Does deduplication and Volume Shadow Copy work together?

Hi!
I have a fileserver with five 2TB-disks on it on a 2012 R2 server. I want to enable dedup on it that according to DDPEval.exe would save ~40%. I would also like to enable Volume Shadow Copies on the volumes so the the end user easily could restore removed
files and folders.
I have not found anything from microsoft about use both these features on the same volume, is it supported?
I have done some searching and found that for some users the say that dedup would change so much on the snapshots that it have to delete older snapshots, even though not much data have changed, the dedup force VSC to delete old snapshots.
Any experience with these features co-located on the same volume? Do I need to choose just one of them to use on my volumes?
Thanks!

Hi,
Based on my research, the Shadow Copy and Deduplication could be used together in a Windows Server 2012 R2. The deletion of the old snapshots could be due to the Volume for which the shadow copy being created is more than 64 TB. Volume Shadow Copy Service supports
a volume size of up to 64 TB.
For more detailed information, you could refer to the article below:
Windows 2012 R2 Data Deduplication Leverages Shadow Copies: “LastOptimizationResultMessage : A volume shadow copy could not be created or was unexpectedly deleted”.

Back-up SQL 2005 with NTBACKUP and Volume Shadow Copy

Hi everybody,
I want to make a snapshot backup of a SQL 2005 database with SAP ECC6.
I want to use NTBACKUP to make the snapshot.
Does the database freeze at the moment of the snapshot?
Does anybody use this method?
Thanks in advanche.
Kind regards,
Klaas van Deelen

NTbackup uses VSS to create the copy of FILES.
VSS is not designed to replace your current backup strategy,
VSS will copy a data file, then another, then another etc - heres the problem sapdata1 and sapdata2 will be backed up at DIFFERENT times. if you tried to restore the DB, it would NOT be consistent.If VSS backed up the files OFFLINE - np, it will work.
VSS cache is also on the system (default) as the original data - not really a smart idea for a backup solution.
Use either the SQL tools to backup online to tape/external storage or get the symantec backupexec with the SQL agent to allow for online backups again to tape or nearline storage.

Does 2 firewire audio and video interface can work together on FCP ?

hello,
My audio interface is a TC Electronic Konnekt 24D
my video interface is a Canopus ADVC 110
my hard drives are plugged in firewire too
and I use Final Cut Pro 5.0.4
So, the konnekt is recognized by FCP only when the Canopus is not plugged. And even then, the audio sometimes drop out and sometimes causes the app to crash, so that I have to trash the preferences
When I plug the Canopus, the Konnekt 24D is recognised by OS X but not FCP
I want to use the voice over tool with the konnekt 24D, so what should I do ?
Does 2 firewire audio and video interface can work together ?
If so, maybe I only have a driver problem from TC Electronic.
But if not, I have to change this interface. Let me know if only RME, MOTU, Presonus and Edirol work, as it is said on apple's webpage for hardware compatibility
thanks
eMac G4 1,25 Ghz Mac OS X (10.3.9)
eMac G4 1,25 Ghz 1 Go RAM DDR Mac OS X (10.3.9)

The 1082 does show up as a possible input when I open
the VO tool.
Ok. So an audio interface can be plugged to FCP without crashing the app. Because of the Konnekt driver problem, I wasn't shure of this.
I use my Aja box for export & external monitoring.
All my audio sources run back into the Tascam and I
use the analog mixer in the 1082 to monitor different
sources.
When I view external video, the audio follows it to
keep sync.
that's exactly what I want with other I/O interfaces. I'd like to monitor video with the canopus ADVC 110, and monitor audio with the Konnekt 24D (or another interface if this one is not compatible)
I also imput dailies with a deck or a camera (DV or HDV) but that's not the point here.
I want to imput audio with the Konnekt 24D because of its audio quality. Not audio sync to video dailies. But voice over, in sync with FCP video playback (for me, tha ADVC 110)

The creation of the shadow copy on the backup destination has failed. Detailed Error: The Volume Shadow Copy operation failed with the error 0x80042316

When using Microsoft Backup on a Windows Server 2008 SP2 (not R2 - [Microsoft version 6.0.6002]) I get the error "The creation of the shadow copy on the backup destination has failed. Detailed Error: The Volume Shadow Copy operation failed with the
error 0x80042316"
The odd thing is that when I start the backup manually, it works fine. When it runs automatically the error appears.
When doing a SFC /scannow I do get errors that can't be corrected.
Is there anything short of rebuilding this machine (It's a DC and the only one this office has) I can do to fix this?

