loader record (the root definition is wrong).
[TTASK-11504] Acronis Managed Machine Service crashes on a machine with a specific GPT header present on disk.

[ABR-71497] Scheduled alert notifications configured in the management server options use the UTC time zone instead of the local time.
[ABR-71184] Acronis Backup Management Server uses 98% of CPU when browsing a centralized vault located on a corrupted storage.
[ABR-69913] Acronis Backup Management Server may crash after an update from Version 11.5 Update 5.
[ABR-66893] The Network connection speed backup option does not work when the backup destination is a deduplicating vault.
[ABR-66442] Centralized backups of logical volumes by using selection rules (for example, "/dev/VolGroup/lv_root") fail. The following error appears: "Cannot resolve any inclusion rule."
Applications support:
[TTASK-11553] Acronis Backup may fail to browse an Exchange information store while creating a backup plan.
[ABR-83250] Recovering contacts from an Exchange 2010 public folder fails. The following error appears: "The optional value is null."
Tapes:
[ABR-68221] The operation of moving tapes to another slot may fail on a Hyper-V virtual machine.
Virtualization:
[ABR-84006] The conversion of an EFI machine to a virtual machine from an incremental backup fails while the conversion of the same machine from a full backup is successful. The following error appears: "Failed to prepare operations. Error code: 7 'Disk is not found. Make sure that all the hard disks are installed in your computer.'"
[ABR-82538] While a machine running Windows Server 2012 R2 is being recovered to a new ESX(i) virtual machine, the following warning appears: "Device driver 'PCI\VEN_1000&DEV_0030&SUBSYS_00000000&REV_01' for 'Windows Server 2012 R2' cannot be found." The resulting VM is unbootable.
[ABR-82514] After a machine running Windows Server 2012 R2 is backed up and recovered to a new ESX(i) virtual machine, the resulting VM does not contain valid network interface cards. The cards have to be added manually.
[ABR-82354] A backup of a virtual machine fails after the machine was migrated (via vMotion) between hosts of an ESX(i) cluster, if "Disks/Volumes" was selected in "What to back up".
[ABR-82316] A backup of a Generation 2 virtual machine with converting to a Hyper-V virtual machine fails. The following error appears: "The bus type is invalid."
[ABR-81018] If a backup contains a disk larger than 2 TB, it is not possible to add a virtual disk larger than 2 TB while configuring recovery from this backup to a new ESX(i) virtual machine.
