About Schedule Manager
The Schedule Manager (nvsched) runs on the NetVault Backup Server and performs the following functions: • It manages the job schedules and queues. The Schedule Manager initiates the Job Manager to launch a
job instance, and schedules the next instance for recurring jobs. The actual job execution is carried out by the Job Manager.
• It manages the Scheduler database. The Schedule Manager updates the Job Status page and provides job scheduling data to the Reporting utility.

Process Table This setting controls the amount of shared memory allocated to the Process Table that maintains the details of all current NetVault Backup processes. The default value for this option is 16384KB on Windows and 500KB on Linux and UNIX.
On NetVault Backup machines running a number for concurrent processes, you can increase the amount of shared memory for the Process Table to get optimum performance. To increase the shared memory, type or select a new value. The shared memory is allocated in KB.
NOTE: On Windows, the shared memory is allocated dynamically. On Linux and UNIX, the shared memory for the process table is allocated from the shared memory pool. To increase the shared memory for the process table on these platforms, you must first increase the overall shared memory pool. This can be done by configuring the shmmax variable in the system configuration file. For more information about increasing the shared memory pool, consult the relevant O/S documentation.

Default backup job priority
Default restore job priority
Default report job priority
The Schedule Manager assigns a priority level for each job type, which is applied globally to all backup, restore, and report jobs. This setting is used to prioritize resource allocation when two or more jobs are scheduled to run at the same time.
The default priority levels are: • Backup job – 30 • Restore job – 20 • Report job – 50
To change the priority level settings globally for all jobs, configure the following options:
• Default backup job priority • Default restore job priority • Default report job priority
Type or select a value from 1 through 100. 1 denotes highest priority, while 100 denotes lowest priority. A job with a priority level of zero (0) runs as a background task.
To override the priority setting for an individual job, configure the Job Priority option in the Schedule Set. For more information, see Creating a Schedule Set, Job retry and priority settings for Schedule Set.
