search for: zfs_unmount_snap

I have to backup many filesystems, which are changing and machines are heavy loaded. The idea is to backup online - this should avoid I/O read operations from disks, data should go from cache. Now I''m using script that does snapshot and zfs send. I want to automate this operation and add new option to zfs send zfs send [-w sec ] [-i <snapshot>] <snapshot> for example
