But ... NBU (at least version 6.0) attempts to estimate the
size of the backup and make suer there is enough room on the DSSU to
handle it. What happens when the free space reported by ZFS isn't
really the free space ?
We are using NBU DSSU against both UFS and ZFS (but not
against VxFS) and have not noticed any FS related performance
limitations. The clients and the network are all slower.
