Are long term backups created from short term tape full + incremental?

Does DPM use short term tape, Full + incrementals to create the long term Tape backups?
For example, if i run a short term to tape full with incremental against a computer with a 1 week retention then run a long term recovery point every 1 week for for 4 weeks and 1 recovery point every month for 6 months.
will all the long term RPs actually run a full backup or will they build one from the previous full plus incremental?
My question is two fold,
1. i am concerned about total long term storage
2. I am concerned about time needed to complete the full backup.
Thanks!

DPM doesn't support incremental backups to Tape. Tape Backups are always full.

Editing from a DVD created from a VHS tape

I have been coping a lot of VHS tapes of the kids to DVD's (DVD-RW). Now I want to load the DVD into iMovie and edit. Do anyone know of a program that will do this?

Go to the above link and download the Cinematize 2 product. This works great, and it is very easy to use. I transfered all of my old HI-8 videos to DVD. I had the SAME problem as you, I could not load the new DVDs to iMovie. Cinematize allows you to "cinematize" the DVD, to allow it to work in iMovie. I am now able to edit all of my old Hi-8 videos, because Cinematize allowed iMovie to read my newly formed DVDs.

DPM 2012 SP1 long term backup fails when protected server reboots

Hi,
we're using DPM 2012 SP1 with Short-term and long-term protection.
We use a daily short-term backup to disk and a weekly long-term to tape.
We are noticing that when a long-term tape backup is running, it fails when we reboot one of the protected servers.
Is anyone else having this issue ? I assumed the long-term tape backup will be created from a disk-recovery point.

Hi,
What is the detailed error code in the properties of the failed initial replica or consistency check job ?

DPM 2012 R2 Long Term not backing up on correct day

Howdy,
I have created a Protection group w/both short and long term protections. The short term backup is to disk, Monday through Thursday, and the long term backup up is on Fridays to tape. (See images below) Seems simple enough, however for some reason the long
term Friday shows up on Thursday the same time the the short term backups are run. I didn't know that was possibly, but more importantly why is this happening?
I've done as much research as I can do on the web, I'm hoping someone here can weigh in. Thanks in advance.

Hi Janaka,
This is by design, all Long term tape backups are taken from the last successful disk based backup. In your case, your last disk based backup is Thursday, and no data has changed since then, so DPM will mount Thursdays disk based recovery point and
copy it to tape and the time of the recovery point will be the same as Thursday since the version of the data is exactly the same.

Extending Long-Term Protection (tape)

Hi all,
This should hopefully be a simple Q&A. I'm using local disk for short-term backup - roughly 30 days. I also have a tape library attached that I use for Long-Term protection. The protection group is configured to keep weekly run tapes for
8 weeks, and the monthly tapes are marked to keep for 3 years.
If I reconfigure the protection group to keep the monthly tapes for 5 years, will it update the time-stamp for any previously writtent monthly tape?
Example: On May 1, a monthly tape was written w/ a 3 year retention period (as per the protection group). If I edit the PG to reflect 5 years instead of 3, will that tape on May 1 update with the 5 year retention policy? Or will it still only
reflect 3 years, because that was the policy at the time of the write?
Thanks!

Hi,
Yes, by default the monthly tape recovery points should reflect the new recovery retention period. We introduced a registry setting to prevent that from occurring for customers who do not want the default behavior.
DPM 2012 Sp1 UR2 KB2706783 see Issue 8
Expiry dates for valid datasets that are already written to tape are changed when the retention range is changed during a protection group modification.
For example, a protection group is configured for long-term tape recovery points with custom long-term recovery goals. Recovery Goal 1 has a smaller retention range than other recovery goals. In this configuration, if a protection group is changed to remove
Recovery Goal 1 and to keep other recovery goals, the datasets that were created by using Recovery Goal 1 have their retention range changed to the retention range of the other recovery goals.
To work around this problem, create the IsDatasetExpiryDateChangeInModifyPgAllowed DWORD under the following subkey, and then set its value to 0:
HKEY_LOCAL_MACHINE\Software\Microsoft\Microsoft Data Protection Manager\Configuration\MediaManager

What actually gets written to tape by long-term protection?

I've been reviewing our long term recovery goals and am confused by the Customize Recovery Goal screen. The only documentation I can find for it only gives brief descriptions and is for 2010, I'm using 2012 R2.
Customizing Recovery Goals for Long-Term Protection
http://technet.microsoft.com/en-us/library/ff399209.aspx
I notice it says 'Back up every:' under the recovery goals, not 'colocate'. Does this mean that it will take a backup and write it directly to tape instead of writing the recovery points on disk to tape?
The specify long-term goals screen in the Modify Group wizard says 'All long-term tape-based protection uses full backups.' Does this mean the file and application recovery points from the short term protection aren't written to tape?

