Hi ,

We have only three servers in our company. All are HP proliant ML150. One of them is having HP storageworks Ultrium 920 backup device. We are doing backup using Symantec backup Exec 11d.
Now, the issue is its takes ages to backup only 450GB of data. 16 to 17 hours. Can you believe it?
I have no idea why it is too slow.
Could someone please help me with this. I can provide more details if anyone willing to help me.

Thanks,
Pankaj

you could try  browsing through the job history/log and see which agent is taking all of the time to back up. it should give you the time each section started and finished backing up. this should give you a starting point

Optimizing Cloud Backup for Low Bandwidth

With cloud storage prices going down a growing number of SMBs start to use it for backup storage. Unfortunately, business data volume rarely fits the average Internet speed. This article provides an overview of main Internet speed challenges and reveals backup best practices.

yes there is one specific server which takes more that 9 hours to backup. This server is running most of our core applications and processes though the data on the server is not that large.

Servers:

Server1 - Anti virus server, SQL, Sharepoint, File and print
Server2 - DHCP, DNS, Backup EXec, Exchange
Server3 - SQL, IBIRS, TIMS, etc (Core applications)

i hope this makes sense :-)

Servers 3 takes around 9 to 10 hours atlease while other 2 take only comparatively very low time.
I can send you details Job history if you want.

Server three has a gigabit NIC?  

Try copying a file between server 3 and the BE server, see what throughput is on that.

Okay that's not great but the link speed isn't the issue.  BTW there's a nice little program called DUMeter (http://www.dumeter.com/) that has a nice bandwidth graph, you could monitor bandwidth during the backup as well as CPU on Server 3 and probably get some clues.

I'm guessing your CPU is overloaded during backup?  It's unlikely anyone can just say "oh, it must be <whatever>" with something like this so trying to help troubleshoot. :)  However NeilDBlackburn may have more to say since he has a recently solved similar problem. :)

so you mean to say SQL shceduled processes are causing this delay? There are only 3 or 4 processes running on SQL for few minutes. I was not accepting them to cuase any issue, do they?

that may well be your problem then, can you temporarily  stop the scheduled tasks and try the backup, as datedman says it sounds like you are seriously overloading your CPU during the backup

They only run a few minutes?

I'd watch the server during backup, check CPU use or maybe something disk-intensive is happening?

does your AV software run a daily scan? if it does is it during the backup window?

humm, All right I will watch the server and CPU usage for couple of days and will let you know guys. I believe I just need to monitor server3 which is taking while to backup, am i right?

Thanks for your help.

Actually you might want to try running that portion of the backup during other hours and see what's going on then?

I have a fileserver with over 3 milion files that takes over 6 hours to backup to a disk in Backup Exec. This is actually caused by the amount of files being backuped. Has nothing to do with network bandwith, it the amount of files that is the problem. I divided my backup in three jobs, they now run in parallel and this cut the backup time almost 50%.

Could you check the backup log and see how many files have been backuped during the 9 hours ?
Do you use Backup Exec SQL agnets to backup the database ?
How about compression ? are you using hardware and software ?

Yes we do use Backup Exec SQL agents to backup the database.
We use Hardware compression (if available , otherwise none).

I am interested in how do you run parallel backup and how do you divide backup in three diff jobs. Do you use two separete hardware to run parallel job.

Thanks for your help and looking into this issue
