Backup DS- Series VM vhd's from Premium storage to Standard

Hi ,
How to move DS- Series VMs from Premium storage to Standard storage & create D-Series VMs using backed up vhd ?

Hi Dinesh;
As DS Series VM uses a different computing architecture compared to a D series VM one cannot save the VHD file and convert it back to a D series VM.

Disk Performance of DS-Series VMs (Premium Storage)

We're running performance tests on two new Standard DS13 (8 Core, 56 GB) VMs (both using the latest/default Windows 2012 R2 image) backed by Premium Storage and have hit a wall with step 1 in testing the local SSD performance.
We understand 25% of the 400GB local SSD for these VMs is made available as temporary storage and the other 75% is used for Premium Storage caching:
http://azure.microsoft.com/blog/2014/12/11/new-premium-storage-backed-virtual-machines/
On the remaining 25%, we expect to see performance along these lines:

Any guidance would be appreciated:
Why is the local SSD storage throttled at 500 IOPS and 1-4 MB/s throughput?
How do we achieve 200MB/s on writes as we see with reads on P30s, what's the test to run?
Can you publish I/O benchmarks that we can run to validate our setup?

Error registering DS-Series VM with OS disk on Premium Storage

Hi, are there any known issues in relation to backing up DS-series VMs that are created with an OS disk on premium storage? I've
tried testing with two different subscriptions and two different premium storage accounts and get an error when trying to register a DS-series VM which has an OS disk on a premium storage account.
ERROR DETAILS
Microsoft Azure Backup encountered an internal error.
Wait for a few minutes and then try the operation again. If the issue persists, contact Microsoft Support.
I've just created a DS-series VM on a standard storage account and registered it successfully. I haven't tried attaching a premium disk and backing
up yet however.

Yes, VMs with disks on premium storage are not supported right now for Azure Backup. We will be updating our documentation shortly to reflect that limitation.
We will also update the forum when that support is available

I have about 130 gigs of movies on my iTunes and was wondering if I can just put them on my backup hard drive and remove them from my main computer to free up the space

I have about 130 gigs of movies on my iTunes and was wondering if I can just put them on my backup hard drive and remove them from my main computer to free up the space.

I haven't done this with an external drive, but I would imagine it works the same way as if you have multiple internal drives. Also hopefully it works with less headache in OSX than in windows.
Anyway, move all your music over to your external, and then go into itunes -> preferences -> advanced -> iTunes media folder location. Navigate to your drive, and pick the folder you want. Ensure that your folders are set up like they are in your ~/Music/iTunes folder, or wherever your iTunes is currently pointing. Then quit and restart itunes. If your music doesn't show up, try dragging your music folder from your external onto itunes, and it will hopefully update your library.xml.
As far as Jerry's problem goes, you could try adding another music folder to your library.xml, but I really have no idea whether this will work or not. If you want to give it a try (can't promise you won't corrupt your library.xml, so make a copy beforehand) you can find the music folder xml element right near the top of the xml file (open it with textedit/textmate/whatever text editor you want (NOT WORD)). Curious to know if this works, and if it doesn't I have other ideas so let me know.

I cannot see my iPhone backup when I click on "restore from backup"

Hi there, I just upgraded my iPhone to iOS 5.1. Before I began I backed up my iPhone within iTunes. I checked that the backup was successful by checking the folder and files existed in "%AppData%\Apple Computer\MobileSync\Backup" - which they did. After the upgrade which iTunes told me was successful I have my Contacts and Photos but have lost my ringtones, music and texts. I'm particularly bothered by losing my texts because I had historical texts from my Mum who has passed away recently. I went back into iTunes, right clicked on my device and selected "restore from backup" but in the list of backups it does not list my backup - just a really old one from my son's phone a number of months ago.
Can anyone help with this? Is there a way to tell iTunes that the backup exists and to point it there? (sorry, I'm a Windows user only)
Also, another issue while I'm here and may be related (not sure). I'm unable to synch my phone with iTunes as it says it's already synched with another computer (which it was but it died a horrible death and has since left this world). So currently the only way I can update music, ringtones etc is through a 3rd party free app called Copy TransManager. Anyone know a way out of that problem?
This Kiwi would appreciated any wisdom, assistance, help you can offer on these two points. In order of priority ... I can manage with the non-sync weirdness as I've found a work around .... getting my backup to work so I can get my texts is of upmost importance to me. Thank you.

Since you can no longer backup to disk, how to restore from external drive without losing all ratings and playlists

since you can no longer backup to disk, how to restore from external drive without losing all ratings and playlists?

My own opinion is that you should install the later appropriate version of Silverkeeper. That said, I would in fact recommend if you can wait a few days for an answer, that you email the La Cie Silverkeeper backup team via the email link on the site at http://www.lacie.com/silverkeeper/
They are careful to say they are not officially providing a backup service, but when I emailed them with a query regarding usage about a year ago after downloading Silverkeeper for myself, I got a reply within a couple of days that cleared up my question.

Server 2008 R2 Windows Server Backup. "Error in backup of Hyper-V.vhd during read: Error [0x80070001] Incorrect function.

Hello,
We are currently using Windows Server Backup to backup three Hyper-V guests running on a Windows 2008 R2 host. Two guests are running Server 2008 R2 and one is running Windows 7. I have the backups going to a dedicated external disk drive.
WSB backs up the two 2008 R2 Hyper-V guests just fine. However, when attempting to backup the Windows 7 Hyper-V guest, I receive the following error:
Error in backup of <Windows 7.vhd> during read: Error [0x80070001] Incorrect function.
I ran a "vssadmin list writers" and all the VSS writers showed "Stable" with no errors. I have plenty of space on the external drive as well. I've read this article:
https://support.microsoft.com/kb/973455?wa=wsignin1.0#workaroundissue12 except that doesn't seem to be what I'm experiencing here.
Anyone have any suggestions?

