I've been corrected, this is how it works:
=20
So essentially this would be what we want, by using
differential-incrementals in between cumulatives we will save tapes. By
using cumulative's we don't have to worry about restoring 1-90 backups.
The benefit of this is we only have to restore the last cumulative as it
marks all of the changes from the last full.
=20
So in my example below, we'd restore like as someone on the auburn ML
said, the full, cumulative and 29+30+31 incremental.
