1. In the Plan parameters (or Task parameters) section, click Show plan's credentials, comments,

label (or Show task credentials).

2. Click Plan's (Task) credentials.

3. Enter the credentials under which the plan (task) will run.

Scheduled or postponed start

The plan (task) credentials are mandatory. If you skip the credentials step, you will be asked for

credentials after finishing the plan (task) creation.

Why does the program compel me to specify credentials?

A scheduled or postponed task has to run anyway, regardless if any user is logged on or not (for

example, the system is at the Windows "Welcome" screen) or a user other than the task owner is

logged on. It is sufficient that the machine be on (that is, not in standby or hibernate) at the

scheduled task start time. That's why the Acronis scheduler needs the explicitly specified credentials

to be able to start the task.

3.2 User privileges on a managed machine

When managing a machine running Windows, the scope of a user's management rights depends on

the user's privileges on the machine.

Regular users

A regular user, such as a member of the Users group, has the following management rights:

 Perform file-level backup and recovery of the files that the user has permissions to access—but

without using a file-level backup snapshot.

 Create backup plans and tasks and manage them.

 View—but not manage—backup plans and tasks created by other users.

 View the local event log.

Administrative users

A user who has administrative privileges on the machine, such as a member of the Administrators or

Backup Operators group, additionally has the following management rights:

 Back up and recover the entire machine or any data on the machine, with or without using a disk

snapshot.

Members of the Administrators group also can:

 View and manage backup plans and tasks owned by any user on the machine.

3.3 Full, incremental and differential backups

Acronis Backup & Recovery 11 provides the capability to use popular backup schemes, such as

Grandfather-Father-Son and Tower of Hanoi, as well as to create custom backup schemes. All backup

schemes are based on full, incremental and differential backup methods. The term "scheme" in fact

denotes the algorithm of applying these methods plus the algorithm of the archive cleanup.

Comparing backup methods with each other does not make much sense because the methods work

as a team in a backup scheme. Each method should play its specific role according to its advantages.

A competent backup scheme will benefit from the advantages of all backup methods and lessen the
