I recently changed my back-up server over from Win2K to Linux. Due to Windows machines on my network, I have some that do back-ups via Samba -> ntfs-3g to a NTFS disk. What I have noticed is that Boinc (and it's client apps) hog the resources in spite of being started with "nice". A 10 GB back-up file takes 2 hours to write with Boinc running as opposed to about 6 minutes with Boinc suspended. Is this an issue with Boinc, Samba, ntfs-3g, or nice?
PS- I've gotten around the problem by having Boinc suspend for an hour while back-ups are scheduled.
