What type of backup DPM takes in recovery point volume

Hi,
Please help me to understand what type of backup DPM takes in recovery point volume as it takes more disk space as compare to replica point volume, though replica point volume is initial full copy of data source and why it takes more disk space.
Thanks in advance.

Thanks for valuable inputs.
But I have still doubt on my understanding i.e.
I have calculated disk space required as per Microsoft formulas given on above mentioned link. Below table is there output.
Application
Data Size
Retention Range in Days
Replica Volume
Recovery Point Volume
Total Volume
Exchange Mailbox
700 GB
7
906 GB
1962 GB
2868 GB
SQL Database
100 GB
7
125 GB
107 GB
232 GB
File & Folders
500 GB
7
750 GB
72 GB
822 GB
Virtual Machines
700 GB
7
1050 GB
100 GB
1150 GB
So as we are considering during sync frequency DPM transfers changed data to recovery point volume plus volume shadow copy of replica during each express full for 7 days (as per above table) then how/why required disk space for recovery point volume is less
as compare to replica point volume for SQL, File, VM apps?
Please help me to understand.
Does anyone else have an idea regarding the formulas given by MS to calculate required disk space?
Please help.

DPM 2012 R2 All backups fail with recovery point volume not available after resizing OS disk

I resized the C drive partition of my DPM server (the data is on a separate dedicated array) and everything failed. I put it back but everything is still failing with the same problem as here:
DPM 2007: The recovery point volume is not available?
I've run chkdsk for a couple and both have given the following after doing 3 stages:
Windows has scanned the file system and found no problems.
No further action is required.
The backups still fail and the only error information I can find in the event logs is:
Backup job for datasource: Online\<VM name> on production server: <host FQDN> failed.
How can I find out what the problem actually is?
Is it possible to resize the C drive containing a DPM install? If so what can it be safely resized to? It easily met the minimum requirements and I don't know of anything in the documentation that says resizing the OS disk may cause issues.
Preparing your environment for System Center 2012 R2 Data Protection Manager (DPM)

Hi,
Resizing the boot partition (usually C:) should not effect DPM in any way. DPM writes directly to it's volumes contained in the storage pool and not through the mount points on the C: drive. So is the DPM UI showing
missing volume next to some data sources ? Try doing a DPM disk rescan and see if that removes the missing volume flag.

DPM 2012 R2 UR4 - DPM could not set security permissions on the replica or recovery point volume that was created.

Hi All,
I am running a fresh install of SCDPM 2012 R2 with a protection group that is backing up the 'C:\', Bare Metal and System State of some VMs. If i add any additional servers to the group since the first creation it returns the following error:
Modify protection group: System State & Bare Metal Recovery failed:
Error 419: DPM could not set security permissions on the replica or recovery point volume that was created.
Error details: The process cannot access the file because it is being used by another process
Recommended action: Review the error details, take appropriate action and retry the operation.
If i re-create the whole protection group it works fine.
Could any one advise any further diagnostics I can do to try and locate the reason behind not being able to modify the group after the first creation? I can add new servers to other PGs without any issues.
Thanks in advance,
Dan

If you are protecting any of the system state/BMR protection. Can you stop protection by deleting the older recovery points and then recreate the protection group.
This thread mentions this to be a hardware issue, albeit with less information on what exact hardware issue:

Understanding replica volume and recovery point volume usage with SQL Express Full Backup

I am running some trials to test DPM 2012 R2's suitability for protection a set of SQL Server databases and I am trying to understand what happens when I create a recovery point with Express Full Backup.
The databases use simple recovery model and in the tests I have made so far I have loaded more data into the databases between recovery points since that will be a typical scenario - the databases will grow over time. The database files are set to autogrowth
by 10%
I have been looking at the change in USED space in the replica volume and in the recovery point volume after new recovery points and have a hard time understanding it.
After the first test where data was loaded into the database and an Express Full Backup recovery point was created, I saw an increase in used space in the replica volume of 85 Gb and 29 GB in the recovery point volume. That is somewhat more than I think
the database grew (I realize that should have monitored that, but did not), but anyway it is not completely far out.
In the next test I did the same thing except I loaded twice as much data into the database.
Here is where it gets odd: This causes zero increased usage in the replica volume and 33 GB increased use in the recovery point volume.
I do not understand why the replica volume use increases with some recovery points and not with others.
Note that I am only discussing increased usage in the volumes - not actual volume growth. The volumes are still their original size.
I have been using 3-4 days on the test and the retention period is set to 12 days, so nothing should be expired yet.

