You may need an unusually large amount of buffer space for TCP. The buffer space requirements for a TCP connection scale with the product of bandwidth and round trip time. If you use the central scheduler, you will have to allow for the time zone difference, and for the changes in time zone difference when Virginia transistions to or from daylight saving time and Qatar doesn't. You will need to assess the risk of missing backups because of connectivity problems. In the last few years there have been several incidents in which undersea cables serving Asia were damaged and whole countries had limited Internet bandwidth or no connectivity at all for periods measured in days.
