Home -> Community -> Mailing Lists -> Oracle-L -> RE: Backup Strategy
Gene is a sysadmin at heart. He hasn't been fully groomed and trained in the Data Base Arts. I think that's the main reason for his (unjustified) reluctance to TRUST something that works.
It's like physics. You see it every day, the math doesn't make 100% sense to you, but you have to convince yourself that certain facts are true before you can move to the next level. Play with hot backups, test the scenarios, learn to trust it. Convince yourself that it WORKS.
I have a boatload of scripts. Gene you should be able to modify your trusty dusty cold backup scripts to execute the alter tablespace commands dynamically, one by one, and do the copy. should be a minor change. There's one caveat: you can't do this if you aren't in archive log mode.
I'll look through what I've got and send them to you.
(For those of you who don't know, Gene is my old boss. I taught him a lot about Oracle - LOL... My favorite taunt: Gene's afraid of R-Man! Gene's afraid of R-Man!)

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.
