File backup options

Regulate the size of a file backup

A file backup can be split into multiple backup files. If one disk is not enough for storing a complete backup, you will

automatically be asked to indicate a different storage location. It is also possible to manually set the maximum size of

an file before. If the image being created is larger than the entered file size, additional image files will be created.

This function is especially useful when you plan to burn your image onto a CD/DVD at a later time. Sometimes a

CD/DVD is not large enough to contain the entire image file. We recommend limiting image files to the size of the blank

CD/DVD onto which you will be writing your images.

The image file can also be split at a later time using the Convert image file function. It is, however, recommended to

split images at the time they are created to avoid any confusion that may arise.

l Under File backup/File backup options/File size/Split image into smaller image files with fixed sizes you

can specify the size of individual image files.

Encrypt file backup

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

extremely high security levels with a key length of up to 256 bits.

l You can select the level of encryption for your files under File backup/File backup options/Security.

l If you then start the imaging process (Start file backup), enter a password when being prompted.

You also have the option of encrypting the image after it's been created under Convert image file.

File backup advanced settings

You can specify further settings under Advanced in the File backup options .

Lock drive while imaging

While processing a file backup, you can lock the drive where the folders/files being backed up are located. This pre-

vents any changes from being made to the drive while the backup is being created. The drive will no longer be dis-

played in Explorer and all applications will be closed. The drive is not locked by default. If the drive is not locked,

changes will be buffered either in the snapshot cache (if installed) or over the volume shadow copy service of Windows

so that these changed won't influence the backup.

Use check sums to administer unchanged data (for incremental file backup)

Unchanged data is saved by default using checksums by the method Image of the changes. The file is slightly larger.

It's therefore enough if you enter an existing image of the changes as source image for the next Image of the

changes(with checksums). This function is enabled by default. If you save all images in a single folder, you can also

disable this function. Your images will then take up less space on the disk.

l Make sure that the optionUse checksums to administer unchanged data under File backup/File backup

options/Advanced is enabled.

Apply profiles for file backups

Under File backup/File backup options/Current profile you can reset the current settings to default for the image or

select a wide ranging user-defined profile.

If you would like to save your user-defined settings, please follow these instructions:

1 2 ... 39 40 41 42 43 44 45 46 47 48 49 ... 107 108
