Hi I am trying to figure out my best bet backup strategy. I know in an ideal world its best to just go with full backups every night but what if space it tight. So im also looking at differential and incremental as well. Although its hard to tell really what data will change on a daily basis my question is what would the diff and incremental space requirements look like if the fist complete backup was say 10GB to keep it simple then then next night 5GB of data had changed the night after that 30GB had changed and so. if there a model i could follow to see what size and how many tapes i might end up needing.
