Home -> Community -> Mailing Lists -> Oracle-L -> RE: Backup Strategy
Henry brings up a good point. Users accept scheduled downtime (cold backups), therefore it allows me perform system maintenance w/out asking for permission :) They always want 24x7 and never give permission.
>>> Henry.Poras_at_ctp.com 10/04/01 05:55PM >>> And what about changes to the init.ora? No scheduled downtime is necessary with cold backups. (of course more stuff can be changed on line these days)

Well for 1 reason, Cold backups are restored using OS cmds, no need for Oracle recovery, whereas, Hot Backups require OS cmds + Oracle recovery. One exception is pt in time recoveries. I do have 1 db that will be web-enabled, therefore 24x7. So guess what I have to do, Hot Backups. I am not against them, just prefer cold. Anyone have hot backup scripts? Lisa, you are the script ninja, got 1 of those scripts lying aorund. Thanks :)

There are a lot of sites out there that cannot afford to have the database come down even for 5 minutes so you might want to spend some time getting the warm fuzzies over hot backups. I swear, they work.

I personally prefer cold backups over hot. Always better when the files are closed. But hey, this is coming from someone who still doesn't trust Rman :)

>>> kimberly.smith_at_gmd.fujitsu.com 10/04/01 12:40PM >>> I agree with your export statement but I must question this one. I cannot think of a single reason to get a cold backup over a hot backup. I can think of reasons for cold backups but if I was doing hot backups already I would not shutdown my database just to get a cold. There is a myth out there that hot backups are not as reliable as cold backups and its false. Your really not saving anything time wise if there is a crash (unless of course all your disks crash as you are bring up the database).
Weekly cold backups are a good plan.
