Cloud backup:
It is possible to specify a cloud subscription registration code during local installation of Acronis Backup in Windows. The subscription is registered automatically if the machine is connected to the Internet. Acronis License Server does not accept cloud subscriptions.
A registered subscription for Server or for PC is activated automatically when the first backup to cloud starts, if all subscriptions available in your account are the same type and have the same storage quota.
Deduplication:
3 GB of RAM per 1 TB of unique data are required, instead of 16 GB.
Faster server-side deduplication.
Faster compacting of the data store.
Centralized management:
A centralized vault can be created on an NFS share.
Backup to NFS can be performed by Agent for Linux, Agent for VMware (Virtual Appliance), or Linux-based bootable media.
Virtualization:
The memory size of Agent for VMware (Virtual Appliance) is set automatically, based on the host memory, when the agent is deployed from the management server.
Acronis Backup Advanced for Hyper-V fully supports Generation 2 virtual machines.
Acronis Backup Advanced for Hyper-V can be installed in Windows 8, 8.1 (x64) with Hyper-V.

It is impossible to browse the contents of a managed vault if there are large number of backups running simultaneously to that vault. The storage node that manages the vault hangs.
It is impossible to browse a managed vault from Linux-based bootable media if the storage node that manages this vault also manages another vault that is inaccessible.
Acronis Management Server Service may hang on start.
Acronis Management Server Service is slow to start.
Sometimes, not all backups selected for deletion are deleted.
Tapes:

New in Acronis Backup for Windows Server Essentials 11.0.17217 (Jun 24, 2011)

Disaster Recovery and Data Protection in one unified solution:
Catalog and search capabilities give you granular access to specific data within a backup, so you get the benefits of bare-metal restore and backup in one product
The unified platform dovetails seamlessly with Acronis’ granular application recovery modules such as for Microsoft Exchange Server and Microsoft SQL Server
Integrated tape management improves support for tape and tape autoloaders, allowing you to store, replicate or stage backups to tape – either image, file or application
Improved core-disaster recovery:
Acronis Universal Restore for Linux extends our award-winning Acronis Universal Restore technology to Linux systems, allowing you to recover to dissimilar hardware
Universal Restore bootability lets Acronis Universal Restore technology make Windows or Linux bootable again after replacing hardware
Backup and recovery of systems that use UEFI/GPT
Full support for new disk with 4K sectors and SSD
Backup and recovery of Linux systems that use LVM
Take advantage of hardware built-in snapshot to offload processing from production servers
Reduce long-term storage costs with staging, and add redundancy with multi-destination:
Move old backups to tape (D2D2T) or to less expensive disk (D2D2D)
Store multiple backups locally and remotely on disk and in the cloud
Back up to the cloud directly (D2C) or indirectly (D2D2C1)
Improved deduplication performance, capacity and scalability offers you even greater savings
Improved support for virtualized environment:
Simultaneous backup of multiple virtual machines, even served with the same agent, allows you to shorten the backup window
Windows agent for ESX(i), an alternative to ESX(i) virtual appliance, lets you offload backup traffic from ESX(i) hosts to a dedicated Windows machine and achieve real LAN-free backup
Load balancing between ESX(i) agents automatically distributes tasks between a number of agents to optimize performance. One virtual appliance or agent may serve as many ESX(i) hosts as required, and more agents may be added when needed.
Hyper-V clusters and CSV support lets you benefit from agent-less virtual-machine backup even in clustered Hyper-V environments
Improved Instant Restore™ shortens recovery time by only applying incremental changes and allows for better RPO
Disaster Recovery Plan:
Automatically generated each time a backup completes, containing step-by-step instructions in case an IT administrator is not available
More management options:
New alerts with email notifications provide you with a complete list of problems, such as task failures and warnings, such as low disk space
Configure a backup plan on one machine, export it to an XML file and import it on other machines
Vault permissions give better control over who can access what data in the vaults
New command-line interface will be handy for companies looking for automation and integration
