Extremely slow remote backups using backupexec 12.5

[bboyrandom]

Hi Everyone,

has anyone ever seen this before...

I have a few backup servers running 12.5 and none have the issue im about to mention except one..

I have a server backing itself up with an ultrium 3 drive.. this backups up at a very good rate.. but then it backs up 2 remote machines. 1 connected to the same physical switch and the other connected to a second switch which is uplinked via a 1gb connection.. none of these machines respond slow over the network.

When the remote backup starts on both these remote machines it is taking about 9 hours to do 7GB. the speed is displayed at 2.00MB/S

Any ideas?

All agents are on the correct version etc...

Many thanks

Hello,

Try copying some data about 2 to 3 GB back-n-forth from and check the speed

Hi there,

Could be just about anything. The first thing to ascertain is whether this is a new issue, or an old 1.
network settings/load is most likely the obvious culprit. Check your NICs on the servers in question, and make sure they are hard-coded to the fastest they can go (ie. 1GB FULL). Make sure that the speeds on the switch ports they are linked into correspond in speed, and are also hard-coded to that.
the time of your backups can be an issue...if you're starting your backups at a time when your server is doing maintenance (ie. Exchange/SQL etc), or under heavy user load, it can slow things down.
Also, if you have used LiveUpdate on your media server, but haven't pushed out the RAWS agent again (which would include updates for the agents)...if you have done an update, but haven't pushed RAWS out...do so.
What we can eliminate is a possible error with the drive. If you're getting good speeds locally, it is something else.

post the results here...

Laters!

Hi, I was actually just testing that as you replied :)

thanks for your help though as im guessing the switch has gone to half duplex and sending a file from the backup server to the remote is fast (copied a meg in less than a second) moving same file back took 35 seconds +

Thanks again

OK cool...if it helped, can you close off with the solution?
