I have received the following message.  Can DPM use the 29% allocated disk ? Do I need to take any action on this ?


Status: Active
Volume:  NO_PARAM
Computer: spdb01
Description: Used disk space on replica volume exceeds threshold of 90%.

For more information, open DPM Administrator Console and review the alert details in the Monitoring task area.

You need to look for a resolution message after it.

DPM warns, then tries to expand the disk, then tells you it has succeeded in expanding the disk.

This happens a lot when the installation is new or when you add a lot of data. If it happens all the time you might want to check why your backup volumes are increasing fast.

Where can I see the resolution message ? I can't find it under Protection, Recovery, Reporting or Management tabs...

Can it use the 29% unallocated disk on the DPM ?

If you are getting a-mail alerts it is easier to see the resolution message because they are organised by time.
Otherwise you just need to check the protection groups are all OK.

DPM will use the unallocated space as it needs it.
You can also get disk reports sent by e-mail.

can't receive further email beside the one that I mentioned above.

When I open the protection groups (for SharePoint), it pop out a error (ref DPM01). Is that normal ?

In Modify Disk Allocation window (ref DPM01), Data size refer to the actual database size, and Replica Volume and the Recovery Point Volume are the reserved size for my backup purpose, am I correct ? So, I may need to enlarge the latter two partitions, correct ?

You should have NO errors in your protection groups.
If you are adjusting manually you need to do both volumes, but I prefer to let DPM look after itself.

Last thing to check,

Data size refer to the actual database size, and Replica Volume and the Recovery Point Volume are the reserved size for the backup, and DPM can use the 21% unallocated space for backup if needed. Correct ?


Great Thanks.

At the beginning of the thread you have 29% unallocated space.
Now you have 21% unallocated.

That is nearly 10% of your space used in one day.

I would monitor this very carefully - if your data is growing that fast you will have trouble very soon.

In the above images DPM01 has another problem - not space.
DPM02 is the one you are asking about?

I am not quite clear - all your questions are about space, but you have a path error too.
