Ok - I am looking to splitting job into smaller jobs and what I am seeing here is one policy backing up AD/SQL etc  without taking into account - application aware or indexing.

Hi Andrew,

it has been doing this for some time and before I got involved.

We have around 51 VMs total and about 4VMs experiencing slow backup.

Storage is Dell EqualLogic and EMC - VM in question is on Dell EqualLogic. Non-SSD

VM is on Datastore1

are all VMs are the same datastore ?

same SAN ?

what if you backup the VM, on it's own, and not along side others ?

just looking at long jobs.

VM14405 - EMC DS4
VM13383 - EMC DS1
VM10272 - EMC DS4
VM13375 - Dell  DS1
VM09235 - EMC DS2
 
 same SAN ? see Above

 what if you backup the VM, on it's own, and not along side others ?

All done in one policy - I am reviewing this (was done by my predecessor - not good practice)

I have started to split this per server and types.

Yes, that's what I'm saying run a test backup of these VMs are their own.

looks like datastore contention.

Gerald ConnollyCommented:
How is the SAN connected?

Those numbers seem very suspiciously rounded! 10MB/s & 5MB/s

Hi Andrew and Gerald,

got slight sidetracked last two weeks.

EMC is Fibre and Dell currently iScsi.
