When I'm doing backups/dumps of ZFS filesystems (with whatever tool), I use snapshots. So, suppose I have the following datasets: /etc /usr /usr/local /var I'll snapshot them and back up /etc/.zfs/snapshot/snapname/ /usr/.zfs/snapshot/snapname/ /usr/local/.zfs/snapshot/snapname/ /var/.zfs/snapshot/snapname/ Then I'll get the same directory structure when restoring. Any idea how to easily remove the .zfs/snap and go back to the original tree? I tried writing a few lines of script, but I found out that's not so easy (due to directories which must overlap, spaces in file names, etc...). Any hint? bye & Thanks av.
