We have a large number of servers which run incrementals every weeknight and then a synthetic full at the weekend. Our understanding was that at the time the synthetic full runs, it should stitch together the data captured in the incrementals, plus any new data or modified data which had appeared *since the last incremental* -- essentially, running another incremental and consolidating it with the previous ones to make a full.
But we've run into a problem where it looked like the synthetic full was consolidating previously run incrmentals, but not capturing anything that was new since the last incremental was run.
IS that normal? Do synthetic fulls not backup data new since the last incremental?
Found the documentation confusing, and I need to check my understanding here.
