Simply put, my DPM 2010 jobs for a specific PS is failing due to the vss shadowstorage running out of space. It is not an ideal backup scenario. I'll give the details below - but what I need to figure out, is if the size of the vss shadowstorage volume can be predicted based on total data size, and data churn of two different VSS operations.
I of course have extremely limited SAN space space left and can either expand the e:\ by a specific amount. Or - attach another SAN volume, move the DPM shadowStorage from e:\ to new volume, and leave as UNBOUNDED. What can I do to figure out these numbers for size expansion or new volume size?
SQL VSS jobs are dealing with ~400GB of SQL data to make full backups from E:\ to D:\ -- how much space would it need for this?
DPM VSS jobs are dealing with the consistency check of 2.1TB of .bkf files / transaction log Data on D:\ with a daily churn of ~420GB. --
~10% of the volume data totals? So - maybe 260GB of free space?
As mention, my situation and details.
At this point, DPM needs to run a consistency check of 2.1TB of file data - with a daily churn of 415GB. Should take my environment about 72 Hours +/- 12 Hours. In the meantime, the same volume that houses the DPM shadowstorage volume runs out of space every day when the SQL VSS Writer runs its own jobs to do full backups of each DB... thats where the 415GB of churn is from - not SQL data changes, but I'm backing up full backups of the SQL databases.
DPM 2010 running on a 2008 R2 SP1 DPM server - protecting a clustered 2008 R2 SP1 SQL server -
D:\ = 2.5TB (50GB Free) SAN Volume
E:\ = 600GB (140GB Free) SQL Databases -- also home to the shadowStorage Volumes - the volume that is running out of space.
Due to infrastructure, and old procedures - SQL databases are not being backed up directly via DPM, but rather the SQL server is running its own backup jobs of the Databases on E:\ to its D:\ (both are Fiber SAN Attached) - reason being that our SQL DBA can then restore to the minute with the transaction logs all at the speed of our SAN.
DPM is protecting the 2.5TB of .bkf and log files. The shadowstorage volume of D:\ is set to E:\ -- and until recently has not been a problem.
Hi All,
Is there an possibility to swap disks in DPM for rotation backup.
Methodology as follows,
There are 2 external hard disks that will be used for data backup, and the disks will be rotated every Month. For instance, data backed up for Month-1 on HDD-1 and then for Month-2 data is backed up on HDD-2. For Month-3 HDD-1 is used, Month-4 data is backed up on HDD-2 and so on.
Please let me know, this is possible. If yes please guide me.
Thanks in advance.!!!
Hi,
We currenlty have System Center Data Protection Manager Service Pack 1 installed on Windows Server 2012. We have a few file shares on a QNAP Nas box i would like to backup, anyone know how i can do this???
Thanks

I haven't been able to run a backup for some time now, and after troubleshooting with the LiveVault (Autonomy) techs, we see that the error is with the DPM Writer ... error below :
Writer name: 'DPM Writer'

The fix gets the DPM Writer to a "No Error" state, but once I run the backup, it fails, and the DPM Writer goes to the "Non-Retryable Error" again.
Any help would be greatly appreciated so I can get a current off-site backup.
Thanks!
Hi everybody.
I'm new to SCDPM in genreral, and i'm having a few issues with the server.
In short, i'm going to list my setup underneath.
Physical HP server, Windows server 2008 R2, SCDPM 2012 SP1, 32gb ram, 279gb system drive (at the moment 189gb free), 32tb DAS with 27tb raid 50 partition.
All of the sudden our server becomes unresponsive after working perfectly for a few months, so i had to Cold boot it.
Now the server is up and running, but i have some errors in my event log saying that the system drive is full, even though it is not.
I suspect some shadow copies is messing stuff up.
Please tell if you need more information to analyse this problem.
Thanks in advance :-)

Actually, this USB flash drive could be detected by my computer. But, when I tried to open it, a “not formatted error” message popped out. The “properties” of this drive was also displayed as “RAW”. So, how could I access my inner data and fix this “RAW” problem? Please help me fix this!
We're about to setup a new 2-node cluster, replacing our existing one.
Its a physical cluster running 2008R2. The current cluster is protected by Another Product.
All user data is obviously going to be migrated to the new cluster.
We'll need a Daily backup of all the files. Not sure how many files each drive has but we're talking millions.
My abstract questions Before utilizing dpm here is are;
Is DPM 2012 capable to fully protect a Windows 2012 HA Failover cluster with SC SP1 installed? Or is it still 2008R2 to be on the safe side?
What are the current limitations in dpm 2012 regarding amount of files on a drive/mp?
What are the recommended implementation when protecting Fileclusters
Will we likely run into situations where DPM will triggers consistency-checks that wont have time to complete til next scheduled job is triggered? Have read other posts here about frequent access to many files, like a I/O-intensive application or a antivirus tends to be an issue
If so, what options does one have to trim this, except splitting up data on more disks which doesn't feel like an options since design is set by other factors? I'm talking settings in DPM to i.e reducing consistency checks, speed them up or so.
disks are between 200gb to 2100gb.

