About Exchange automatic, user-directed, and manual backups
For more information on these backup methods and other administrator-directed activities, see the NetBackup Administrator's Guide, Volume I.
With automatic backups, the NetBackup administrator can schedule the full backups and the incremental backups that occur automatically and unattended. (Incremental backups can be differential incremental backups or cumulative incremental backups.) Automatic backups meet most backup requirements.
You cannot perform an automatic copy backup. To perform a copy backup, run a user-directed backup.
With manual backups, the administrator can perform immediate backups of the files that are associated with any policy, client, or schedule.
The manual backup option can be useful for the following situations:
Testing a configuration
When workstations miss their regular backups
Before installing new software (to preserve the old configuration)
Preserving records before a special event such as when companies split or merge
With the Backup, Archive, and Restore interface, the user can perform backups of Exchange Server, mailboxes, and public folders. A user-directed backup produces a copy backup for Exchange, which is a full backup that does not truncate the transaction logs.