Hi,
0x80042316 means "Another shadow copy creation is already in progress". This error could occur when another VSS instance is running.
Is there any third party backup application installed? Try to uninstall it to see the result. And please also check if there is another backup schedule which causes the conflict.
Meanwhile please provide the result of:
vssadmin list providers
vssadmin list writers

Hi,
I do have Crashplan ProE running. It started at 1900 and the Windows Backup starts at 2000. I have modified Crashplan not to start until 2300 to see if that helps.

Next I check Shadow Copies details from volume properties (right click on C or other drive then select properties then click on Shadow Copies Tab) and found it is showing the same error code..
From this error it is clear that the issue is inside the registry hive and due to junk hive shadow copies services not able to working properly.
For me the server have two disk we check disk signature at MBR and found the disk signature was.
Signature disk 0 : 9351912b
Signature disk 0 : FDFBE035
But at registry we found lot of nonexistance signature. Which indicate lot of junk valu inside registry.
Now how can we resolve this issue?
It is very simple just delete the registry key “volume” (registry key “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\STORAGE\Volume”) and reboot the server it will “Volume” registry hive automatically.
Note:
When you remove registry key it is showing error unable to delete, then please right click on it select permission then take ownership and assign full permission to your login account.
Please be careful when you delete registry key because system can fully crashed if you delete or modify wrong registry key.
Your can take a backup of the registry key by exporting.

"DPM uses the Volume Shadow Copy Service (VSS)"

"DPM uses the Volume Shadow Copy Service (VSS) to create a snapshot of the protected data."
According to MS (http://technet.microsoft.com/en-us/library/bb808827.aspx)
Does that mean I have to set asides space on the protected server (a file server), so it can store shadow copies, and the DPM server taps into those shadow copies to create its recovery points etc?
Thanks

Hi Joe,
when you are protecting a file server. DPM will implement a change journal to record all the blocks that have been changed.
Then once the sync starts. The journal is interrogated and will tell DPM which file have been changed.
Then the VSS writer makes a copy of these data and send them to DPM.
You don't need additionnal space or to create a new folder on your server.

Okay before my ipod power and volume buttons werent working but i never dropped it, then one day i was in a app and my ipod froze so i held the home button down and the screen went a bright green color and isnt showing up in itunes

okay I just recently bought a ipod touch 4thG and im already having issues. recently the power and volume buttons stopped working after i syncd my ipod, i shrugged it off figuring it would come back i could live without it. but today I was on my ipod while it was charging and the screen just froze so i pressed and held the home button (being that's the only button that actually works) then the screen turned this bright yellowish lime green color and its not responding to ANYTHING! my computer isnt even reading it when i plug it up into itunes! so what should i do? can anyone help me? i feel like i just wasted $200...

Try:
- iOS: Not responding or does not turn on
- If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

I forgot my ipod password and i didnt use it for along time so it wont even connect to itunes plus it fell in the toilet so my home button and volume button doesnt work what do i do?

Used and allocated Shadow Copy Storage space is showing values in GB .