Hi,
The replica volume usage represents the physical database file(s) size. The database file size on the replica should be equal to the database file size on the protected server. This is both .mdf and .ldf files. If when you load data
into the database and you overwrite current tables versus adding new ones, or if there is white space in the database files and the load simply uses that white space, then there will not be any increase in the file size, so there will not be any increase
in the replica used space.
The recovery point volume will only contain delta changes applied to the database files. As the changed blocks overwrite the files on the replica during express full backup, VSS (volsnap.sys) driver copies the old blocks about to be overwritten
to the recovery point volume before allowing the change to be applied to the file on the replica.
Hope this helps explain what you are seeing.

Microsoft Azure Backups not reducing available recovery points or destination usage after retention period has been reduced.

Microsoft Azure Backups not reducing available recovery points or destination usage after retention period has been reduced.
I had the retention period set to 30 day with around 6.8TB of backups. Over a week ago I changed the retention period down to 7 days, and it took a couple of days for the total recovery points to go down to 7. The destination usage was still going up.
I have come in today (monday) and the total backups is now 10 and the destination usage is now 7.57TB.
I only have the one server backing up to Azure Backups Services.
My questions are;
1. how long does it take for azure to delete backups from outside the retention period*
2. why are there move recovery points that the retention period?
3. Is there a way to purge just the backups outside the retention period?
*It does say the backup agent, "space allocation data is updated on a daily basis".
It would be a great help if anyone had some information on this as the storage costs are getting very high.
Thanks for the help in advance

Hi,
Any update for this issue?
If issue still exists, please open a case from http://azure.microsoft.com/en-us/support/options/, pick Recovery Services & problem type as “Backup”.
Also please let me know the case ID so I can forward it to related support team for monitoring. Thank you for your time.

Exchange 2010 Databases' recovery point volume is too large.

I have DPM 2012 SP1 backing up exchange databases exclusively.
One protection group is for Exchange 2010 and the other is for exchange 2013. EseUtil.exe is only working for 2013.
The 2010 databases have gigantic recovery volumes (40 GB for a 95 GB database!) while it is less than 1 GB used for Exchange 2013 ones (55 GB replica)
The 2010 sync every one hour and the 2013 sync every 15 minutes. both have express backup at 8 PM and retention for 1 day.
is there any explanation for this behavior??
the capacity on the DPM server is limited.

Hi,
It could be page zeroing in Exchange 2010.

DPM 2012 R2 Online Protection - Online Recovery Point Creation Failed

Hi
We are moving from protecting our DPM server with another server to use an Azure Data Vault. 2 of the Protection Groups work fine, but the third - protecting a pair of Folders - fails. On the DPM MMC it shows Online recovery point creation
failed, and in the Event Log it shows -
Creation of online recovery points for D:\ on blah.blah.co.uk have failed. The last online recovery point creation failed for the following reason: (ID: 3188)
The operation attempted cannot be performed at this time because a backup or restore operation is currently running. (ID: 100049)
The DPM server is the only one conducting any backups. The target server is Win 2003 (for the moment).
Could anyone give me any pointers?
Thanks

Ok, nobody any more ideas?
The latest test involved 9.75GB on the protected server. I created the protection group and this was the outcome:
Replica volume: 15.98 GB allocated, 0 KB used | Recovery point volume: 3.70 GB allocated, 0 KB used
I then create a recovery point and then deleted all 9.75GB on the protected server. And did a full restore from DPM. It then gave following outcome:
Replica volume: 15.98 GB allocated, 9.85 GB used | Recovery point volume: 3.70 GB allocated, 654.86 MB used
Then after the creation of the first recovery point (sync + recovery point), I get this:
Replica volume: 15.98 GB allocated, 4.79 GB used | Recovery point volume: 13.70 GB allocated, 3.27 GB used
As you can see DPM took the 9.75GB and added it to the recovery volume. And strangly it took away half of the replica volume.
In addition I get 3 entried in my logs:
1) The used disk space on the computer running DPM for the recovery point volume of E:\ has exceeded the threshold value of 90% (DPM accounts 600 MB for internal usage in addition to free space available). If you do not allocate more disk space,
synchronization jobs may fail due to insufficient disk space. (ID: 3169)
2) Synchronization jobs for E:\ on ****** have failed. (ID: 3115)DPM has run out of free space on the recovery point volume and will fail synchronization for E:\ on ***** in order to prevent existing recovery points from being
deleted. (ID: 30195)
3) Creation of recovery points for E:\ on ****** have failed. The last recovery point creation failed for the following reason: (ID: 3114)DPM does not have sufficient storage space available on the recovery point volume to create
new recovery points. (ID: 214)
I hope someone can help me with this.

