The following example describes how Incremental FlashCopy® can be used to create periodic backups to tapes.

• Step 1 - Copy volume VOL00A->VOL00B by performing initial Incremental FlashCopy from volume VOL00A to VOL00B. Background copy task copies all the tracks on the source volume to the target volume.

  COPY FULL INDYNAM(VOL00A) OUTDYNAM(VOL00B) DUMPCONDITIONING -
       ADMIN PURGE FCINCREMENTAL

• Step 2 - Backup volume VOL00A by performing full volume dump from volume VOL00B to tape.

  DUMP FULL INDYNAM(VOL00B) OUTDD(TAPE01)

• Step 3 - Allow update to volume VOL00A
• Step 4 - Refresh volume VOL00B by performing subsequent Incremental FlashCopy from volume VOL00A to volume VOL00B. Background copy task copies changed tracks from volume VOL00A to VOL00B.

       ADMIN PURGE FCINCREMENTAL

• Step 5 - Repeat steps 2-4.
