Even with 4.5 million files, which is rather large, it should not be more than 5 or 10 minutes before Bacula finds the first file in an incremental backup and begins writing it to tape (assuming you are not using spooling). I suspect that you have an *extremely* slow NAS or some other major bottleneck (network, NFS, ...). It seems to me that you not only have something that has a bottleneck, but it has a monsterous bottleneck that I even have difficulties imagining unless you are talking about another software product or trying to do a restore, which for 4.5 million files could be very time consuming. Bacula simply reads the filesystem directories and writes out files that need backing up. There is no preliminary time intensive setup before Bacula begins working as in some other programs. > > > > I've seen mention here on the list of others backing up multi-terabyte > servers - I'm looking for suggestions on how to optimize and speed up > the backup process. > > > > Thanks! > > > > Alan > > > > > > ---- > > Alan Davis > > Senior Architect > > Ruckus Network, Inc. > > 703.464.6578 (o) > > 410.365.7175 (m) > > [EMAIL PROTECTED] > > alancdavis AIM > > > > > > ------------------------------------------------------------------------- Take Surveys.
