I agree. I was thinking about an incident I heard about where a database server that made many thousands of transactions per day had to be restored from backup. The recovery process was slower than the everyday transactions so it was never going to actually catch up to real time.You mean backups in general? That would be an interesting topic, but the more important topic is, of course, recovery. A backup system is (almost) useless if it takes you three days to recover your data.
I'll take issue with the wording here - it's only (almost) useless if it takes three days and you simply must have it the same day. Otherwise give me three days recovery time over no recovery, and I will call it anything but useless.
Recovery is of course the important thing, but recovery is moot without backups.
Basically it would take 3 days to play back one day of logs. In a situation like that you can pretty well scrap yesterday 'cause it will cost you today and tomorrow.
