36 Dell Virtual Storage Manager: Installation Considerations and Local Data Protection | 2079-BP-V-VSM
VSM automatically populates the Name field with the object description, but you can change this if you plan
on applying it to other objects.
2. To apply the same schedule to mulitple types of objects, click Save As Template....
Templates are a useful tool for managing different types of schedules. VSM comes with a few example
templates: Business Hours every hour, Weekly Snapshot, and Gold 2hr. These can be modified or used as
examples for creating new protection schemes.
3. Create a schedule that fits your business needs, and then click OK.
The schedule is placed in the list under Snapshot Schedules. It is immediatly ready to run and can be enabled
or disabled.
4. At this time, more schedules can be applied to this object. In addition, the number of times the snapshot
schedule has been run and the objects inside it can be displayed.
Note: With PS Series firmware version 6.x, snapshot borrowing on the volume can be enabled to allow borrowing
unused snapshot space from another volume or from the free pool space. This allows the retention policy to be met
in the event that the volume does not have sufficient snapshot reserve. For more information on snapshot borrowing,
refer to EqualLogic PS Series Architecture: Snapshot Space Borrowing Overview.
6.3.2 Overlapping datastore schedules
It is important to have an understanding of what VSM is doing in the background during these schedules. Otherwise,
overlapping datastore schedules could occur, preventing the data protection scheme from being achieved. Every object
that has a snapshot is first put into VMware snapshot mode and then the underlying datastore volume on the PS Series
SAN is snapped.
