It definitely sounds like something else is broken. Taking 5 minutes to read a single relatively short log file should be near instantaneous with or without NFS. I have no problems running NFS server on a *very* low end NAS (arm-based device running at 800MHz with 64MB RAM) to and 8 year old client (P4 2.5GHz, single core, 2GB RAM) where BackupPC itself runs. I don't notice any lags on looking at log files beyond what one would expect to bring up a web page. > Or, on a completely attack vector, can all of the BackupPC > operations be performed from a shell? I almost never access via the GUI. In fact, I have several BackupPC implementations that don't even have the web interface installed (they run BackupPC on a plug computer and I didn't have room on the 512MB flash to put apache). ------------------------------------------------------------------------------ Benefiting from Server Virtualization: Beyond Initial Workload Consolidation -- Increasing the use of server virtualization is a top priority.Virtualization can reduce costs, simplify management, and improve application availability and disaster protection.
