Why has the retention period for backed up data been decreasing?
I was discussing something with a sysadmin last week, and he made a comment that backed up data is often only retained for a few days now. It wasn't long ago that the standard I was familiar with was a 30 day retention of data. I didn't get around to asking why the retention period had decreased so much before we parted ways. Was he right? Is backup data only being kept for a few days, and if so, why has there been such a big decrease in the retention period?
