Hello,
DPM 2012 latest patches, LTO-4 Tape Library, Server 2008 R2 Sp1 Servers.
1 Protection group synchronizes our File Server to a iSCSI target every 2 Hours. The Long Term Job of the Group starts every Week Day at 8PM.
I think he dont use the Backup from the internal Replica.. The Job is slow, we go 25MB/s thou-put, we got 1Gb Network, HP G7 Servers, why is it soo slow?
Best Regards
Hi.
I have imported and recataloged 4 tapes into dpm2010 server containing a server i need to recover some files from.
The server i am recovering has two drives, c: and h:
Under Recovery and External DPM tapes i can find the server, but only the c: drive is shown under the server name.
H: drive is spanned on 3 of the tapes, and i have the option to copy the files to a network share.
But the h: drive is about 4 TB, so copying it to a network share is not really an option. I only need to recover 2 files.
So the question is, how can i get the h: drive to show up under External DPMtapes?
I am assuming the problem solution approach might be similar to 2012 platform, on the other hand I am hopeful additional troubleshooting help may be available.
This is a fresh bare metal install of Windows 2012 Standard, SQL 2012 SP1 Standard (local) and DPM 2012 SP1 RU2. The problem I am seeing is a large file server (1.3 TB) backup to tape will not use full tape capacity. Instead the tape jobs uses (i.e. 90 GB on a first tape then proceeds to another tape writing 250 GB etc.) This is one PG no problems with disk backups and the tape job will succeed it just uses way too many tapes. No problems during the install were observed - the hardware checks out on latest firmware, bios and driver levels.

Hi,
we are using DPM2007 SP1 for the backup using HP Tape DAT160 USB drive, and backup schedule of long term 2 weeks with data compressed, data size is around 78 GB, the problem is the backup job failed after transferring the whole data and the Tape Offsite Ready showing "Expired", also it is not displaying the Tape contents and asking for Tape recatalogue?
Kind Regards, Reda Kotb Network Administrator Direct: +966 2 6572029 ext 808 reda.kotb@ibscoksa.com
I am using LTO 4 and LTO 5 tapes for long term tape protection on our DPM servers and would like to know if any one has any tips on monitoring the life of the tapes. I believe, as a rule of thumb, that about 260 uses of each tape should expected before the tape is retired and replaced, but I can't find a report or command in DPM (2010) which lets me know how often each tape has been used.
Any help would be greatly appreciated,
Thanks
Chris
I am running DPM 2012 with an HP autoloader - Tape Library - with 8 slots.
Is it possible to specify a specific Protection Group can backup to a specific slot in the tape library?
I know I can setup co-location - to backup more than one group to a tape...
But I need to backup a group to slot 1
then a next group to slot 5
and another group to slot 6
etc
Not sure if this is possible, cannot find anything on this.
Regards,
Hi All,
Currently, I have DPM 2010 running on my server and the DPM protects hundreds of data source. Some are directly saved to disk , some to tape and the rest approach D2D2T method.
What I am currently facing is backup my 70 data sources to tape. ( The size of each data source is about hundreds GB.).
I found it slow while processing backup to tape and of course, all backup process will be delayed.
I'd like to know how to fasten the backup process?
FYI, I have 2 drives available and 35 tapes ( 16 LTO5 ,18 LTO4 and 1 Cleaning Tape).
Many Thanks,
Hery
For the past couple of days I have been getting the following alert on my tape backups:
Cannot verify tape data.
The operation failed because of a protection agent failure. (ID 998 Details: No more data is on the tape (0x80070450)) It has completed the backup but I get this error when performing a verify or when I try and restore. |
I turned on encryption for tape backups last week. When setting it up, I went through a couple of runs of test backups to tape before I got the setup just right. I have 1 tape that encrypted data backed up to, but the certificate wasn't quite right for what I needed, so I had to recreate the certificate after that tape was written. Now, I want to erase the data on the tape and free it up for use by a routine backup job, but the "ForceMarkTapeFree.ps1" script isn't working.
