I just checked our existing backups repositories. The backup files are VMware image backup files, daily ones are smaller, weekly/GFS larger. But the are not millions of smaller files. For primary backup there are ~25.000 files in 68 TB of a 100 TB share, for a new repository with a 400 TB fs this would result in ~150.000 files. For the the secondary copy repository I see 3000 files in a 100 TB share. This would there result in ~200.000 files in a 700 TB repository. Is there any formula to calculate the memory requirement for a number of files? Ralf