A user creates a file and then accidentally deletes it later that day (before a recovery point is created, but after synchronization occurs). In this situation, is there any way to recover the deleted file from the synchronized version, or do later synchronizations overwrite earlier ones and make recovery impossible? In other words, can I recover from a certain synchronization time or only the latest?
From the DPM planning guide:
"For example, a volume is synchronized hourly and a recovery point for the volume is created at 8:00 A.M., 12:00 P.M., and 6 P.M. A user makes changes to a file on the volume at 1:30 P.M.; however, when another user makes changes an hour later, the file is inadvertently corrupted, and you are asked to recover the file with the first user's changes. Because the changes at 1:30 P.M. were made after the most recent recovery point was created at 12:00 P.M., you cannot recover the file from the most recent recovery point. However, you can manually create a recovery point from the appropriate synchronization of that replica and then recover the file from that new recovery point."
Does that last line not apply if synchronization has occurred after the deletion?
Recovery points: 8:00 AM, 12:00 PM, 6:00 PM
Synchronization: 15 minutes
How do you avoid this situation? I am aware of the recovery point quantity limitation. Shadow copies on the file server? Recycle Bin on the file server?
We have a number of large backup files stored on disk produced by a third party backup tool. We need to back these large files up periodically to tape however this process tends to be a little on the slow side.
For instance, if I have a volume with the following files on...
LargeFile.1
LargeFile.2
LargeFile.3
LargeFile4
... and I kick off a tape based backup of the volume these files sit on, then tape backup overruns.
What happens if LargeFile.2 is modified on disk and is actively used during the tape backup? Am I correct in thinking that a snapshot of the whole volume is taken via VSS when the tape backup starts, then the tape backup uses this VSS snapshot as the data source for the tape backup? Therefore if modifications are made to LargeFile.2 whilst the backup to tape is running the data going to tape is unaffected and thus not in a corrupt state?
Hello,
I have already tried to search for an answer for this question but still don't really "get it". I understand that previous versions of DPM use Single Instance Storage, this is the first time I have used DPM and I'm starting at version 2012 installed on server 2012. In my testing I can see that DPM 2012 seems to create a new volume for each system its backing up, so everything looks separated across different volumes, I also notice that data deduplication feature is enabled which is assume DPM did that during installation, however it isn't actually enabled on any particular volume so it isn't doing anything. Naturally I would have assumed that DPM 2012 being a brand new product and compatible with server 2012 that it would utilise the data deduplication feature of the server..... but it's not. so my question is, does DPM 2012 utilise data deduplication or single instance storage, if not how can we save lots of data from duplicate backups of things like DC's, File servers and Exchange Mailbox servers? all of which have high levels of duplicated data.
Also, I don't full understand the difference between SIS and De-dupe, am I correct in saying that SIS just removes the need for an entire duplicated file (regardless of its filename) and de-dupe actually compares bits and bytes of data across multiple files regardless of file type, name or size...?
thanks for any further information

I'm trying to perform a Integrity Check on a protected server that is across a WAN and I get the following Error:
DPM encountered an error while performing an operation for \\?\Volume{e0f28da5-8c48-11e2-941c-806e6f6e6963}\sharedfolder\Admin\Marketing\Battery display pack\Thumbs.db on dpmservername.SEC.local (ID 2033 Details: Internal error code: 0x80990AA5)
Sometimes if fails on a pdf file, sometimes a jpg, it's just random.
I was finally able to perform a Consistency check after three tries, however, I want to do an integrity check as that allows me to see if indeed there was anything inconsistent, whereas a consistency check doesn't report thing being wrong, it just corrects them if they are.
Details:
DPM2012 SP1 Server on 2008R2 SP1
10MBps link between sites
1.7TB of Data on the protected server
Server2003 OS on the protected server.

Here is my error
The recovery jobs for Volume E:\ that started at Friday, May 3, 2013 9:32:14 AM, with the destination of DPM0.abc.forest.org, have completed. Most or all jobs failed to recover the requested data. (ID 3111)
DPM is attempting to backup or restore deduped files, which requires target to be a NTFS volume and deduplication should be disabled for that volume;. (ID 30242 Details: Internal error code: 0x80990AD2)
I might be nitpicking here but... My volume is NTFS and it says deduplication "should" be disabled which indicates that it doesnt have to be.
Why can i not restore to a location with deduplication turned on? What does it even care my dedupe job should be fully independent of putting data on the drive.
My biggest grip is i just have not other place to restore this data to. Its about 15TB worth of data and the drive has plenty of space to restore.
