2.1.6 Image’s data compression level

In the next Compression level window you’ll need to select a data

compression level of a partition image. A compression level can be selected

by moving the slider (Figure 2.8). If you select zero compression, files will be

obviously moved to an archive file without any compression, which is

inefficient. On the other hand the work speed might drop and image creation

time might increase, if you select the maximal compression. Certainly, the

optimal compression level depends on the type of files, stored on a

disk/partition, and can only be determined empirically.

For example, we chose the primary hard disk partition with the Windows 98

operating system installed. The partition size was 3.89 GB, actually occupied

space – 683 MB, so the largest part of the partition was free. We chose the

compression level for image creation. The resulting file turned out to be

267 MB. As you can see, the given partitions were actually compressed by

2.6 times, but you shouldn’t highlight it much, as these values are very

rough, because different files are differently compressed.

2.1.7 Creating archive volumes

In the next Image Archive Splitting window you’ll be able to select if the

software should create a single archive file or split it into a number of

volumes. If you set the switch to Automatic, Acronis TrueImage Deluxe will

try to determine settings for certain situations itself. If there’s enough space

on a hard disk that you’ve chosen for locating an image on, the software will

create a single archive file. If there’s not enough space, Acronis TrueImage

Deluxe will prompt you a warning and wait for your actions. You’ll be able to
