2.3. User privileges on a managed machine

When managing a machine running Linux, the user has or obtains the root privileges, and so can:

• Back up and recover any data or the entire machine, having full control over all Acronis Backup &

Recovery 10 agent operations and log files on the machine.

• Manage local backup plans and tasks owned by any user registered in the operating system.

To avoid routine logging on to the system as root, the root user can log on with the ordinary user

credentials and then switch user as required.

2.4. Owners and credentials

This section explains the concept of owner and the meaning of a backup plan's (or task's) credentials.

Plan (task) owner

A local backup plan owner is the user who created or last modified the plan.

A centralized backup plan owner is the management server administrator who created or last

modified the centralized policy that spawned the plan.

Tasks, belonging to a backup plan, either local or centralized, are owned by the backup plan owner.

Tasks that do not belong to a backup plan, such as the recovery task, are owned by the user who has

created or last modified the task.

Managing a plan (task) owned by another user

Having Administrator privileges on the machine, a user can modify tasks and local backup plans

owned 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 the

task are cleared. This prevents the "modify settings, leave passwords" trick. The program displays a

warning each time you are trying to edit a plan (task) last modified by another user. On seeing the

warning, 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.
