Logic behind setting overwrite
Another question is, I have a hard a time following the logic behind setting the overwrite period. A collage of mine said that you should set your daily incremental backups to overwrite in 5 days and then set your weekly full backups to overwrite in 30 days. This will enable you to keep 30 days of backups. I think this is incorrect, shouldn't you incremental be set to overwrite in 30 days also? For example, If you have a file that changed once on monday, then again on thursday, a weekly backup runs on friday, if on tuesday of the following week you decide you need the data from monday you won't be able to restore it because monday's media is already over written. Correct?
