Which image comes first, full or incremental?

Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit. Sed posuere consectetur est at lobortis. Vestibulum id ligula porta felis euismod semper. Donec ullamcorper nulla non metus auctor fringilla. Aenean lacinia bibendum nulla sed consectetur. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Cras mattis consectetur purus sit amet fermentum. Morbi leo risus, porta ac consectetur ac, vestibulum at eros. Sed posuere consectetur est at lobortis. Etiam porta sem malesuada magna mollis euismod. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum. Curabitur blandit tempus porttitor. Sed posuere consectetur est at lobortis.

Full would superced incremental... kinda...

If the full image was created LAST, then that would be all you would restore, and in fact, any incremental image at that time would be useless and should be deleated.  If however an incremental image ran last you would first have to restore the full image and then restore the incremental image to be back to normal.  If you rotate your media day to day, then you always have at least one good image to work with. 

 

So you are correct.  Only install the incremental image if it was created last, otherwise you will overwrite the good data (newest) with older data.  The incremental image contains only those datum that changed after the last recorded full backup image.  Make sense?

 

Thanks for the reply.

Yes each day at noon I have a full image run and then an incremental that night. So each full image has a cooresponding incremental image. 

So if I understand you correctly...after restoring the full image, I then would restore the cooresponding incremental for that full image and it would only add new information to the restored drive that happened after the full restore and not just completely overwrite the full restore image.

Yes.

 

Well it MAY, depending on how much stuff changed.  This usually isn't the case though.  Incremental images are smaller than full images , normally.

Good luck.

Thanks for the good info.

I just wanted to make sure that I was restoring the full and incremental image in the proper order.
