Storage solution for backup jobs

Created: 29 Sep 2013 | 8 comments

Hello Team,

I have the licenses for symantec backup exec to take the backups but i am stuck with the storage option.

Presently we have

1)HP MSL2024 1 LTO-4 Ultrium 1760 SAS Tape Library (10 tapes each with 1.6TB storage)

2)HP Storage Works Network Storage System ( Used as B2D storage)  -- 5 TB

Could you please suggest me a storage solution ,taking into consideration the above 2 options.

it would be greatful ,if you can suggest  a new solution.

My requirements :

1) Make backup jobs run to tapes ;exchange backups to disks;

2)Archive the backups of important backups.

2)we also need disaster recovery storage option

 

Thanks in advance .

1) Make backup jobs run to tapes ;exchange backups to disks;

Create your backup jobs and target them to your tape libray.

Create a disk storage on your NAS and target your Exchange backup job to this storage.

2)Archive the backups of important backups.

Add a duplicate stage to your Exchange backup job and target this to your tape library.

2)we also need disaster recovery storage option

You can use either the NAS or your tape for recovery.  Make sure you backup at least the entire C: drive including the system state and make sure the SDR light is on in your backup selection screen.

Thanks pkh .

Create a disk storage on your NAS and target your Exchange backup job to this storage.

We Presently have Dell EMC CX300 Storage Array.Can these be used a B2D folder and target the Exchange backup jobs to this storage ? If yes ,how to do it ?

"Add a duplicate stage to your Exchange backup job and target this to your tape library."

How and where to create a duplicate stage ?

Actually i am new this storage arrays.It would be greatful if you could help me understanding this storage devices.

Thanks in advance.

...first thing's first...check the BE version's HCL you're using to make sure that the array is supported.

Since that uses FC anyway, you should be able to present disks to the media server and then group those disks into 1 big LUN if need-be. Then download b2dtest.exe and run this against the LUN/s to make sure it is going to be supported.

Create a B2D on the media server, and then target your jobs to this. For the duplicate job to tape, you need to add a stage in. Check the TN below if you don't know how to do this:

The CX300 is an old array, and should be 2GB from what I can remember, so connectivity-wise you're not going to get very fast speeds during backups. But, if this is all you have, then it should work until you can replace this with something newer and more powerful.

Thanks!

Your disk can be used for disk storage.

For your other questions, I would suggest that you read the Admin Guide first.  You can download it here

Which one would be the best .. SAN or NAS .

Does NAS support the same speeds as SAN ?

Would it be best practice to use NAS as B2D disk for storage ?

I'd suggest doing a bit of digging of your own around SAN vs. NAS. But here is a 100000 foot look:

1. SAN - up to 16GB now using fibre vs. NAS using 10Gbe network.

2. SAN is faster, but more costly. You'd need additional hardware like FC cards for all servers etc.

3. Most SAN and NAS devices use similar types of drives, ie. 10K, 15K, 7.2K, so drive types are pretty common.

4. NAS using iSCSI would be a good idea when using a NAS as a B2D. It's going to get around all the configuration/authentication issues you might receive otherwise.

Thanks!

Hello CraigV,

We have a total of 20 Servers. Applications include

1) Exchange Server         -- now 250-300GB

2) 3 File Servers               -- now 800+600 GB

3) 2 SQL Server                 -- 150 GB    

4) Active Directory Servers -- 150 GB  

Sizes mentioned are approximate. If we take a full backup weekly we may need 3TB storage.

We have the below storage

1) Dell EMC CX 300 Series Storage Array  

          In this first 5 slots are occupied and have room for 10 more drives.

2) HP MSL2024 1 LTO-4 Ultrium 1760 SAS Tape Library    -- 10 tapes each with 1.6TB

          In this there is room for 12 more tapes

3) HP Storage Works Network Storage System                --- 5TB

       -- Using this as B2D disk.

We want to include the existing storage and decide on a storage strategy.

If possible we can go for upgrades/additions on the existing ones

 New ones mean adding tapes in the library – this can be possible.

 I wanted B2D disks for the Exchange backup jobs.so I suggested ATA/SATA drives for Dell EMC. Is it possible to add SATA drives and connect it to our Backup server and make it online in LAN? What you think,  can this be possible?

While i was going through the Dell EMC CX series initial config guide, i found below and thought of using this option .Can this be put in to action in our scenario ?

"Backup-to-disk

Backup-to-disk is sequential in nature and typically uses medium (64 KB) to large (256 KB) I/O

sizes. For these types of applications use ATA or SATA-II drives, although you can use Fibre

Channel drives. To calculate the number of Fibre Channel drives use the “rule-of-thumb” values

in EMC Dell/EMC CX Series Best Practices for Fibre Channel Storage.

For ATA or SATA-II drives use RAID 3 4+1 or 8+1. "

Based on the above number of servers and storage availability ,could you please suggest me in deciding on storage.

Thanks again .

Hi,

 

1. Well, as long as the media server has connectivity to the SAN, you can put in new drives and present the LUN/s to the media server for use as a B2D target.

2. I've used normal SATA drives in an Iomega NAS presented via iSCSI, so FC drives are not the only drives and there are other cheaper options. FC drives are going to cost you big time.

You need to check out the cost of those FC drives as they are likely to be very high. Also consider using the CX as it means you're possibly going to be stopping the use of the HP B2D which might be worth looking at upgrading, if possible.

Thanks!
