24 Copyright © Acronis, Inc., 2000-2009Managing a plan (task) owned by another userHaving Administrator privileges on the machine, a user can modify tasks and local backup plansowned by any user registered in the operating system.When a user opens a plan or task for editing, which is owned by another user, all passwords set in thetask are cleared. This prevents the "modify settings, leave passwords" trick. The program displays awarning each time you are trying to edit a plan (task) last modified by another user. On seeing thewarning, you have two options:• Click Cancel and create your own plan or task. The original task will remain intact.• Continue editing. You will have to enter all credentials required for the plan or task execution.Archive ownerAn archive owner is the user who saved the archive to the destination. To be more precise, this is theuser whose account was specified when creating the backup plan in the Where to back up step. Bydefault, the plan's credentials are used.Plan's credentials and task credentialsAny task running on a machine runs on behalf of a user. When creating a plan or a task, you have theoption to explicitly specify an account under which the plan or the task will run. Your choice dependson whether the plan or task is intended for manual start or for executing on schedule.Manual startYou can skip the Plan's (Task) credentials step. Every time you start the task, the task will run underthe credentials with which you are currently logged on. Any person that has administrative privilegeson the machine can also start the task. The task will run under this person's credentials.The task will always run under the same credentials, regardless of the user who actually starts thetask, if you specify the task credentials explicitly. To do so, on the plan (task) creation page:1. Select the Advanced view check box.2. Select General -> Plan's (Task) credentials -> Change.3. Enter the credentials under which the plan (task) will run.Scheduled or postponed startThe plan (task) credentials are mandatory. If you skip the credentials step, you will be asked forcredentials 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 (forexample, the system is at the Windows "Welcome" screen) or a user other than the task owner islogged on. It is sufficient that the machine be on (that is, not in standby or hibernate) at thescheduled task start time. That's why the Acronis scheduler needs the explicitly specified credentialsto be able to start the task.
