I have a vpn between two 2M broadband connections. I want one of my sites to hold backup data but this means I need to move about 30G-50G of data. This will take hours/days I'm currently transfer a 30G file at a rate of 800bytes/sec and in 15hrs has transfers 1.7G. What is the best solution?

Thanks, Mike

The best solution would be:  a high-bandwidth private line between the 2 locations so that a VPN wouldn't be necessary. But if these locations are farther apart your choices are more limited.  If you have the budget, a pair of "WAN accelerator" appliances could increase your throughput significantly.  If possible, doing a daily differential backup would be much preferred - typical daily data changes might be as low as 3-5% of the total amount of data.

  If you have to work with your current 2M connections & must use VPN:
- What encryption are you using?  3DES can be extremely inefficient unless you're doing the encryption via fast hardware; AES would be preferred if this is an option, especially if done in hardware.
- Do daily differential backups + 1 weekly full backup, if feasible
- Consider buying a pair of WAN accelerators
- The actual transfer method can greatly affect your throughput.  eg, copying to/from Windows shares is extremely inefficent compared to an FTP or even HTTP transfer.
- In both the source & target systems, NICs with capabilities such as TCP offload would be much preferred.

Good points raised. Will look into a couple of them particularly the WAN accelerators and diff backups.

Thanks
