I have a home network with a cheap-o little router with a development server and a few devices hooked up to it. I am finding that backups of my server are taking FOREVER (a week for 60gb) running backups renders my internet connection useless from any other box int he house.

I have maxed out the pipe to my house from the ISP (10down, 3up), but is there a way for me to test and see if my router is bottlenecking anything?

I feel like 60gb backups shouldn't take this long so any help would be great!

This question came from our site for system and network administrators.

    
are the back-ups occuring locally on your LAN or are you backing up to a server off site (internet, WAN, VPN etc)? –  Xantec Dec 23 '10 at 21:41

You already know that you've maxed out your bandwidth, so you know that your router isn't bottlenecking. If it was, you'd be unable to max out the bandwidth.

Assuming that you're really getting 3 megabit per second up, 60 gigaBYTES will take 45.5 hours, assuming no overhead losses. So yeah, a week for a backup is reasonable. Are you just spitting files out there, or could you look into doing some sort of compression before backing up? And/or doing some sort of differential backups for subsequent runs.

well, 44.4 (repeating) hours assuming 0 overhead and a sustained top speed, but who's counting: (60000000/(3000/8))/3600 –  Xantec Dec 23 '10 at 21:37
    
1024 Mbytes in a GByte –  mfinni Dec 24 '10 at 12:08