Hi,
<snip>
What actually gets written to tape by long-term protection?
>snip<
It really depends if you are using short-term to disk or not.
1) You are using short-term to disk, long term to tape (D2D2T)
       In this configuration the last successful disk based recovery point is written to tape.
       The data is read from DPM recovery point and copied to tape.
2) You are using short-term to tape and long term to tape (D2T2T)
     The first LT recovery goal is a full backup taken from the protected server.
      Other LT goals are tape copies from lesser goals, so you need multiple tape drives.
As noted - all long term tape backups are full backups, no incremental backups are possible.

Long term inspection

Dear Gurus,
Scenerion is as material is produced though process order it is checked for quality, but some characteristics are checked for long duration. And results are getting after 5-6 days . Uptill that material cant retain in quality lot. So some temperary result has to give for the lot clearance. I want to use Long term inspection functionality in that. So what are the steps to impement and how can i record results once i given UD.
thanks in advance
ACP

Hi
So what are the steps to impement and how can i record results once i given UD.
In a task list there can be many char that can be long term.
You only have to define Long term in control indicator of the char.
Once you define that .......you can do result recording for all the char(including the LT char) & take UD
System then change the status of the lot as LTIN after you take UD.
so when you want to do RR for those char which requie 5-6 days to inspect ..you have to go to the RR-->system will show only those long term char here.& disply msg "char are long term.do you want to inspect"
click on ok & do RR for those char even after UD is taken.
I hope you understood.
Regards
Sujit

Short term tape based protection

hi,
I am taking short term protection using tape for file server. and retention period is 2 weeks. so it is weekly full backup (which is defined in short term protection)
i can see that after 7 days it is taking new tape for full backup and for incremental backup.
i want to minimize usage of tapes. how can i do that? since a lots of space is wasted on tape.
--joseph

Hi,
This is by design and no way to change it.
See the following TechNet page:
How DPM Uses Tape Libraries
http://technet.microsoft.com/en-us/library/hh757885.aspx
Short-term tape "full and incremental" option
The full backup will require a free tape for each scheduled job, and the incremental backup for all data sources will be appended to a single separate tape.
As tapes fill up, new free tapes will be allocated.
When the next full backup occurs, it will require another free tape, and subsequent incremental backups will be appended to another free tape.

[TRM-TM] Transfer from Long-term liab. to Short-term liab.

When I create a long-term loan using the transaction manager, it will be posted to the long-term liab. account, but after the remaining period of a loan become shorter than 1 year, I need to transfer it from the long-term liab. account to short-term liab.
I want to know if there is standard system function can fulfill this requirement, or someone could suggest me a solution.

Hi,
Yes you can do this. You can use capital reposting - grouping/splitting of loans function for acheiving this.
You can group this loan and transfer the remaining capital of this loan to another loan. It is generally used for takeover of loan by a different partner, but in your case specify the same partner.
The Group Contract function allows you to create one contract from several contracts for accounting purposes or to transfer parts of several contracts to another contract. The outstanding capital (remaining debt) of one or more contracts is transferred either fully or in part to another contract. This is necessary, for example, when a different borrower takes on the remaining debt of a loan.

DPM 2010 Short and Long Term goals

My question is related to size restrictions.
Our existing DPM 2010 is setup with two protections groups, System State, and a Default (file) protection group. Both are set up the same. A co worker recently had to re-create a protection group due to his negligence and deleted it without looking at how
it was setup in the first place, since then I've been having errors in backing up to tape:
Synchronization frequency is set to just before recovery point
Short term goals are:
Recovery points are at 8:00 AM, 12:00PM, 6:00PM Everyday, Express Full is 8:00PM Everyday
Long term goals are:
Retention range 2 weeks, Frequency Weekly (1 recovery point every 1 week for the last 2 weeks)
Full backups are set to Saturday at 11:00 PM
Here's the thing, we have 3x3TB external drives that, historically have been swapped out weekly (Monday mornings, using Firestreamer for tape emulation). Since the co-worker broke, and re-created the protection groups, when we view DPM Console on Monday
morning, we see that the backup jobs are failing, the 3TB drive is full.
Could this 3TB drive be full due to this weekly swapping out when it is set to a retention range of 2 weeks? Obviously, it could be because the protection group actually contains that much data, but I'm trying to wrap my head around sync frequency, recovery
points and how that works into recovery goals.
Any help is appreciated.

Hi,
Right. After the registry key is added, all new recovery points written to tape will show they expire at midnight (12:00am) on they day they expire so any tape jobs that run later that day will be able to use that tape after the expiry
date.
To prevent tape jobs from failing because there are no tapes available, you can also add this registry value.
During a new tape backup or if a tape becomes full and there are no other tapes marked free, Free (contains data) or expired in the library, DPM will raise an alert to prompt for another free tape to continue backup. The same is true during a
restore, if the needed tape is not in the library an alert will be raised. By Default, DPM It will wait for
1 hour before failing the job.
This prompting timeout can be configured by the registry entry “PromptingTimeOut” under “HKLM\Software\Microsoft\Microsoft Data Protection Manager\1.0\Prompting”
PromptingTimeOut:REG_Dword:43200000 (dec) = 12hrs
The Formula is (#hrs * 1000 * 60 * 60)
1HR = 1*1000*60*60 = 3600000 decimal
So for each hour to wait, multiply by 3600000.
8hrs = 28800000 decimal
Restart the DPMRA service.

