Backups and archives - UNIX clients
For UNIX clients, NetBackup supports scheduled, immediate manual, and user-directed backups of both files and raw partitions. User-directed archives of files are also supported; raw partition archives are not supported. When the operations start, they are all similar to the extent that the same daemons and programs execute on the server.
Each type of backup is started differently as follows:
Scheduled backups begin when the nbpem service detects that a job is due. It checks the policy configurations for the scheduled client backups that are due.
Immediate manual backups begin if the administrator chooses this option in the NetBackup Administration Console or runs the bpbackup -i command. This action causes bprd to contact nbpem, which then processes the policy, client, and schedule that the administrator selects.
User-directed backups or archives begin when a user on a client starts a backup or archive through the user interface on the client. The user can also enter the bpbackup or bparchive command on the command line. This action invokes the client's bpbackup or bparchive program, which sends a request to the request daemon bprd on the primary server. When bprd receives the user request it contacts nbpem, which checks the policy configurations for schedules. By default nbpem chooses the first user-directed schedule that it finds in a policy that includes the requesting client.
For user-directed backups or archives, it is also possible to specify a policy and schedule. A description is available of the UNIX BPBACKUP_POLICY and BPBACKUP_SCHED options in bp.conf and the Windows equivalents.
