ok. point taken. Bonnie does create a very shallow tree for these files, but it's only a directory or two deep. What we really need is a Backuppc-specific benchmark. I don't suppose there's an easy way to take the storage engine out of backuppc, put it into some sort of test harness, and run some benchmarks with it? The only thing like this that I can conceive, would be to take a backup of the backuppc pool before a BackupPC_nightly run, time that run; then restore the copy of the pool onto a different filesystem type and try the same thing again. rather laborious, and not necessarily accurate. -- Carl Soderstrom Systems Administrator Real-Time Enterprises www.real-time.com ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
