A Backup Definition contains the data needed to perform a backup on a set of computers. Each definition contains settings for the following information:
- A list of computers which should be backed up.
- A set of rules describing which partitions and disks to backup on each computer
- A set of options and settings controlling how the backup files should be created and stored.
Backup Definitions contain all the information on how and what to backup. A Backup Definition can be run manually to perform a single backup of each computer or used to schedule regular backups into a Repository
Creating a Backup Definition
The 'Backup Definition' section option in the Management Console contains the list of existing backup plans.
If there are no Backup Definitions created, a quick help page is shown instead:
Clicking on 'New Definition' will open the Backup Definition wizard. To create a Backup Definition, a name must be entered for the Backup Definition in the top of the wizard and all wizard steps completed. An optional description may also be entered. The steps of the wizard are:
Step 1 - Computers
This stage lists available computers to be part of the Backup Definition. Once the computers required have been selected, press 'Next' to advance to the next step.
Step 2 - Disks
In this stage, rules are defined to determine which disks and partitions will be backed up as part of this Backup Definition. A set of rules are available on the left hand side of the screen. To use a rule, select it and press the '>' button to move it to the right have side of the list. Some rules have additional configuration such as a volume label or drive letter to match. In this case, a dialog box will pop up when adding the rule as seen below:
Once rules have been added, they are listed in the right hand pane of the interface. If a rule has additional configuration, it can be reconfigured by pressing the pencil icon on the right of the rule name. A rule may be removed by clicking it to select and clicking the '<' button.
The area below the rule lists shows the disks and partitions of the selected computers and whether they match the selected rules. In the example below, a single partition on the computer shown matches:
The disk matching information can be filtered to show matching partitions/disks or non-matching ones only.This can help identify any gaps in rules.
For simple operation, there is an 'All Disks' rule which will match everything on a computer.
Once rules are configured, press next to move to the next step.
Step 3 - Options
In step 3, options for how the backup files are created are set.
|Compression||The level of compression to use in any backup files created when using this Backup Definition. The default level is 'Medium'.|
|Encryption||The type of encryption to use on any backup files created from this Backup Definition. If AES encryption is used, a password must be entered using the 'Set Password' button.|
|Verification||If this option is selected, backup files will be reread and verified immediately after creation.|
|Comment||If a comment is entered here it will be saved as part of any backup files created and be visible to any restore tools.|
Once the options are set appropriately, press finish to complete the wizard and save the Backup Definition. If there are any errors or issues with saving the Backup Definition, the wizard will not close and an error message will be displayed:
Once the error message has been corrected, the issue can be fixed in the wizard. If appropriate any affected fields will be highlighted in red.
Backup Definition Operations
Once Backup Definitions have been created, they are shown in a list as below:
The selected Backup Definition can be changed by clicking on the list of names in the left-hand column. Once a Backup Definition has been selected, the configuration of that Definition is shown. Several operations can be performed on this Definition.
Deleting a Backup Definition
Clicking the 'Delete' button to the right of the definition name will delete the selected Backup Definition.
Copying a Backup Definition
Clicking the 'Copy' button to the right of the definition name will copy the selected Backup Definition to a new Definition which can then be edited. This is useful for creating multiple Definitions with only minor differences. The new Definition must be given a new name:
Editing a Backup Definition
Editing a Backup Definition is possible by clicking any of the Edit buttons in the page. Each button will open the Backup Definition wizard at the appropriate wizard step. This is the same process used in creating a Backup Definition except the wizard will be pre-populated with data from the selected Definition. When editing a Backup Definition the 'Finish' button may be pressed at any stage and not just the final one.
Running a Backup Definition Manually
To run a Backup Definition on a one-off basis, the 'Run Now' button can be clicked. This opens a wizard to allow the computers to backup, type of backup and backup destination to be chosen:
The first stage of the wizard allows computers to be selected. If only a subset of computers in the Backup Definition are to be backed up, they can be selected here.
The second stage of the wizard allows a Repository to be selected to store the backup files made. This must be a Repository which has been created in the Repositories section of the Management Console. More information is available here.
Additionally, the type of backup should be selected. This may be Full, Differential or Incremental. Once these have been selected, pressing 'Finish' will perform the backup on the selected computers.
If a Differential or Incremental backup is selected without a corresponding Full backup in the Repository to base the Differential or Incremental backup on, the computer will perform a Full backup instead.
Running Backups Automatically on a Schedule
To perform automated backups according to a schedule, The Backup Definition can be scheduled to run in a Repository according to a Schedule. More information is available here.
