- Advertisement -

As previously announced, owners of the EX470/475 MediaSmart Servers can now download two new applications for their Servers. The online backup application allows customers to designate specific shared folders on their Server for secure upload to the Amazon S3 service. Doing so provides an additional layer of data protection for the most important photos, documents and other files on your Windows Home Server.

In addition, customers in mixed PC/Mac households can download an application allowing their EX470/475 MediaSmart Servers to backup their Macs running Time Machine.

The most reliable way to get one or both of these updates for EX470/475 owners is as follows:

1) Go to <>

2) On the home page go to the bottom right hand corner where it says “Software & Driver Downloads” and click the link

3) In the text box enter in either EX470 or EX475 and then press the “Enter” key on the keyboard

4) Choose “Server 2003” to locate both packages -customers have the option to download one or both applications

5) Installation instructions are available for both applications by clicking the “view directions” link

  1. Can not get format to work. Keep getting a message to make more space on Server. I have 2TB on my server with 93% free space. How do I make more space on server to allow formating to complete? Have reinstalled Mac OS X to no avail. All updates applied to HP MSS. Any ideas?

    • Bob – Im not sure why it isnt working for you. Have you installed and applied all the updates for WHS? Are you running PP2? How big are you trying to back you Mac Time Backup backup space?

      • Yes – HP MSS Software Version, PP2, and the default of 201, 181, 80, 64, and even tried 1GB. It gets to about 10% complete and then the error message appears. I created the MAC share on the server and it does make a folder called BACKUP, but that as far as it goes. I am able to get all the other connections working to view the home server. I have reinstalled Mac OS X with all current updates/patches also to no avail. This is the one feature I was looking forward to.

        • Bob, I just did a clean install of WHS, applied the updates, installed everything on my Mac, created the Mac share manually and it worked fine. I cant explain why you are having problems. Are you having any other issues on your box?

  2. I'm unable to get that far… 🙁

    I have an EX470 with the latest WHS updates ( The Control Center installs fine on my Mac (10.5.6), I can set my servername/password, size (340GB), and Start the drive. However, when I open Time Machine Preferences and go to select the disk, nothing shows up in the list.

    Any ideas?


    • Ken, once the backup disk has been started in the Preferences window it should automatically have been selected when you enter Time Machine Prefences. The name should say Backup to HP MediaSmart. Have you tried rebooting either your WHS or your Mac, or both? I noticed sometimes when you first set up the backup you need to reboot your Mac and also wait a minute or two depending on the size of your backup drive. I just created a 50GB drive, did the above and it worked fine.

  3. I added the HP Online Backup and over the weekend and uploaded 25 gb of data mainly photos. I previously uploaded the same shares which showed on Amazon as about 35gb of data using the old Jungle Disk Add-In using the same Amazon S3 account. I am not sure how the two accounts mesh the data but it appears from my May 31st bill that I am being billed for 35gb of data. I believe this may be because it is savings different versions of the same files? Does anyone know of a way to clean up the S3 database with the HP Backup software? I know JungleDisk desktop has an option in the software. Also it appears we lost incryption in the HP Online Backup versus the JungleDisk Add-in. Agree?

  4. I've got prolblem with instalation for amazon s3. When i trie to install a message appear HPMEDIASAMRT Server Online Backup require HP Media smart requiere that hp Media smart Server Update 1.3.1 must be installed on the server after i've another message erreor 1603.My sottware version is Thanks fou your response .Patrick

  5. Patrick, sometimes I get an error 1603 if I am impatient and try to install an addin while something else has not finished installing. Wait a bit, then re-install.

  6. No other problems with the MSS. Anybody else getting this error message? It does not make sense. I can access all the other folders created from the Mac, i.e. Music, Photos, etc. from Finder. Err….

  7. I've had all kinds of trouble setting up Time Machine to work with my EX470 (500 GB factory-installed drive + another 1 TB drive). One issue is that Time Machine requires *contiguous* space on the server. Since MSS balances storage across different drives, you have to ensure that there is enough contiguous free space for your Time Machine "disk". The only way I've been able to create any kind of partition so far is to remove the 1 TB drive (MSS copies all existing data on that drive onto the other drive before formatting it), then re-add it. The problem is, even after I re-add it, I can't create a Time Machine partition larger than about 190 GB – anything larger and I get the error message about freeing up more space on the server.

    Even with my 190 GB Time Machine partition successfully created, Time Machine cannot see it on my network for some reason.

    • Alex: Not an option here. I have (4) 500 GB drives in my EX 470 and it would be a waste of time to do the method you metion in your post. I still don't understand why others are not having the same problems. Why did HP release this when it was not ready for prime-time? BTW, I was not able to even create a 1 GB drive. If you find a solution I would really like to know….Bob

  8. This is the most informative Web site I've come across in a while. Thank you for sharing your knowledge. I've recently upgraded my EX470 to the HP v2.5 software and everything works great on my PCs but not my MacBook Pro. The BackupClient runs fine, I enter the HomeServer name and password and it authenticates correctly, but then the UI does becomes unresponsive. You can click on buttons like the Apply button or Backup tab and it depresses but nothing happens. So somewhere between steps 8 and 9 above, things end up not working. Any ideas?

    • Rick – I am having the exact same issue. I enter the credentials, it authenticates, I click Apply, but the Clicking on the Backup tab does nothing.

      Any resolution to this?


  9. Oh and the version of the BackupClient on my Mac appears to be v1.3.0b50. I thought I read somewhere where the client version needed to be 2.5, same as the server software. If this is the case, I'm completely at a loss as to how to get the 2.5 version (but maybe I'm wrong on this point).

  10. Bob – I'm having the exact same problem as you describe. I get the "Backup disk creation failed" error at about 10% when I put any amount of space in the Backup Disk Size field.

    The error dialog tells me to "Make more space available on the server then start the backup disk creation again." However, I have not clue how to go and make more space available when I've got two 500gig drives in my EX475 WHS with a TON of available space.

    I'm guessing there are lots of others out there that are running into this. If anyone finds what I can do next, I would greatly appreciate it. It seems I've run into a brick wall.

  11. Aime, Talked with HP tech support, sent logs, and received an Email that it was a problem with Samba in iMac. They stated they would elevate problem to see if a fix is possible. To date, still no reply. Oh well, I manually copy all my important files from my iMac to my HP MSS. Pain in the butt, but best solution I have found. If you get any info, please pass-on….Bob

  12. Bob – had the same issue, after setting up the software on mac it wouldn;t format past 2%, restarted the server and it started fine, did you try to remote in to the server and do all windows updates? restart after, and run the mac software again.

    By the way did you create the MAC share on the server using a PC?


  13. Is there anyway to get this installed on a non HP home server?

    I get "media smart server update 1.3.1 must be installed"

    • Sean – not that I am aware of, but thats not to say that you might not be able to hack it, Ive just not seen anyone who has been able to do it.

      Sorry – Andrew

  14. I've been looking for a solution to the problem described in this thread. I'm having the same issues as Bob. Did anyone ever find a solution that worked???

  15. Same problem on 2011 MacBook Pro and WHS Mediasmart.
    The drive gets created fine, but after clicking on Start and waiting for 2 minutes it fails, inviting me to install “it” (?) manually.