Maurice

Old recovery points seems to not being cleaned up

I'm running a Windows Server 2012 server with DPM 2012 SP1, acting as a secondary DPM server for a couple of primary servers. However, the last 5-6 weeks it has begun to behave very strange. Suddenly, I get a lot of "Recovery Point volume threshold
exceeded", "DPM does not have sufficient storage space available on the recovery point volume to create new recovery Points" and "The used disk space on the computer running DPM for the recovery point volume of SQL Server 2008 database
XXXXX\DB(servername.domain.com) has exceeded the threshold value of 90% (DPM accounts 600 MB for internal usage in addition to free space available). If you do not allocate more disk space, synchronization jobs may fail due to insufficient disk space. (ID
3169).
All of these alerts seem to have a common source - disk space of course, but there is currently 8 TB free in the DPM disk pool. However, I have a feeling that all of this started when we added another DPM disk to the storage pool. Could it be that DPM doesn't
clean up expired disk data correctly any longer?

Hi,
If the pruneshadowcopiesdpm201.ps1 is not completing, hangs, or crashes, then that needs to be addressed as that will definitely cause storage usage problems.
In the meantime you can use this powershell script to delete old recovery points to help free disk space. It will prompt to select a datasource, then a date to delete all recovery points made before that time.

What type dvd to use for recovery?

I need to know what type dvd to use to make recovery disc? I read a dvd+r verbatum or sony on one post then aother said dvd-r Im confused please help! also how many disc will I need ? I have a X505 Q870 any help would be greatly appreciated. Thanks

it really depends on your laptop. some will work with +r and some with -r. you will need anywhere between 2 and 6 dvds. you should be fine with anything other than memorex.

Backup DPM 2012 SP1 from Recovery console

Hi
I have a problem. I have a server with Windows Server 2008 R2 and DPM 2012 SP1. Because of a recent RAID controler crash i am unable to fix this server to boot to windows. I can only get into recovery console. I see the volumes normaly! So here is a million
dolar question. How can i backup DPM databases from recovery console so that i can make a full restore when i freshly install new windows and DPM?
Thanks for all your help in advance.
Boštjan

Hi,
only Thing you need ist MDF and LDF files from DPMDB.
Try to copy These two files.
Install your new Serve with same Name and same DPM version
Restore DB with SQL Management Studio and overwrite the new and existing one
present DPM Backupstorage to the new server
Run dpmsync -sync

SCDPM 2012 R2 Recovery Point usage shows 0k used

After upgrading to Microsoft System Center Data Protection Manager 2012 R2 I have noticed something odd. The protection groups all have a recovery point/shadow copy allocation but most all groups show a 0k used amount. For example,
my Exchange database protection group has multiple databases. I highlight one and it shows Recovery Point Volume 249.56GB allocated/0k used and it does this same thing for all databases. Exchange is not the only one having this odd behavior. But,
I can go to Recovery, select the database and show the calendar with all the recovery points and even recover a database from it. Why would the Recovery Point volume be showing nothing used?

Maybe I am mis-understanding your post. Are you saying this or just quoting the Rollup?? I apologize if I misunderstood. Let me know and I will mark yours as the answer!! Sorry!!
Mike wrote
"UPDATE: We have located the code defect and will provide a fix in the next rollup (UR2)."
And now
UR2 release http://support.microsoft.com/kb/2958100 with fix issue "DPM does not display Recovery Point Volume Used Space. It is always set to
0 KB." !
Have a nice day !!!

What type of DVD should I use for Windows Backup?

I am wanting to do my Windows Backup and I was wondering what type of DVD media I should use. Is it better to use a RW or only R type DVD.
I have an HP Omni 220-1180qd, A5W89AV#ABA, running Win7 64 bit.
I thought I read it can use CD's, DVD's but I want to know which would be the better choice.
Thanks for any help and all help is appreciated.
This question was solved.
View Solution.

Honestly, an external hard drive would be a better choice. The difference between +R and +R/W is that +R is "Recordable" and +R/W is "Re-Writable". If you intend on making periodic backups, go with an extrernal hard drive... If you intend on making very few backups, consider the DVD+R discs.

Also when I figure it out converting these 1080p movies to a watchable format on my TV screen; probally going to have to wait till I get a blue-ray burner,
Trying to figure if I should go all out on my next purchase with multiple cores.
