Backup and Restore Functional Description NetBackup 4.5 Troubleshooting Guide for Windows Backup and Archive Processes The backup and archive processes vary depending on the type of client. The following explains the basic variations. There is also a description of how NetBackup operates when backing up its databases. 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 is also supported (you cannot archive raw partitions). Once started, these operations are all similar to the extent that the same daemons and programs execute on the server (see Figure 7). Each type, however, is started differently. ◆ Scheduled backup operations begin when the NetBackup request daemon, bprd, activates the scheduler, bpsched. This occurs at intervals determined by the Wakeup Interval global attribute. Once activated, the scheduler checks the policy configurations for scheduled client backups that are due. ◆ Immediate manual backups begin if the administrator chooses the manual backup option in the NetBackup administrator interface. This causes bprd to start bpsched, which then processes the policy, client, and schedule selected by the administrator. ◆ User-directed backups or archives begin when a user on a client starts a backup or archive through user interface on the client (or the bpbackup or bparchive commands). This invokes the client’s bpbackup or bparchive program, which sends a request to the request daemon bprd on the master server. When bprd receives the user request, it starts bpsched, which checks the policy configurations for schedules and by default chooses the first user-directed schedule that it finds in a policy that includes the requesting client. It is also possible to specify a policy and schedule by using the NetBackup configuration options, BPBACKUP_POLICY and BPBACKUP_SCHED, on the client. The bpbackup and bparchive programs execute with the same permissions as the user. If you can read and write files (delete in the case of an archive), they can too. 422 NetBackup Troubleshooting Guide - Windows NT/2000 NetBackup 4.5 Troubleshooting Guide for Windows
