  You can do both.  I keep daily snapshots, and I also make snapshots called
  "@inc30" for important datasets every 30 minutes.  The basic idea:

    zfs list -d 3 -Ho name,mountpoint -t filesystem |
        while read dataset mountpoint
        do
            skip unmounted or redundant datasets
            skip top-level pools like "tank"
            snapshot="${dataset}@inc30"

            zfs diff -H "$snapshot" 2> /dev/null |
                grep '^[+M]' |
                remove crap like cache-files ... > flist

            use cpio/tar/whatever to copy flist elsewhere
            rm flist
            destroy $snapshot
            re-create $snapshot
        done

   When I mangle a file, it's usually something I've created in the last
   hour or two, so daily snaps don't help.  After a few months, I roll
   the 30-minute backups into one daily backup.
