|We do use an incremental backup strategy but as we add users to our backup as we startup new remote sites for our business we are wondering what we can do to improve the performance of our backups? We backup daily and currently have around 10 users. Is a new more powerful server going to help us? Or should we spend our money on more bandwidth? Most uploads from remote clients seem to hover around 48-52kbps. Most of our users are on residential cable broadband.|
A newer, more powerful server won't help with this however since it's a network issue, not a server horsepower issue.
As I see it, the weak link in your setup is of course the connections of other sites and/or users. You have to know very well that residential broadband is not conducive to high bandwidth. Most (if not all) ISP's oversubscribe their segments in order to make money which cuts into bandwidth. Also, being residential, you have to fight with the movie/software/music pirates running their P-to-P software.
If it were me, when at all possible I would upgrade to business class broadband as vs the residential. Since it's more expensive, you have less of the aforementioned problems to deal with (meaning more bandwidth) and, you can normally get packages with higher upload rates. That's the issue you seem to be having. It's not that your location isn't downloading fast enough, it's that the point of origin is very limited for upload rate.
So, I would start by looking at getting packages that offer higher upload bandwidth.
You might want to also take a look at putting tape backup devices at all remote locations and then taking the tape backups offsite for safety and security (ie: in case of fire or some other disaster).
