From "man fstab"...
       The  fifth  field,  (fs_freq),  is  used  for  these filesystems by the
       dump(8) command to determine which filesystems need to be  dumped.   If
       the  fifth  field  is not present, a value of zero is returned and dump
       will assume that the filesystem does not need to be dumped.

       The sixth field, (fs_passno), is used by the fsck(8) program to  deter-
       mine the order in which filesystem checks are done at reboot time.  The
       root filesystem should be specified with a fs_passno of  1,  and  other
       filesystems  should  have a fs_passno of 2.  Filesystems within a drive
       will be checked sequentially, but filesystems on different drives  will
       be  checked  at  the  same time to utilize parallelism available in the
       hardware.  If the sixth field is not present or zero, a value  of  zero
       is  returned  and fsck will assume that the filesystem does not need to
       be checked.

The first 0 field sets that filesystem to not be "dumped" or backed up with the dump command.

The second 0 is the order to be checked with fsck at boot. The root filesystem should be set to 1 and any others you want checked to 2

For more information see
man fstab
