Hello,

Optimized duplications from Production Storage server to DR storage server via SLP fail with status 84, but backups to both Storage Pools complete successfully. 

 

Job Details:

21/11/2011 14:22:51 - Critical bpdm(pid=5672) sts_copy_extent failed: error 2060029 authorization failure 
21/11/2011 14:22:51 - Critical bpdm(pid=5672) image copy failed: error 2060029: authorization failure

At the same time i saw that in one of Puredisk`s nodes (SPC)  the Q-Process faild and after rerun he dont starting.

 By this site i followed to this page:

and I saw that in pdwfe.log this error:  Cannot create PDDO Task (id: 51000) job, Storagepool FULL

so by the site that i worte here, i clear the /var/log (was 70%) and restart the pd.

MSDO & PureDisk

Hello everybody!!

 

Do you know what is exactly the difference between MSDO and PDDO? I read that in the future PureDisk won't be supported by Symantec and some articles about how to migrate PDDO to MSDO... I have this doubt because I was working with a PureDisk environment but some TSE call servers MSDP Server.... so I'm confused... do you have any idea?

backups jobs always getting cache hits: 0 (0.0%)

I need a solution

Hi there,

I am experiencing this problem with all backup jobs, no matter if they are using server deduplication or client-side deduplication

Dedup seems ok with very good ratios but cache hits is always 0.

Here you are an example:

01/17/2013 07:15:33 - Info bak002 (pid=19972) StorageServer=PureDisk:bak002; Report=PDDO Stats for (bak002): scanned: 153346694 KB, CR sent: 617422 KB, CR sent over FC: 0 KB, dedup: 99.6%, cache hits: 0 (0.0%)

Surely is a configuration problems as it happens in all my clients but till now I haven't found the cause

My environment:

  • 1 Master 7.5.0.4 Linux
  • 1 Media 7.5.0.4 Linux
  • Clients Windows/Solaris/linux 7.5.0.4

Any idea?

Best Regards

fakeFPCheck reports corruption while reclaiming deduplication space

I need a solution

I am reclaiming deduplication storage space manually on a 5200 appliance. I am following the process in TECH180659.

I see a lot of these type of messages:

January 21 08:58:24 INFO [1082194240]: fakeFPCheck: DO 53c8979cafabfcc54c82cf7900fa465a is corrupt

And running the garbage collector doesn't seem to clean them up as they show up again the next passof running CR queue processing ( /usr/openv/pdde/pdcr/bin/crcontrol --processqueue).

Is there some way to clean up these corrupt fragments and reclaim the storage space?

Thanks,
Wayne

=> the only workaround we found is to reboot to PureDisk server ; after that, the jobs are launched correctly

Is it a kown issue ? if yes is there any fix for that ?

Thanks to all by advance for your help.

Obtaining protected data size with PureDisk

I have a PureDisk environment running 6.6.0.3, without a central SPA, and need to be able to obtain the front-end protected size of the data that I am backing up. If I had a SPA with central reporting enabled, then I could run teh Enterprise License report, but since I do not have central reporting enabled, I don't seem to have the report available.

 

How do I determine how much front-end data I am protecting?

SLP duplication jobs

February 25, 2013, 12:02 pm

I need a solution

Hello. Had a server where the duplication jobs (per the SLP) were not finishing or erroring out. I have a ticket open for this, but I generally have better luck / faster responses with the forums -

After cancelling out these 'hung' jobs, I restarted services on media / master, etc. I am currently pointing this client directly to the storage unit where backup jobs are running fine. No SLP currently.

My question -

C:\PROGRA~1\Veritas\NetBackup\bin\admincmd>nbstlutil stlilist -image_incomplete

V7.5.0 I ahfs1_1361257201 ahslp 2
V7.5.0 C ahmedia-hcart3-robot-tld-2 1 1
V7.5.0 I ahfs1_1361343601 ahslp 2
V7.5.0 C ahmedia-hcart3-robot-tld-2 1 1
V7.5.0 I ahfs1_1361430000 ahslp 2
V7.5.0 C ahmedia-hcart3-robot-tld-2 1 1

These images are still awating duplication. Seems I've read that they will eventually catch up? If so, does it matter if this client is pointing towards the SLP or the storage unit? Does the client have to have the SLP active / specified in the policy in order for these images to catch up?

Hello,

 

Netbackup permit to realize the following backup strategy :

  • Weekly full backup done on tape
  • Incremental backup done on a dedup pool

 

I have several questions about this :

Does Netbackup can find modified files between full backup on tape and first incremental backup deduplicated ?

A Full backup deduplicated is not necessary ?

 

Thanks for your answers.

Hi ALL,

we are working on using deduplication technology in our environment but want to have below things clear:Just the basic idea?

  1. Before NBU 7.x,How do we do deduplication? we use symantec netbackup pure disk?
  2. Symantec NetBackup PureDisk is a product that provides a complete backup and deduplication environment. It can be used as a stand-alone (PureDisk writes data to the storage pools) or as a back-end for NetBackup. How it is use as standalone and as backend?
  3. now in 7.1 we have MSDP.This is also using Pure disk?
  4. What is this MSDP?And this PDDO?

NBU dimensioning puredisk DSU

I need a solution

Good morning all,

  today i need to dimension a new MEDIA for a bunch of servers that are going to be added to the one.

I'm talking of 10 servers someone with SAP db, below detailed:

2.35T of raw space (maximum disk capacity summed for all the servers).

370G Sap db+Arch logs (actually running).

Around (foresight) 500G of new DB (Sharepoint installation for Documentum)

 

Sap db+arch logs runs everyday.

Disks backup 1Full+6inc.

Sharepoint will run too everyday (i don't know if it will use mssql process or another specific one that can use inc+full).

Retention 2Weeks for all the backups.

I'm thinking about initial 6T of /DSU (PUREDISK with dedup) in order to stay quite for some time, but i would like to have a real and precise measrument to calculate it prior to stay far from reality.

 

Thank you.

 

Kind Regards,

NTFS cluster blocking factor for MSDP database and MSDP data volumes?

Hi Forum - I've read elsewhere that is is recommended to format the NFTS volumes that will be used to house the MSDP database and MSDP data with a cluster size of 64 KB (i.e. 128 traditional 512 byte sectors).

However if if look at a slightly populated MSDP server, I see most files are less than 64 KB.

Does anyone have an opinion on this?
