Settings for drive imaging

O&O DiskImage-30

Encryption

Your data can be securely encrypted using the recognized AES method. This permits O&ODiskImage to provide your

image with an extremely high level of security with a key length of up to 256 bits.

l You can select the encryption level for your files under Drive imaging/Imaging options/Image file/Security.

l If you then start the imaging process (Drive imagings), enter a password when being prompted.

A belated encryption of the image is possible under Convert image file.

Compress image

Under Drive imaging/Imaging options/Image file you find the settings Compress image file to save storage

space. You can choose from the LZNT1 Standard or theBZIP2 process.

LZNT1:This is a compression type based on the Lempel-Ziv algorithm, which is laid out on a real time application.

Speed is preferred over the rate of data compression.

BZIP2: is a block type compression process. Compression rate is preferred over velocity.

You can also compress the image after creation under Convert image file in the Tools menu.

Note: Compression increases the time required to create an image file. However, the file then requires less space

on the disk.

Exclude files from an image

Note: Several minutes may be needed for excluding files, depending on the amount of data on the hard disk.
