Number of drives: setting the number of external drives in your backup pool
Accessing the 'number of drives' settings
To access the number of disks settings shown above:
- Click
Jobs in the navigation bar - Select the job to be edited and click
Edit at the bottom of the window. - Click
Destination on the left menu. - Click
Number of disks in your backup pool to expand the section.
The categories listed for the types of disks you can specify (daily, weekly, monthly, etc) depends on what rotation scheme you have selected in the 
Scheduling section of your job.
Selecting a media rotation scheme
- For each backup type listed (daily, weekly, monthly, etc) specify the number of external disks you have available.
- It is recommended that you have at least two drives of each type to allow for rotation of media and offsite archiving. For example, if you had selected the Daily + Weekly + Monthly Rotating Full scheme we would recommend you purchase at least 6 external drives. Having multiple drives will ensure that your data is well protected in the event of disaster and that you have a large archive of backups to restore from.
Specifying the date of the first weekly backup
After setting the number of external hard drives in your backup pool you can specify a date for when your media rotation should commence. This is useful if you have more than one weekly drive as it will determine how the drives are rotated.
For example, if you had two weekly drives and set the start date to 5-Mar-2007, the Week 1 drive would be used on 5-Mar-2007, and the Week 2 drive would be used on 12-Mar-2007. The following week, 19-Mar-2007, would use the Week 1 drive, and you would continue to rotate the two weekly drives for each subsequent week.
- To specify a start date choose a calendar date from the Start the first week of backup on this date drop-down menu.
