Encryption as a machine property

This option is intended for administrators who handle backups of multiple machines. If you need a

unique encryption password for each machine or if you need to enforce encryption of backups

regardless of the backup plan encryption settings, save the encryption settings on each machine

individually.

Saving the encryption settings on a machine does not affect the currently applied backup plans, but

will override the encryption settings of all backup plans applied later. Any backup created by these

backup plans will be encrypted, even if encryption is disabled. After the settings are saved, they

cannot be modified, but you can reset them as described below.

This option is available for machines running Windows or Linux. It is not supported for OS X.

This option can be used on a machine running Agent for VMware. However, be careful if you have

more than one Agent for VMware connected to the same vCenter Server. It is mandatory to use the

same encryption settings for all of the agents, because there is a kind of load balancing among them.

To save the encryption settings on a machine

1. Log on as an administrator (in Windows) or the root user (in Linux).

2. Run the following script:

 In Windows: <installation_path>\PyShell\bin\acropsh.exe -m manage_creds

--set-password <encryption_password>

Here, <installation_path> is the backup agent installation path. By default, it is

%ProgramFiles%\BackupClient in 32-bit Windows and %ProgramFiles(x86)%\BackupClient

in 64-bit Windows.

 In Linux: /usr/sbin/acropsh -m manage_creds --set-password <encryption_password>

The backups will be encrypted using the AES algorithm with a 256-bit key.

To reset the encryption settings on a machine

1. Log on as an administrator (in Windows) or root user (in Linux).

2. Run the following script:

 In Windows: <installation_path>\PyShell\bin\acropsh.exe -m manage_creds --reset

Here, <installation_path> is the backup agent installation path. By default, it is

%ProgramFiles%\BackupClient in 32-bit Windows and %ProgramFiles(x86)%\BackupClient

in 64-bit Windows.

 In Linux: /usr/sbin/acropsh -m manage_creds --reset

Important After you reset the encryption settings on a machine, the backups of this machine will fail. To

continue backing up the machine, create a new backup plan.

How the encryption works

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 larger the key size, the

longer it will take for the program to encrypt the backups and the more secure your data will be.

The encryption key is then encrypted with AES-256 using an SHA-256 hash of the password as a key.

The password itself is not stored anywhere on the disk or in the backups; 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.
