Ruth, Tom, or anyone


   So what is the final checklist before you take a deep breath and stop
cold backups. I have successfully run a disaster recovery test, but after so
many years of the comfort of a cold to go back to, it sorta takes you back.

I haven't done nor recommended a cold backup in 3 years since I've been
using Rman.  Just not needed anymore.

I still prefer cold backups when performing full OS backups.

Lest we not forget the archivelogs also during this backup procedure.

I forgot about alter tablespace begin backup; etc. I am spoiled, I use
rman


to do online backups.  No problem with recovery!

This doesn't sound right.  Put the database in hot backup mode,
backup (whether using cp to a staging point like the poster here
is doing or straight to tape using dd or dump or some other utility),
come out of hot backup mode.  Why wouldn't you be able to recover?

If you want to be able to use any OS backup for restore/recovery that
database must be closed when you do the backup.  If it is not, you
won't be


able to recover.



Just a thot,


Ruth






Robyn,


 We used the DD method on pre 7.1 oracle with RAW devices. It worked
fine except that it  used a lot of tape dumping a raw device when only
a


small portion was used. Using a dd command to place a copy of the data
on tape should not be a problem if a restoral is needed. The dd
function


is just another OS method of copying data to a tape. I don't know for
sure but I think there might be some issues about transportability of
the dd tape.


Other users will know about the transportability issues.

Hello,



I need some info about backups.  I am working on a customer site, and
have implemented both exports and hot backups.  Both jobs copy to a
separate mount point, and a job scripted by another individual then
moves the files to tape.



Here's the problem - he's using a dd command, primarily because it
provides a succinct output he can email to non-technicals.  The file
system is built on a 12 disk A1000 array.  We've provided him with a
ufsdump script, but he's doesn't want to use it. Can the system be
recovered from this tape?  Has anyone ever relied on a dd for a daily
backup method? The system is Oracle 9i on Solaris 8.
