Backup methods in Backup Exec
When you create a backup definition, you must select backup methods for each backup job. The backup method determines what data Backup Exec backs up. The standard backup methods are full, differential, and incremental. However, you can also select specific types of backup methods for some agents and types of data.
Each backup definition must contain one backup job that uses the full backup method. This initial full backup job establishes a baseline by backing up all of the data that you selected. Then, you can add additional differential or incremental backup jobs to the backup definition. You can select to use data-specific backup methods instead of the standard backup methods by selecting the appropriate backup method on the options page for that agent.
This topic includes the following information:
Backup method advantages and disadvantages
Backup methods for specific types of data
Full backups include all of the data that was selected for backup. Backup Exec detects that the server was backed up.
Note:
You should perform a full backup of your server to establish a baseline for disaster recovery.
Duplicate backups, which include all selected data, are a type of full backup. Duplicate backups do not affect any tape media rotation strategy because the archive bit is not reset.
It is recommended that you always run full backups before and after you upgrade, update, or modify any backup sources. This recommendation applies to any significant operating system and application configuration or modifications.
Table: Backup sources and scenarios for which a full backup is recommended
Backup source | Scenarios for which a full backup is recommended |
---|---|
Operating system | You should run a full backup when you:
|
Applications | You should run a full backup when you:
|
Backup Exec | You should run a full backup when you:
|
Running full backups before and after each of these scenarios helps to ensure that you can restore back to the previous configuration, if necessary.
Differential backups include all files that have changed since the last full backup or incremental backup. The difference between differential and incremental backups is that differential backups are cumulative. After a differential backup, each subsequent differential backup backs up the same files as the previous differential backup. It also backs up as any new files or changed files dating back to the last full backup or incremental backup.
Note:
In a backup definition that includes a differential task, all of the backup tasks must use storage devices that the same Backup Exec server can access.
By default, Backup Exec uses the Windows Change Journal to determine if files were previously backed up. You can also configure Backup Exec to use a file's modified time or archive bit to determine if the file was backed up.
Note:
You cannot use Backup Exec catalogs to determine if files were backed up for any differential backups.
See Configuring file and folder options for backup jobs.
Differential backups allow much easier restoration of an entire device than incremental backups since fewer backups are required. Using fewer media also decreases the risk of having a restore job fail because of media errors.
Incremental backups include only the files that have changed since the last full or incremental backup. The difference between incremental and differential backups is that incremental backups are not cumulative. Each incremental backup creates a baseline. After the incremental backup, the subsequent incremental backup or differential backup backs up only any new files or changed files dating back to the baseline.
Note:
In a backup definition that includes an incremental task, all of the backup tasks must use storage devices that the same Backup Exec server can access.
By default, Backup Exec uses the Windows Change Journal to determine if files were previously backed up. You can also configure Backup Exec to use a file's modified time, archive bit, or the Backup Exec catalogs to determine if the file was backed up.
See Configuring file and folder options for backup jobs.
Incremental backups take much less time than full or differential backups to complete. They also require less storage space for backed up data since only any files that have changed since the last backup are backed up.
Each backup method has advantages and disadvantages.

Consider the following backup strategy scenario:
You want to implement a backup strategy for the office file server. All backup strategies begin with a full backup (the backup of an entire server using the full backup method). So you create and submit a full backup job to run at the end of the day on Friday.
Most files on the server, such as operating system files and application files seldom change. Therefore, you decide that you can save time and storage by using incremental backups or differential backups. You opt to use incremental backups. You schedule a job to run at the end of each day, Monday through Thursday, with the incremental backup method.
On Friday, your backup sets contain all of the data on the file server. Backup Exec changes all of the files' statuses to backed up. At the end of the day on Monday, the incremental job runs and only the files that were created or changed are backed up. When the incremental job completes, Backup Exec turns off the archive bit, showing that the files have been backed up. On Tuesday through Thursday, the same events happen.
If your file server then crashed on Thursday, you would restore each backup in the order in which it was created. You would begin with Friday's backup and proceed through Wednesday's backup.
If you had decided to perform differential backups on Monday through Thursday, you would have only needed Friday's and Wednesday's backup sets. Friday's backup sets would have included all of the data from the original backup. Wednesday's backup sets would have included every file that had been created or changed since Friday's backup.
Agents and features may have specific types of backup methods.
By default, each backup definition contains a backup job that limits the available backup method to the initial full backup for most data types. You can configure additional backup jobs that contain special backup methods for specific types of data. You can name the job templates for those backup jobs so that they have additional meaning to your organization's overall backup strategy.
See Configuring backup methods for backup jobs.
When you create a backup definition that contains more than one backup method for multiple data types, it is called a mixed backup in the Job Monitor.
