Operation Manual

Please do not try to execute interactive commands, i.e. commands that require user input

(for example, “pause”). These are not supported.

Unchecking the Do not perform operations until the commands execution is

complete box, checked by default, will permit the backup process to run concurrently with

your commands execution.

5.3.4 Compression level

The preset is Normal.

If you select None, the data will be copied without any compression, which may significantly

increase the backup file size. However, if you select Maximum compression, the backup will

take longer to create.

The optimal data compression level depends on the type of files stored in the archive. For

example, even maximum compression will not significantly reduce the archive size if the

archive contains essentially compressed files, like .jpg, .pdf or .mp3.

Generally, it is recommended that you use the default Normal compression level. You might

want to select Maximum compression for removable media to reduce the number of blank

disks required.

5.3.5 Backup priority

The preset is Low.

The priority of any process running in a system determines the amount of CPU usage and

system resources allocated to that process. Decreasing the backup priority will free more

resources for other CPU tasks. Increasing the backup priority may speed up the backup

process as it takes resources from other currently running processes. The effect will depend

on total CPU usage and other factors.

5.3.6 Archive-splitting

Sizeable backups can be split into several files that together make the original backup. A

backup file can be split for burning to removable media or saving on an FTP server (data

recovery directly from an FTP server requires the archive to be split into files of no more

than 2GB). A backup destined for a backup location or Acronis Secure Zone cannot be split.

The preset is Automatic. With this setting, Acronis True Image Home will act as follows.

When backing up to the hard disk:

If the selected disk has enough space and its file system

allows the estimated file size, the program will create a single archive file.

If the storage disk has enough space, but its file system does not allow the estimated file

size, Acronis True Image Home will automatically split the backup into several files.

FAT16 and FAT32 file systems have a 4GB file size limit. But a hard drive’s capacity can be

as much as 2TB. Therefore, an archive file might easily exceed this limit, if you are going to

back up the entire disk.

If you do not have enough space to store the image on your hard disk, the program will

warn you and wait for your decision as to how you plan to fix the problem. You can try to

free some additional space and continue or click Back and select another disk.

When backing up to a diskette, CD-R/RW or DVD+R/RW:

Acronis True Image Home will ask

you to insert a new disk when the previous one is full.