Hi All ,
This is an production issue and i need an urgent help on this case.
In my environment i am having exchange server 2013 in DAG extended with three sites.On that i am having two mailbox servers in the production site and one mailbox server in remaining two sites.
we have mounted all the mailbox databases in one production mailbox server.Those databases are present in LUN mapped to the production mailbox servers from SAN storage.
Issue :
Few of the mailbox databases are occupying too much of size on the LUN than it's original size.
Say for instance i have kept the mailbox database called "test" which is present on the LUN with the size of 190 GB.On that whole space the mailbox database is occupying only 100GB but on the diskmgmt and also on the explorer it is showing
only the free space as 17 GB.
Finally we have run the below mentioned command and found that the used and allocated shadow storage is occupying the size around 34 GB.
Attached snap for your reference :
Question : How to reclaim the space occupied by the shadow copy storage to the LUN ? If possible someone tell me why this issue is happening ?
Thanks & Regards S.Nithyanandham

Hi,
According to my research and technology, it’s caused by Volume Shadow Copy Service which is used to backup infrastructure for the Microsoft operation systems, as well as a mechanism for creating consistent point-in-time copies of data known as shadow copies.
We can use VssAdmin to create, delete, and list information about shadow copies. More details about Volume Shadow Copy Service, for your reference:
https://technet.microsoft.com/en-us/library/ee923636(v=ws.10).aspx
Besides, this issue may be related to Windows server. I recommend you to contact to Windows Server Team so that you can get more professional suggestions, please refer to:

System State Backup - 2008R2 - Volume Shadow Copy Error

I am attempting to do system state backup in my Test environment. I am running Hyper-V on a standalone "sandbox" server. I have configured a semi-duplicate environment.
We are updating the schema soon, and I would like to do a System State restore for practice and I haven't actually had to do one in about 10 years.
I am running 2008R2 DC as a VM in my Hyper-V environment. It has a C: and E: volume, VSS is enabled on e: and set to Unlimited. I set my set "BackupLocation=e:\adbackups" and attempt to run wbadmin.exe start systemstatebackup -backupTarget:"E:"
(with quotes or without it still fails.
My error from command is Error - Volume Shadow Copy Service operation error (0x800423f4) which appears to be a generic error. In the Backup Event Viewer it shows as Event ID 9, another generic error.
I am running as Domain Admin, and I checked that I have Backup Operator rights. Volume Shadow Copy service is running.

Hello Chris,
This issue occurs if any of the virtual disks attached to the guest VM was created by using the option to copy the contents of a physical disk. Please refer the below mentioned MS KB..
Backup of a Hyper-V virtual machine fails with error 0x800423f4 if the disk signature on a virtual hard disk is the same as a physical disk on the Hyper-V host

Your new router may not correctly handle Bonjour data required by AirPrint. Contact Frontier to correct the router's setup. A firmware update may be required.

Try to restore "as new ipod" without using the latest backup, in case it contains corrupt data causing your problem. How to back up your data and set up as a new device

My on/off button and volume buttons stopped working.

For no apparent reason, the on/off button and volume buttons stopped working. iPod touch 4th gen with 4.3.3 installed.

You can try a couple of things.
First a hard reboot: hold the sleep/wake and home button down until the unit shuts off and boots back up to the Apple screen.
Second restore the device py plugging it into iTunes and under the device summary screen click restore. You want to restore from backup to make sure all your info is synced back to the iPod at the end. Depending on how much stuff is on there this can take a while.
Thrid, take it to the Apple Store and have a Genius look at it. Depending you how bussy your local Apple store is you probably want to make a reservation first.

I bought a mic for my ipod touch 2nd gen and the mic works yet when its plugged in the speakers dont work, meaning i cant hear, so skype and other similar apps are un-useable, is there a way in which the mic and speakers will both work together?

Looking at the details for this mic, it appears that the app has to have the option to use the internal specak when a mic is plugged into the headphone jack. Specifically:
NOTE: When MityMic is plugged into your iPod/iPhone you won’t be able to use the onboard speaker for sound output. You must remove the MityMic then play back your recordings. (The Skype app has an option to enable the onboard speaker even when the mic is plugged in, so you could use MityMic for placing Skype calls. However most other apps do not have this function.)

Does deduplication and Volume Shadow Copy work together?
