I wonder whether there is something wrong with your setup, particularly on the Windows machine. I backup a WinXP Home partition containing 110,000+ files totaling just under 27GB (i.e. about 3x as many files as you consuming a little more diskspace) The client is low-end, *old*, and slow -- 4+ year old, single core celeron 1.6GHz with 2GB ram. The server is non-dedicated and even older - 8 year old, Pentium4 non-hyper threaded, single core, 2.8GHz with 3GB memory. The network connection is a shared Linksys wireless G router. Storage is via NFS over a 100mbps wired port on the Linksys to a low-end consumer NAS (DNS-323). Clearly, my hardware is about as old and low-end as one can get ;) I use rsyncd with cygwin 1.5 (or 1.7) with a stock BackupPC install. Yet, incremental backups take about 15-20 min and fulls take about 70 minutes. So unless you are changing a large fraction of the files and disc space between fulls, I would suggest that there is a problem with your setup. ------------------------------------------------------------------------------ _______________________________________________ BackupPC-users mailing list [email protected] List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