Hi,
As the other 2 guests could be backed up correctly, the issue should not be the Windows Server Backup feature.
First please refer to this article:

How can I make a backup to an external hard drive from iPhoto if it won't open?

how can I make a backup to an external hard drive from iPhoto if it won't open? I just wan't to make a backup to my pictures not my entire computer so how does Time Machine work on that?

you could also clone the drive or volume, or just some of the user folders. look for carbon copy cloner, then enable the "use checksum to insure file integrity."
you can have multiple iPhoto Library catalogues in different locations.
Continue to use TimeMachine and make sure it has 350% or more capacity than your system and data.

I have an iPhone 4S that is a replacement of a defective 4s and it shows over 3Gb of data backed up in the cloud from my old 4s. How can I find out what is in this backup? It is preventing me from backing up my new 4s to the cloud due to the amt of data.

I have an iPhone 4S that is a replacement of a defective 4s. When I activated the newer phone, I believe I transferred over everything except pictures (had multiple failures trying to backup and restore). Now the phone shows over 3Gb of data backed up in the cloud from my old 4s. How can I find out what is in this backup? It is preventing me from backing up my new 4s to the cloud due to the amt of data. It may be duplicated info that I don't need or I may want to archive the backup or parts of it like pictures.

You can not access the backup directly.
Did you restore your replacement from this backup?
If so then you already have everything in the backup on your device.
If not, you can wipe the device and restore from this backup:
Settings > General > Reset > Erase All Content & Settings
What is it you are worried about losing that isn't already on your current device?

I got new iphone and when i connect it to my pc, it lost all my current data and replaced it with the backup on my computer, which is from april. so i have lost all my calendar information and schedule. does anyone know how i can reverse this?

Every backup replaces the old one, so, unless you included the backup folder in your computer backup routine, you can't get back your calendar info.
The only time iTunes will not replace a backup is, when you use it to restore from, this one will stay in the backup list in iTunes.

How do I create a series of text frames from a list of files?

And I'm back again.
This time, I'm wondering how I can use JavaScript to place a series of text frames from a list of files, preferably with the ability to specify criteria before running the script.
Here's the details: I work for a newspaper and I lay out stories for the pages (in addition to the other part of my job, laying out ad spaces, as detailed in a previous thread, for which I requested another script, thanks Andreas and Jongware ). The file names for the stories are labeled for the section they go in, like L- for Life, C- for Comment, S- for Sports, etc.
I'd like to create a script that asks for a criteria in a text box (where I can type L-, C-, S- or whatever else I need) and then places all of the stories, in a specified directory, whose file names match what was typed in the box, one text frame for each.
I can't rightly tell if this is a simpler or more difficult script to write out, but I plan on putting research into it as usual so I can develop it myself. However, I figured it would be more efficient to ask first, then research, so that while I'm researching, I can refer to the opinions of my fellow forumites, and/or the mods.
Thanks again for any assistance offered.

Upgrading to 4.0.1 changes license from Premium to Standard

I'm running a volume licensed version of Flash Builder 4 part of the CS5 Web Premium suite. After updating to Flash Builder 4.0.1, it now loads as Flash Builder Standard. Is that just the title that is showing incorrectly on the start screen and about page, or have I somehow magically been downgraded from Premium to Standard?
Thanks.

I'm definitely downgraded to standard. When I go to Flex Unit it tells me I need a Premium license.
So far this has happened on 2 computers. One (win XP sp3) with Flash Builder pre-installed and then CS 5 installed and one (Windows 7 Home Premium 64-bit) with no Abode products installed until all of CS 5 was installed. It can`t just be you and I who have experienced this.

Import .VHD Files from Virtual Iron or Xen Server

Hi,
I have some .vhd Files from the XEN Based Virtual Iron Server here. I copied them to the OVM Server and try to start but the only thing i got was a "Booting from Harddisk" at the console. Do i have to convert them. Do you know how?
Thank you.

Okay, seems that one of the .vhd was broken. i did a new export in VI and import in OVM, now it works.

Copy .vhd from secondary storage account to another storage account in primary location (RA-GRS) enabled using power shell scripts

All,
Hope you are doing great. I have a storage account which is RA-GRS enabled. Which has couple of (IaaS based vms) .vhd. I have taken few snapshots on the VMs too.
Queries:
1. How do I copy the .vhds from secondary storage account to different account in primary location?
2. If I copy the .vhds. Does it copy all the snapshots which was taken?
Please advice. Many thanks!
Regards,
Swamy

Hi Jambor,
Hope you are doing great. I am facing a problem.
1. Imagine I have a storage account with RA-GRS enabled. US East (Primary) and US West (Secondary)
2. I have created a VM in US East and taken couple of snapshots. Which means the .vhd and its snapshot will be replicated in the Secondary location.
3. Assume that Primary site is down. Not I want to read the .vhd and its snapshot from secondary and create VM in Primary location.
4. I tried the below code but it is throwing exception 404 Not found.
Please advice.

Swamy

I want to ask my icloud storage and backup is 3,3 GB available from 5 GB is it also because the apps i have been purchased took that much space?

Note that Photos in your Camera Roll are also backed up to iCloud.
I have found most of the time, this is what is consuming a lot of the iCloud space.
You should regularly copy the photos from iPhone to computer.
-> http://support.apple.com/kb/HT4083
Then delete from the Camera Roll
You can then sync only the photos you want, back to the iPhone, using iTunes.
