You can use a combination of FlashCopy® image copies and sequential image copies to define an efficient backup procedure that uses minimal disk space.
Procedure
To back up data efficiently:
-
Create a consistent FlashCopy image copy virtually instantaneously by using the COPY utility with the FLASHCOPY CONSISTENT option.
Alternatively, you can use the LOAD, REBUILD INDEX or REORG utility to create an inline FlashCopy image copy.
-
Create a sequential image copy from the FlashCopy image copy by using the COPYTOCOPY utility.
-
To free up disk space, delete the FlashCopy image copy by using the MODIFY RECOVERY utility with the FLASHCOPY ONLY option and the DELETEDS option.
The DELETEDS option deletes the data set. Otherwise, only the SYSCOPY records are
deleted.
If you later need to recover the object, the RECOVER utility knows to use the sequential
image copy that you created in step 2 as a possible recovery base.
