Looking for a free backup solution

hi,

if you are running windows 2003 then best would be to use it for backups on each server in question and then using robocopy you can copy the files over to the desired location.

Verify if the time taken for the backup to complete has been due to increase in the size of data or some network related changes.

I would certainly say that for 80 Gigs of data if this is taking almost 15 hours then i would certainly check if there are any issues with the network. Have you applied windows services packs recently. As that has caused network issues and to resolve this first thing to do is update the network card drivers and then try.

please post back if you have noticed the backup slowing down on a specific machine.

Hi

https://www.experts-exchange.com/questions/24024584/back-up-solution.html?cid=238&anchorAnswerId=23293561#a23293561

it's a perfect solution for u

80GB's in 15 Hours works out at 1.5MB/second which certainly makes it look like its your network thats the bottleneck, have you thought about the topology of your network and simultaneous dataflows?

Its obvious that there are two main ways of reducing the time a backup takes:
1) Reduce all the bottlenecks in the datapath and improve the end-2-end time
  or
2) Reduce the amount of data you are backing up. (differentials, incrementals, incrementals for ever and synthetics)

Tell us more about your network

I have four dell 2008 servers, and the rest of our servers are 2003 custom built servers.
We have four cisco catalyst 2960 switches that are network is going through.

How is your networked wired and how does each server get backed up? ie where does the 80GB come from?

The 80 gb comes from a file server that is backed up across the network to another fileserver using acronis.

I have noticed a big difference since I changed the backup to run a differential it only took an hour and a half.

The server that the data comes from is plugged into one of the cisco switches.  The server the data goes to is plugged into a switch that is uplinked through two other linksys switches.  

server to 100mb switch to 10mb switch to 10mb switch to 10 mb switch server

Any reason for the chain of switches? are there some long links in there somewhere?

An obvious way of decreasing your backup window is to replace your current switches with Gigabit ones (this might also involve GbE cards for the servers) cut out as many hops as possible and you could as i said before get it down to 30 minutes.

I believe the problem is related to using faster switches with slower ones.
I tried the Synback and it ran longer and had to be stopped as it was causing slowness on the server during production.

I started the backup at 7pm the previous night and it still wasn't finished.

Of course there is going to be some latency involved with your switch chain, but that latency is dwarfed by the real problem which is your end-to-end throughput is governed by the slowest link, in this case 10Megabits/second!

I gave you some throughput numbers in an earlier post of 80GBytes over 15 hours = 1.5MBytes/sec, it actually works out at just under 12Mbits/sec! Does that sound familiar?

The only way to get a faster backup, is to either backup less data or to improve the end-to-end flow rate! (ie by going to 1GbE or faster)

Hi
can u try the following:
compress ur data manualy to one .zip file and move it either FTP or SCP (secure Copy) or even normal copy to the server through ur netwrok >>>>

and check required time consumed ???

send results ??

again: be sure u are copying only one huge .zip file >> ok ?

Hi

plz advise status here?
is it solved
???

BR

for the moment
