Need help backing up database

Question:

  AIX 3.2.5

  Customer needs to know if the method of backing up their
  database given to them by their database support people is 
  a good way to back up their data.  Their database does skip 
  over the Logical Volume Control Block (LVCB) on the raw LV
  they are using to store their data.

  Database Support Proposed Method:
  --------------------------------
  backup:
  dd if=\ of=\ bs=\
  
  restore:
  dd if=\ of=\ bs=4096 seek=1

  The above method should work, but here is another method we
  would suggest.  Notice that the below method includes the 
  conv=sync parameter in order to pad every block to the input 
  block size:

  backup:
  If you are using a tape drive set it to 0 bs or 4096 bs.

  dd if=\ of=\ conv=sync bs=4096

  restore:
  If you are using a tape drive set it to 0 bs or 4096 bs.

  dd if=\ of=\ conv=sync bs=4096 seek=1
