Extended Attributes
attributes for objects on PC desktops or servers running operating systems that use extended attributes.
Since many operating systems use extended attributes, this option can affect backups from servers and
PC desktops running different operating systems. If this option is unchecked, Data Protector Express
filters out the extended attributes during a backup job. As a result, these attributes will not be available
during a restore job.
Macintosh Finder
for files and directories on PC desktops or files servers that are using the Macintosh file system. If this
option is unchecked, Data Protector Express filters out the Finder information that it receives from the
network during a backup job and that it would transmit across the network during a restore job.
Object Owner
information for files and directories on PC desktops or file or application servers running NetWare. If this
option is unchecked, Data Protector Express filters out the object owner information that it receives from
the network during a backup job and that it would transmit across the network during a restore job.
Hardware Compression
compression. This feature only works on devices that support software control of hardware compression.

Settings for Windows

Settings for Windows platforms do not require changing during backup jobs.
For information on platform-specific settings for this platform while running restore jobs, see
Settings for Windows.
Recover databases
restore is complete.

Encryption

Encryption is the process of changing data into a form that cannot be read until it is deciphered,
protecting the data from unauthorized access and use. Company policy normally determines when
encryption is required.
For example, it may be mandatory for company confidential and financial data, but not for personal data.
Company policy will also define how encryption keys should be generated and managed.
The current version of Data Protector Express provides the user with the ability to encrypt the data that is
written to the media and fully implements the Advanced Encryption Standard (AES) for both hardware
and software encryption.
• Hardware encryption is supported on some backup devices, such as HP LTO-4 tape drives. It is
faster than software encryption and requires no processing on the backup server. The encryption
strength is determined by the backup device. HP LTO-4 tape drives always provide strong AES-256
encryption. This feature can be managed by a backup application that supports hardware
encryption, such as Data Protector Express.
• Software encryption uses the encryption algorithms available within Data Protector Express. The
user selects an encryption strength: Low 56 bit, Medium 128-bit or High 256-bit. Each encryption
key size causes the algorithm to behave slightly differently. Increasing software encryption strength
makes the data more secure, but requires more processing power.