When I run the script, specifying the dpm server, library, and slot when prompted, I get the following:
The operation will remove the following recovery point(s) because they have dependencies on each other: Remove-RecoveryPoint : Length cannot be less than zero. Parameter name: length At C:\Program Files\Microsoft DPM\DPM\bin\ForceMarkTapeFree.ps1:68 char:1 + Remove-RecoveryPoint -RecoveryPoint $rp -ForceDeletion -Confirm:$false+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+ CategoryInfo : NotSpecified: (:) [Remove-RecoveryPoint], ArgumentOutOfRangeException+ FullyQualifiedErrorId : System.ArgumentOutOfRangeException,Microsoft.Internal.EnterpriseStorage.Dls.UI.Cmdlet.RecoveryCmdLets.RemoveRecoveryPoint
What can I do to get this tape cleaned up for re-use?
Hello,
I've an customer with DPM 2012 SP1 (build 4.1.3408), the daily and weekly backup works well, but the monthly backup is not done on the same tape (1 PG by tape).
Do you have an idee ?
Thank you.
When week 4 and end of month both align with the weekend, how can I get DPM to just use the EOM tape? I don't want to come in on holiday to change tapes. This would apply when a long weekend as well

DPM 2010 with latest rollup (version 4.0.1920.0), running on Windows Server 2008 R2.
This is happening consistently since our file server backup expanded to require 5 tapes. When the verification runs, it fails on the 5th tape with "Cannot verify tape data". This happens each time but fails on a different tape each time, there's no way all those tapes could be bad. I've kept track and they've been reused successfully for other protection groups.
Detailed error info:
Data on the tapes Weekly-Files-00000900 (000024L3), Weekly-Files-00000901 (000029L3), Weekly-Files-00000902 (000028L3), Weekly-Files-00000903 (000003L3), Weekly-Files-00000904 (000013L3) cannot be verified for the following reason:
(ID 3309)
DPM encountered a critical error while trying to parse the contents of the tape Weekly-Files-00000904 (000013L3). This may be because the data on this tape is corrupt. (ID 24080 Details: Internal error code: 0x80990AA5) We're using a Dell TL2000 tape library. All other tape backups run fine and verification succeeds, it only fails for this one protection group. Tape colocation is on as well. |
I've got a DPM2012 SP1 server that I'm using to replace my existing DPM2010 server. I've got quite a lot of tapes that I need to import - they show up correctly as (Imported) <tapename> when I inventory them, but when I try to view content on the tape, I get an error saying I need to recatalog. I perform the catalog, and the same error recurs. I'm familiar with the general process, and have done it before in 2010, so I think there's something funky going on. Any help appreciated!
Environment:
DPM2012 SP1 v4.1.3408.0
Windows Server 2008R2 (fully patched) running on VMWare ESXi 5.0
Dell TL2000 library with iSCSI bridge and LTO4 drives
We recently acquired a new tape library (MSL 4048) with 2 LTO5 tape drives. This setup has been working just fine on another backup server running DPM 2007 as well as on this server since about a month ago. No physical or configuration changes on the backup server took place. Error: ID 3302. The number of drives for this library is different from the number of drives detected by DPM. If any drives are out of the library for servicing, ignore this alert; otherwise remap the drives within the library manually. For more information about remmaping tape library drives, see DPM 2010 Operations Guide.
1. I've tried re-installing the drivers. Did not help at all unfortunately.
2. Tried manually mapping the drive with the resulting automatically generated DPMLA.xml actually causing one of the 2 drives to disappear (!).
