Well this is probably relevant - home FTP server for backups?
I have a dual sossaman box running WCG. Not a lot of horsepower but it is a fun little 2P box :D Anyway, I have some friends who have local backups of their stuff but like the idea of having offsite backup. So we looked into the typical Carbonite, etc, but then I got the idea that maybe I should look into hosting my very own FTP server they could then back up to. Saves them money, it could be fun to do, I could use it for other things, and hey, the box is running already anyway :D They would run their backups at night so it won't affect my internet or theirs too much... my download rate is far faster than their uploads combined, so that's a non-issue.
So... ideas of how to go about this? The box currently has XP Pro but that's just what I had lying around when I set it up. I could go with something else.
Also, I have a dynamic IP as is typical, so I'd need some sort of dynamic DNS service I guess. There used to be some free ones but not sure if they are or not or which is recommended, or whatever. So info for that would be helpful too.
Danke!
