CHKPT={Y | N | nnn}

Default N
Allowable Values Y, N, nnn
Minimum 1
Maximum 360
Alternate Specification CKPT

You can use this parameter to specify whether to take checkpoints during this transfer. Where, nnn specifies the time in minutes that each checkpoint takes. If Y is specified, the interval defaults to five minutes.

Note: Checkpoints are taken at time intervals; therefore, you can start a transfer backup at the point of failure if the transfer is interrupted.
Note: Checkpoint restart processing is not supported when Spanned files are used (RECFM=VS or RECFM=VBS).
