Backup Exec running slow

Hi, help needed on speeding things up.

current set up

NT4 backup exec 8.5 (all service packs/options available) (the server isnt doing anything other than backing up at the time.

backup exec is based on the exchange server,
and backs up the edb files with agent then also does a mailbox backup.


then it backs up a few other servers of general data(windows 2000). and there is a second DLT which has jobs backing up sql data (first bak files then the c drive its self.


I know mailbox back up is slow.

but jobs are getting very long with out a great change in the amount of data.

data rates have changed from 300mb to 40mb  and i cant see why,

do you have any tips/best practice ideas etc,

im going to recreate all the jobs, but would like to know what you think some changes i could make /try before hand


Thank you

we do use Norton navce   but even tried disabling this over night    no change.

for ref.

data rates

a remote windows 2000 server   40mb


a remote sql server win2000   130mb

local data       140 mb

a remote nt 4 server   100mb

all of these used to be well over 200mb  and i cant think of anything that has changed.

Have you ever defragged the local file system to speed up writing to the B/E DB or the target systems?

Are you geting low on disk space on the backup machine?

Are you seeing any errors in your event logs?

Have you applied any system updates to the backup machine that correspond to the slowdown?

no erros, disk space fine
nothing altered (other than normal hotfixes)

and none of servers need defragging

here's an area where you have to corrollate patches with problems
Windows Update doesn't know about your apps
If you've done a blind windows update and you're suddenly experiencing a problem, often your onloy recourse id to re-install the application
 
>and none of servers need defragging
golly
research shows that defragging windoze servers can provide performance benefits up to %40, especially on SQLserver
as NT doesn't have a native defrag utility, that's a pretty sweeping statement

If your network throughput is generally a LOT lower than what you see backing up a local file, I'd also look for an ethernet speed/duplex mismatch on the backup server.

Just a thought - DLT data transfer rates drop as the error rate climbs. Could just be dirty heads...

Having said that, the drive should request a cleaning tape if the error rates exceed a threshold. Has the cleaning tape expired? Perhaps old media?

Try a new cleaning tape and new tape.

My Veritas Bkp has slowed to a crawl too over the last week.... Could it be the latest Symantec Event handler? you know, the one that fixed the memory leaks and server reboots?

The through-put on Backup Exec 8.5 plunged from >300 MB/Min to 8 MB/min. Nothing showed up in The Event Viewer on any of the servers not did the switch monitoring software show any bottlenecks or problems on the netework. (This was over the weekend) I went ahead and rebooted the backup server as well as the file server and restarted the full backup. I checked back later and still had a through-put of 8 MB/min. As a last resort, I rebooted the two network switches (3COM 4400 SuperStack 3) - waited 15 minutes then restarted a backup job. Problem solved - through-put was 402 MB/min.
