Hi all: This question I am posing caught me off guard and was wondering what the MF world does about Data Base backups. The largest DB I had e been exposed to was around 60 3350 volumes and that was 20+ years ago. The backup of the entire DB took about 3 hours and that was by a special back program written by the vendor.
The webinar that I watched was of course a PC Data base. One of the questions was: Have a file system so large or dense that you haven't completed a full backup in several months, if ever —————————————————— Have any of you had this much data to back up you couldn’t do it … for several months??!!!! I talked with a friend whose company has a large (credit history of all the people in the US (plus a few over seas)) and according to him they back the data up in several ways, but the current back up is to replicate the data and then back it up off the replicated data and he said 3-4 hours. When I told him of the comment that was made in the webinar, he said: “If I couldn’t back up the data in 4 hours tops, he would be fired.” I though this might be an interesting question for the people on here. How long does it take to backup your largest DB ? What are the various methodologies do you use for backup of your largest DB? Finally would you still have your job, if any portion of your DB went for say over 1 day without a proper backup? The 1 day is a variable and I plucked it out of nowhere and was wondering what is your magic number?
