Factors that affect backup time
The amount of time that NetBackup requires to complete a backup is an important factor in setting up schedules. The importance of time is particularly true for the sites that handle large amounts of data. For example, the total backup time can exceed the time that is allotted to complete backups and interfere with normal network operations. Longer backup times also increase the possibility of a problem that disrupts the backup. The time to back up files can also give an indication of how long it may take to recover the files.
