User`s guide

The optimal data compression level depends on the type of files stored in the backup. For example,

even maximum compression will not significantly reduce the backup size, if the backup contains

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

Operation priority

Changing the priority of a backup or recovery process can make it run faster or slower (depending on

whether you raise or lower the priority), but it can also adversely affect the performance of other

running programs. The priority of any process running in a system, determines the amount of CPU

usage and system resources allocated to that process. Decreasing the operation priority will free

more resources for other CPU tasks. Increasing backup or recovery priority may speed up the process

by taking resources from the other currently running processes. The effect will depend on total CPU

usage and other factors.

You can set up the operation priority:

 Low (enabled by default) - the backup or recovery process will run slower, but the performance

of other programs will be increased.

 Normal - the backup or recovery process will have the equal priority with other processes.

 High - the backup or recovery process will run faster, but the performance of other programs will

be reduced. Be aware that selecting this option may result in 100% CPU usage by Acronis True

Image Home 2011 Netbook Edition.

Network connection speed

If you frequently back up data to network drives or FTP, think of limiting the network bandwidth used

by Acronis True Image Home 2011 Netbook Edition.

You can specify the network backup data transfer speed by choosing one of the following:

 Transferring speed stated as a percent of the highest possible speed - drag the slider to set the

desired limit for transferring backup data.

 Transferring speed stated in kilobytes per second - enter the bandwidth limit for transferring

backup data in kilobytes per second.

3.10.14 Notifications for backup operation

Sometimes a backup or recovery procedure can last an hour or longer. Acronis True Image Home

2011 Netbook Edition can notify you when it is finished via e-mail. The program can also duplicate

messages issued during the operation or send you the full operation log after operation completion.

By default all notifications are disabled.

Free disk space threshold

You may want to be notified when the free space on the backup storage becomes less than the

specified threshold value. If after starting a backup Acronis True Image Home 2011 Netbook Edition

finds out that the free space in the selected backup location is already less than the specified value,

the program will not begin the actual backup process and will immediately inform you by displaying

an appropriate message. The message offers you three choices - to ignore it and proceed with the

backup, to browse for another location for the backup or to cancel the backup.
