Hi,
We need help or advise with the following.
Whe are looking for a new backup software solution
We have a trail version running Backup Exec 2014 on windows 2012 R2
We need:
Data 2 disk duplicate 2 tape
We have:
full flash SAN 10Gb controllers
10gb switches
2 New ESX hots
1 fyscal back-up server with SSD mirror and nearline SAS 7.2K raid 10 for our 18,2 TB disk storage
with 2x 10 GB controllers in a team.
Symantec is to slow and we do not know why.
Full backup to disk 13 hours 3,6 TB, Verify in a sepperate job 4 hours , Duplicate 8 hours (Tape unit TL2000 with utlrium 6 with SAS controller)
When i run a test job to disk with only virtual servers selected, connected to our pSphere server . It wil backup de vmdk files 3,2 TB in 6 hours.
job rate 160,5 MB/s
Veeam wil do the same in 3 hours and 45 minuts.rate max 384,1 MB/s processing rate 241 MB/s
What is wrong with Symantec config?
kind regards,
mvd

Are you backing up using SAN Transport or NBD?

How to be sure?
I connect ot the pSphere server and choose the vms
Virtual machine settings:

The job log will tell if SAN or NBD was used
04-02-2015 06:35 AM
Transport mode 'nbd' was used

OK so nbd is typcially slower than SAN, but SAN requires a connection between the disk storage that holds your VMware datastore and your Backup Exec media server - I suspect you do not have such a connection hence it is falling back to the slower transport type. You may want to read up on the SAN Transport option (both VMware and BackuP Exec documentation)
Note I have no idea how you confirm what Veeam has been doing in order to compare.

Is there a best practise voor de SAN soilution?
How to connect the backup server to the datastore?
Won't we get disk corrupution?
We have a Dell Compellet with 10 GB controllers 10 GB switches ESX host witk 10 GB controllers and a back-up server with 4 10GB controlers we are using 2 controllers in a team voor de network connection
thank you

Is there a best practise for a SAN mode setup?
I can not find it in the manual.
How to connect the back-up server to the data store?
Won't we get disk corruption whem Symantec and VMware are using the Datastore's ?
What will the performance do in the SAN transport mode?

Use this KB for configuring SAN-Transport based backups - http://www.symantec.com/business/support/index?page=content&id=TECH155831
Secondly, what throughput do you receive when all GRT options & Checkpoint Restart, Pre-scan options are disabled from the backup job ?
EDIT**
This KB could help as well - http://www.symantec.com/business/support/index?page=content&id=TECH185691

Thank you:
I found the same documents with google.
I did the test you requested but i won't go above 1,5 Gbps range 1 -1,5 Gbps

Hi,
Today:
I put a 2e broadcom dual 10gbps controller in our back-up server.
I connected the controllers with our 10 GB switches and set up an iscsi lun multi path IO.
Automount is disabled on the BE server
I created an iscsi lun with a test datastore. On this store i have 4 test VM's
I can see BE is pulling data over the iscsi lun but still to slow.
banthwith is not beeing used some small pieks to max 4 gbps but than again 1,4 gbps ethernet..
Please advice
SAN mode is juist a littlebit faster than NBD...
