 If the volume is a compressed volume

 If the volume's allocation unit size—also known as cluster size or block size—is not divisible by

4 KB

Tip: The allocation unit size on most NTFS and ext3 volumes is 4 KB and so allows for block-level

deduplication. Other examples of allocation unit sizes allowing for block-level deduplication include 8 KB,

16 KB, and 64 KB.

 If you protected the archive with a password

Tip: If you want to protect the data in the archive while still allowing it to be deduplicated, leave the archive

non-password-protected and encrypt the deduplicating vault itself with a password, which you can do

when creating the vault.

Disk blocks that were not deduplicated are stored in the archive as they would be in a non-

deduplicating vault.

File-level deduplication restrictions

During a file backup to an archive in a deduplicating vault, deduplication of a file is not performed in

the following cases:

 If the file is encrypted and the In archives, store encrypted files in decrypted state check box in

the backup options is cleared (it is cleared by default)

 If the file is less than 4 KB in size

 If you protected the archive with a password

Files that were not deduplicated are stored in the archive as they would be in a non-deduplicating

vault.

Deduplication and NTFS data streams

In the NTFS file system, a file may have one or more additional sets of data associated with it—often

called alternate data streams.

When such file is backed up, so are all its alternate data streams. However, these streams are never

deduplicated—even when the file itself is.

2.14.7 Privileges for centralized management

This section describes the users' privileges that are required to manage a machine locally and

remotely, to manage a machine registered on Acronis Backup & Recovery 10 Management Server,

and to access and manage Acronis Backup & Recovery 10 Storage Node.

Types of connection to a managed machine

There are two types of connection to a managed machine: local connection and remote connection.

Local connection

The local connection is established between Acronis Backup & Recovery 10 Management Console on

a machine and Acronis Backup & Recovery 10 Agent on the same machine.

To establish a local connection

 On the toolbar, click Connect, then point to New connection, and then click This machine.
