-124: Checkpoint for SAVA DATA is missing 

Explanation:

This error only occurs in the OMS environment.

You have forgotten to create a checkpoint using FORCE CHECKPOINT that can then be used for a SAVE DATA command.

Unlike OLTP operation, where the data migration always creates a checkpoint itself, in liveCache, data migration is separate from the creation of checkpoints.

User Action:

Create a checkpoint using FORCE CHECKPOINT and restart the backup.
