Splitting the runs should help. You might even want to look at the directory contents and split at the subdirectory level. Other than sheer voulme, the things that can make rsync slow are very large numbers of files where handling the directory listing becomes cumbersone, and very large files with changes where the server has to reconstruct a full copy with bits from the old and bits from the transfer. An incremental against a fairly recent full should run about as fast as both systems can read the directory contents, though. -- Les Mikesell lesmikes...@gmail.com ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
