Use checkpoint table to keep the replicat checkpoints. However, do not use a checkpoint table when configuring Replicat to operate in integrated mode against an Oracle target database. It is not required in that mode.
If Oracle GoldenGate 12.1.2.1.8+ is used, then you can also use the Automated Remote Trail File Recovery by Pump feature [2]. You can just restart the pump process to enable the automatics trail file resending. With this, you don't need to backup the trail files.
