In case of normal OS level backups Full backup is required to go with a cumulative backup. But in case of NDMP even if Full backup has expired, we can still restore data from a cumulative backup if data is in the cumulative backup image.

However unless most of your files change on a daily basis you’re not likely to have most of the files in the incremental. That is to say that a full OR an incremental CAN be restored without respect to the other backups but the INTENT is that the full be restored first then the subsequent incrementals (or a single cumulativeincremental) since that full should be restored on top of it to get the changes since the full. If the full expired but the media it was written on has not been reused you can re-import the full and then restore it. The re-import will change the expiration date relative to the date of import rather than the date of backup.

What happens to an incremental backup whose dependent full has expired. For example A full backup is run and expires in 90 days. 89 Days later an cumulative incremental is run and expires in 30 days. Two days later the Full expires. Is the incremental still useful? If so, to what extent.