Automatically generated XML was:
<DriveReMapInfo IsMannuallyMapped="true">
<DriveLibraryAssociation>
<Drive DriveBayIndex="0" SCSILun="0" SCSITargetId="5" SCSIBus="0" SCSIPort="3" SerialNumber="XXXXXXXX1"/>
<Library SCSILun="1" SCSITargetId="5" SCSIBus="0" SCSIPort="3" SerialNumber="XXXXLibrarySN"/>
</DriveLibraryAssociation>
<DriveLibraryAssociation><Drive DriveBayIndex="0" SCSILun="0" SCSITargetId="4" SCSIBus="0" SCSIPort="3" SerialNumber="XXXXXXXX2"/>
<Library SCSILun="-1" SCSITargetId="-1" SCSIBus="-1" SCSIPort="-1" SerialNumber=""/>
</DriveLibraryAssociation>
</DriveReMapInfo>
</LAConfig>
The XML that works for me after some tweaking:
<DriveReMapInfo IsMannuallyMapped="true"><DriveLibraryAssociation>
<Drive DriveBayIndex="0" SCSILun="0" SCSITargetId="4" SCSIBus="0" SCSIPort="3" SerialNumber="XXXXXXXX2"/>
<Library SCSILun="1" SCSITargetId="4" SCSIBus="0" SCSIPort="3" SerialNumber="XXXXLibrarySN"/>
</DriveLibraryAssociation>
</DriveReMapInfo>
</LAConfig>
I've appended the .xml's in case the difference can help anyone make sense out of this issue. If more information is needed I'll do my best to provide it.
Thank you in advance

HI,
when using the optimize tape feature I have following problem.
Using DPM 2012 SP1.
I can only set days, eg: 0 days 1 day, 2 days and so on.
What I want to achieve is, that multiple protection jobs get onto the same tape.
But once the job is finished, it should be marked as offsite ready, I don't want to wait for 24 hours that it sais, offsite ready.
a backup jobs takes daily about 1 1/2 tapes.
Now I see following:
- I set it to 0: Each protection group aren't combined, but are written to separate tapes. Most like as once protection group 1 is ready, it unloads it and marks it as offsite ready, so for the next protection it has to load a new tape. (The need to load/unload a tape with this optimized tapes doesn't make sence anyway, as it does it always, not matter if it's set to 0, 1, 2,...).
- I set it to 1: I have to wait until the next backup starts, before it marks the tape as offsite ready. (24 hours as we do daily on tape) which is basically not useful, as if the tapes are still in there, it could write all tapes full and daily backups have to wait for 1 day to be marked as offsite ready.
- I set it to 2: This would write all tapes full but you have to wait 48 hours.
The only solution I see is:
- If i set the Tapewriteperiodratio to 12 hours, or 6 hours, whatever, it would combine protection groups and mark it offsite ready earlier. But in the GUI only 1 day is possible, I can't set hours.
I found this command but not quite sure about the percentage (fraction) used:
Set-DPMGlobalProperty –DPMServerName <dpm server name> -TapeWritePeriodRatio <fraction>
It sais the fraction is calculated according to the retention period.
But we have daily 7 days, weekly 8 weeks, monthly 12 months.
Percentage would not work for all 3 types, what am I getting wrong here or can it be achieved a different way?
Thanks
Patrick
Hi All,
Annoying problem, we use DPM2012 and a HP D2D Solution, which emulates a HP Tape Drive Library.
When a tape is marked as "off site ready" we have a problem.
Basically, when entering into the "recovery" section, and drilling into a Server and selecting a folder / file etc, under the 'Recovery Type' section, there is an option to "Copy To Tape" at this point we would select from the tape list our "required tape". However, as the "specified" tape has been marked as 'off site ready' it doesnt appear in the list!
Any Ideas?
During the middle of our end of month tap backup run a cleaning job has been started, but has been running for over 20hrs. I have ended up clicking Cancel Cleaning under Management -> Libraries but the job has still not cancelled 2hrs later.
Anybody know how I can cancel this job so I can continue to backup the last few remaining protection groups?
We running DPM 2012 and have one Protection Group configured containing around a dozen servers. The PG is setup for both short-term and long-term protection, ie: we backup to disk each day, which is retained for 90 days, and then we backup to tape once every 3 months, which is taken offsite. The disk backups are working fine although they growing in size quickly rather quickly (currently 8TB). The tape backup worked for 6 months but has started to fail. I we believe is down to insufficient space, ie: too much backup data for a single tape. We are using a single stand-alone HP LTO4 tape drive and manage to squeeze approx. 1TB of backup data onto a tape (using compression). The problem is we aren't receiving any notification to change the tape once its full and the job then fails as I guess it eventually times out.
Why isn't DPM asking for another tape and/or how to we spread this over multiple tapes using a single stand-alone tape drive?
