 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 CD-R/RW, DVD-R/RW, DVD+R/RW, BD-R/RE:

 Acronis True Image Home 2011 Netbook Edition will ask you to insert a new disk when the

previous one is full.

Alternatively, you may select the desired file size from the drop-down list. The backup will then be

split into multiple files of the specified size. That comes in handy when backing up to a hard disk with

the view to burning the backup to CD-R/RW, DVD-R/RW, DVD+R/RW or BD-R/RE later on.

Creating images directly on CD-R/RW, DVD-R/RW, DVD+R/RW, BD-R/RE might take considerably more time

than it would on a hard disk.

3.10.6 Backup validation option

You can specify the additional validation setting: Validate backup when it is created.

When this option is enabled, the program will check the integrity of the recently created or

supplemented backup version immediately after backup. When setting up a backup of critical data or

a disk/partition backup, we strongly recommend that you enable this option in order to ensure that

the backup can be used to recover the lost data.

Regular validation

You can also schedule validation of your backups to ensure that they remain "healthy". By default

regular validation is turned on with the following settings:

 Frequency: once a month

 Day: the date when the backup was started

 Time: the moment of backup start plus 15 minutes

 Advanced settings: the Run the validation only when the computer is idle check box is selected

Example: You start a backup operation on July 15, at 12.00. The backup version is created at 12.05.

Its validation will run at 12.15 if your computer is in the "screen saver" state at the moment. If not,

then the validation will not run. In a month, August 15, at 12.15, the validation will start again. As

before, your computer must be in the "screen saver" state. The same will occur on September 15,

and so on.

You can change the default settings and specify your own schedule. This may be useful if you set a

custom backup scheme with incremental backups. For example, you may want to schedule validation

of all backup versions (the initial full backup version and subsequent incremental backup versions)

once a week.

For more information see Scheduling (p. 120).
