DPM2010: Disconnected clients feedback
Simon
the ability to protect clients (even notebooks) is great. I'm looking
forward to implement this soon!
During my tests I found the following problems:
- Backups slow down the protected client. Reducing the priority of DPMRA.exe
to "Low" and issuing low-priority IO could solve this problem. (also applies
to protected servers)
- There should be an easy way to postpone backup by 1/3/5 hours from the
client.
- There's no feedback about the backup process. The only status I see on my
client is "Connecting to DPM Server...". I'd like to know when the sync will
be done.
- I couldn't find out how to reduce the size of the "Recovery point volume"
and increase the size of the "Replica volume".
- I'd like to do bare metal recovery (possibly to different hardware).
Similar to what is possible with Windows Home Server.
DPM 2010 is a joy to use. Thanks!

[Venkat] Can you mention when exactly are you observing this, is this during
first few minutes of backup? After a successful first backup, the next
backups should be very light weight.

[Venkat] thanks for the feedback. I shall forward this to the team.

[venkat] It means client is failing to connect to DPM. There is a known
issue in beta. can you exit the client UI in notification area in the right
corner of desktop & relaunch & try again? If the issue persists, ping us.

[venkat] you can increase replica volume by increasing per laptop
allocation. the shrink option is not present in beta build, it will be
available in RC.

[venkat] wait for RC.

This is during the initial sync. The clients are still in this state because
1) Initial sync starts
2) DPM runs out of space, increases space (auto grow)
3) Go back to 1
I noticed this problem on a notebook with a not-so-fast harddisk. DPM brings
the system to a crawl (client runs Windows 7). The first few minutes are very
bad, then it gets a bit better.

I tried that. Current status shows "Connecting to DPM Server...", the
tooltip "Synchronizing..." after the third restart. Before that the tooltip
said "Unable to connect" (or something like that).

Great!
Enjoy your weekend!

or LAN. If we had the facility to sync over the internet this could kill
solutions like I folder for good.

disable "ScheduledDPMClientBackup" schedule. Please remember to enable it ,
else your backups wont happen.
We will discuss implementing this feature in the product.
Thanks

After some more experience I noticed that this problem also occurs when
there's a lot of new data on the client. And, yes, the backups are otherwise
very fast, but they still have a some impact on client performance. I usually
stop my work and wait until the sync is over.
An example: I run a notebook, install Office 2010 and Visual Studio 2010.
The next sync takes some minutes - during that time the computer is barely
useable. It took minutes until Resource Monitor showed up and half a minute
to open a command prompt. Disk activity was at a constant 100%, almost
exclusively reading.
I'm not sure I want to deploy this in a production environment...
