Re: [Veritas-bu] Incremental backup question
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.

Re: [Veritas-bu] Incremental backup question
Huh? if data is in the cumulative backup image sounds exactly like what I said - you can restore any data in the incremental (including a cumulativeincremental) whether it is NDMP or not.My point was you can NOT restore data from the full that preceded it after that full has expired (without doing a reimport). The fact that you posted makes it sound like you're implying that with NDMP one can restore data from the full even if it has expired so long as the subsequent cumulative is still there. Is that the case? Have you tested this? If so are you saying one can do the restore using normal NetBackup restore methods or are you saying that the image hasn't actually been deleted from NDMP so you can reimport it? If the latter then that is the same as you can do from tape so long as you haven't reused the tape since its images expired.

Re: [Veritas-bu] Incremental backup question
I’m not sure I understand exactly your question, Patrick, but you can’t restore from any image that has already expired. It doesn’t matter what type it is. I know you know that, but being an NDMP backup doesn’t change the way NBU handles an image and expiration.