Transfer of results From M.I.C to Batch in case of Long Term Inspection

Hi Gurus,
We have maintained long term inspection in the control indicators in the inspection plan and also assigned Class Characteristics to M.I.C.
We are following these procedure for Result recording.
1) we are doing U.D and then posting to unrestriced stock
2) We are doing result recording.
In our case the result from M.I.C are not transferred to Batch
and the Status is Long Term Inspection,Short inspection completed and transfer posting completed.We are not getting Status Long Term Inspection completedand the results are not transferred to batch.What might the reason for this.
Regards
Amit

You must redo the UD to have the results transfer. (Providing of course your setup is correct and the transfer happens for regular characteristics at the first UD)
I would recommend that you create two UD codes. The first one might be ALTP - Accepted, Long-term Pending.
After the LT characteristic is recorded, use QA12 to change the UD to ACC - Accept. When you save, the resutls should be transferred.

Snapshot rollup with Long term backup to Tape

I need to reconfigure the short term disk storage, and wanted to know if I create a Long Term backup to tape, does that
store or encompass all the "snapshot/short term" backups that I have on disk?
If so, I will be able to remove all my disk backups, reconfigure it as needed, and re-enable the short term backups without losing any of my historical backups. (For Legal reasons)
Thanks!

Hi,
No, Long term to tape are also "point in time" backups and if started now will only contain new recovery points. The ability to make backups of previous recovery points is not very easy, you basically need to restore a disk based RP to tape, unfortunately,
every restored recovery point to tape requires a separate tape.

Auto Conversionn long term fixed deposit to short term fixed deposit

Hi SAP Experrts,
We are using CFM system and I have the following scenario
We invest funds in long term fixed deposit. On maturity data LTI should automatically convert STI and the balance in LTI account should get transfered to STI account. Has any one dealt with this kind of scenario, If yes please let me know how to configure this scenario in Account determination
Thanks in Advance

Hi,
Like Prasad said you can do a valuation class transfer. But this is not available in earlier releases ( I think only from EH2).
But it would be better if we could know the business logic for such a transfer. Why do you want to transfer to a short term FD on maturity date. On maturity date, the long term FD gets matured and that closes the investment correct. In case if your requirement is that the maturity amount is invested in another short term FD, then you can as well create a new short term FD transaction for the same or in case if the FD is extended for some time then you can check with the option of roll over.

Ravi

DPM 2012 - stand alone drive - Short/Long term protection to tape

We are migrating from BE to DPM 2012. I'm trying to configure DPM 2012 for both short term & long term protection - both using tape (stand alone drive). The goal is:
Daily backups (Mon, Tue, Wed, Thu) - 2 weeks retention
Weekly backup (Friday) - 4 weeks retention
Monthly backup (last weekly backup) on every month - 15 m onths retention
I've configured the short term protection for daily and weekly backups. Monthly backups are configured under long term protection. Daily and weekly backups are working as expected. However when it comes time for the Monthly, the DataSet copy jobs are failing.
As I understand it, DPM is expecting another drive to copy the weekly backup tape.
How I can achieve above goals ? Backup to disk is not an option.

Hi,
Any time DPM schedules a dataset copy job, you will need more than one tape drive, there is no way around that requirement.

Short, medium and long term planning in SNP

Hi,
can somebody explain me what Short, medium and long term planning mean in SNP?
Lets, say I have this scenario:
If I have a product with SNP horizon of 35 days, which means that the product is planned in SNP only after 35 days from today. Only PPDs deals with orders in these 35 days.
I have a 3 planning books
short term with 30 days from today
medium term with 7 months from today and
long term with 2 years from today.
When I say short, medium and long term planning in SNP what exactly happens in these ?? What do users usually do in these books?
SNP horizon is 35 days and the short term book is 30 days long, in which SNP does nothing. What's the use of this book?
Thanks.

When I say short, medium and long term planning in SNP what exactly happens in these ??
Nothing much from a technical stand point.
What do users usually do in these books?
Check the Time Bucket Profile for the different books. The short Term Book will be in days, the mid term in weeks and the long term in months/quarters etc. The different books allows users to see the keyfigures in different time-based aggregate level.
But if Heuristic is executed then behaviour will be different. Remember SNP Location Heuristic run uses the bucket of the data view to compute the Net Requirement and then try creating Receipts in each bucket within the time horizon of the data view using suitable master data. So if you run Location Heuristic in the short Term (daily) view then you will have many receipts one per day most likely. If you run in mid-term Weekly view then there are less number of receipts one receipt per week till 7 months. likewise for the long term view.
SNP horizon is 35 days and the short term book is 30 days long, in which SNP does nothing. What's the use of this book?
Maybe just to see the data. Location Heuristic run will not generate any new receipt.
Thanks,
Somnath
