Need Suggestion in configuring SLP

Hi All,

We are using NBU 7.5.0.6 on w2k8 machine, attached to 2 LTO-5 tape Drives, and we are backuing up 17 TB data(not completing in weekends). so now i had 26 TB space on Dell MD 3000 storage box(connected to master/media server by using SAS connectivity). i want to know whether can i configure primary copy to Disk(with 15 days retention) & secondary copy to Tapes(with 3 months retention) with out having any extra licence? when i try to configure SLP i'm not able to select the Disk which is attached with SAS connectivity, so could any one help me on this.

Hi John

 

I suspect you used a basic disk storage unit for the disk. Basic disk is not supported with an SLP, must use advanced disk.

Note on creating the advanced disk storage unit.

You need an OpenVision to see the truth about Backups. Restores are a plus. But that's just Semantics ;)

ITs easy :)

so you did configured the SAS disk as Basic disk storage unit it seems...

Basic disk storage unit is not supported with SLP, you need to configure it as Advanced disk.

but if you are in traditional license model you need additional license to configure the advanced disk..

alternate options is to

1)configure the DSSU(disk staging storage unit)

use the staging scheudle in the basic disk and stage them to tape

2) configure the basic disk storage unit for backup and use Vault or manual duplication(scripting) to stage them to disk

 

I first preferce it with Advanced disk... if its not possible due to license issues i will go with DSSU. ( since it will make sure the images are duplicated to tape before expiring it from disk)

Hi Riaan/Nagalla,

Thanks for your posts.

Yes i configured STU as Basic Disk, i had seen the documents posted by Riaan.

1)configure the DSSU(disk staging storage unit)

use the staging scheudle in the basic disk and stage them to tape

Nagalla i tried to follow the same procedure but, i think so the retention will calculate as same for both copies right ? as per my company policy we need to retain the data for 3 months, but while creating Disk STU it wont allow me to select the different retention for only 15 days for primary copy right ? it will condiser the retention in schedule level?

Rather use the SLP if you have the licenses which I assume you do.

Ok Riaan,

small conformation, we had 7.5 NBU licence, does it includes Advanced Disk NetBackup Licenses ? or else how can i check it from the server with existing Licences?

Riaan.Badenhorst's picture

check your licensed features via the gui or bpminlicense -verbose

you do not have advance disk entitlement.

sync with sales rep to provide data protection optimization option eval key (confirm with them if eval is available)

evaluate with keys (services must be restarted after key is added) features you wish meets your requirement

 

 Cheers !!!

Hi sparrow,

Thanks for your conformation, i will try to contact sales reprens,

Hi,

 

CJS is correct.

John,

I still stick with advance disk and SLP , but if you have issues with lincense, 

you can achieve your requierment with Basic disk may be more than that..

configure your backups to Basic disk and keep the retenction as 3 Months and use the disk staging to tape.

with this netbackup image tries to keep the data 3 months in disk and duplicate to tape also keeps there for 3 months.

if basic disk reaches the high water mark it will expire the data form disk(if duplicated) and makes the space for next backup jobs.

since you have 26 TB Disk space..you can only have the images on disk for only 1 full backup and incr (since full backup is 17 TB ..and can not have the 2 full backup(17X2=34 TB) 

so keeping the data on disk for 15 days( 2 full bakups) is not possible unless you have deduplication.

--- bottom line---

if your basic disk reached high water mark in 15 days it will expire the data on disk and move forward...  applies the same even if it reaches in 2 days or 2 months..

1. we are backuing up 17 TB data
2. i had 26 TB space
3. can i configure primary copy to Disk(with 15 days retention)
 

This will not work - not even with Advanced disk and SLP.

Weekly backup of 17 TB:
Day 1:   17 TB
Day 8:   17 TB
Day 15: 17 TB 

This does not include any incrementals. 
How do you want to fit this onto 26 TB without dedupe?
You should have at least enough space for 2 full backups. Advanced or basic disk.

Hi Marianne,

it will have Incremnetals also in daily basis, as per my plan to set the retention only for 1 week or expire after duplication in SLP.

Marianne's picture

Adding Incrementals to the mix will increase space requirements.
You will need space for at leat 2 fulls as well as 7 days worth of Incrementals.
Having space for only one Full is not a good idea.

It seems you need to approach your management for dedupe licensing.
Or purchase more storage.

As explained previously - you cannot use SLP with Basic Disk. 
You need Advanced Disk or Media Server Dedupe.

Backup window should not be your only motivation to move to Disk Storage for backup.
If backup to tape does not complete within the backup window, you need to first of all find out where the bottleneck is. Tape is hardly ever the problem.
In most cases, the reason is slow read speed from the client disk and network congestion.
Disk backup is not going to solve this.

LTO5 can do way more than 100MB/sec.

This means that one tape drive averaging 100MB/sec can backup +- 6 Gb/min.
That is 360 GB/hour, 8.6TB/24 hour.
So, your 2 LTO5 tape drives are more than capable of backing up 17 TB and much more over a weekend.
You are just not getting the data fast enough to the media server(s).

You will most probably have the same problem with disk backup.

Use VAULT to duplicate images, it will not cost you anything more because you already have the license.

He has Enterprise Vault Application agent license, not NetBackup Vault:

NetBackup Vault is a separate licensed opion.
