If I implement a brand new GFS backup rotation, where M-Th I'm running incremental backups, and on Friday I run a Full backup, how will the first incremental backup that runs on Monday know what to backup? My understanding is that the incremental (or diffs) are to run after the full runs...that is, they backup what has changed since the last full backup.
I've been reading up on the GFS rotation, and every chart I look at, and explanation that I read, has it with the incrementals (or diffs) running during the week, with the full running on Friday or Saturday. This seems backwards to me, in terms of grouping tapes for weekly sets. Shouldn't each set of weekly tapes you keep have the full backup leading, with the incrementals following???
