Via EPIA EN 1.2GHz processor, 512MB RAM, single 750GB PATA hard drive backs up 4 different servers, with a total data storage of ~600GB: 2 x ~250GB servers, the remaining servers with less than 50GB between them. Full backups weekly, incrementals daily. Oh, and this is over 100Mbit. Everybody freaks out about the amount of RAM: they tell me I need more for better speed. However, I've watched vmstat throughout the process and the swap BI/BO remains at 0. However, this is about the limit of the box. On the big servers the fulls take about 600 minutes to complete. The incrementals takes less than an hour. All told, we get it all done easily in the 12-hour backup window, even if they both run at the same time. Beyond this capacity, you'd probably be able to do it if you more carefully managed which servers do fulls at what time. I don't need the hassle: at this location, I have two BackupPC servers so that I don't have to. Besides, at the time I built these, 750GB drives were the largest you could get, and I preferred using separate servers rather than going to an internal RAID array.
