Statistical backup sets
DS-Client can generate statistical data on data backup usage and trends before you perform actual backups.
Using Statistical backup sets, you can estimate the initial backup size and the amount of data changes between backups, so that you can determine the duration of the initial backup of baseline data and of subsequent backup sessions.
To perform a statistical backup, you do not need a customer account with a service provider. No backup data is transmitted; only statistical data is gathered and stored in the DS-Client database during a Statistical backup session.
NOTE:  You cannot convert a Statistical backup set to an Online backup set.
To create a statistical backup set
1. Configure the backup set in the New Backup Set Wizard.
2. In the last screen of this wizard, which is Choose the name for this backup set, you can select the backup set type Statistical in the Set Type list.
F1 Help: "Choose the name for this backup set screen"
F1 Help: "Choose the name for this backup set screen (Linux DS-Client)"
The Calculate Transmit Amount check box appears.
3. Select this box to emulate an actual backup transfer process.
During statistical backups, specified backup files will be read from their source and processed for compression/encryption.
4. Click Finish.
5. Allow the backup set to run on schedule or on demand. As a guideline, run the Statistical backup set in your data environment for at least 2 weeks.
The longer the period for which you run a Statistical backup set, the more accurately the trend will be represented.
6. Use the DS-Client Load Summary, Storage Summary, and Report features to view the statistics generated. See “Monitoring DS-Client activities”.
