Overview of resources that support backups

NetWorker provides you with resources that enable you to customize what data is in the backup, when the backup occurs, and how the backup occurs.

The following table summarizes each supporting resource. Many of the resources require planning and configuration on the NetWorker server or on the client itself before the backup occurs.

Table 1. Resource overview
Resource Description Example
Backup levels Defines whether to back up all data on the client, or only data that has changed. Perform a full backup to back up all files, regardless of whether they have changed, or an incremental backup to back up only files that changed since the last backup.
Schedules Defines the backup level to perform on each day. Perform a full backup on Sunday, and an incremental backup on all other days of the week.
Time policies Defines time periods. Use time policies to define save set retention. Save set retention is how long the save set entries are maintained in the media database and client file indexes. Backups for a client are maintained in the database, and can be browsed for recovery for a month.
Directives Specifies resources that contain special instructions that control how the NetWorker server processes files and directories during backup and recovery. For example, encryption and compression. A directive specifies that the backup should skip files with a .tmp extension.
