Not using any version of it now.

Veritas Net Backup and RMAN.

When BMC purchased DataTools, the support for SQL*Backtrack really went down the tubes. I don't know if it's improved or not, but I don't really miss it now.

You must be using an old version. Been there done that. Works!

Unless:

You do a point in time recovery, find out you were given the wrong time, and try to do it again.

Not so simple, can't be done from the SQL*Bactrack menu.

SQL Backtrack and Netbackup! No manual tracking. Restores couldn't be simpler.

Richard,

    Distateful is being nice. Try down right horrifying is a more appriopriate
description. Been There, Done that, now have three Unix SA's who handle it.

Life is so grand!!

Yes I personally run Veritas Netbackup for both cold and RMAN. A fiber SAN has its added benefits as well =). I have never really explored the implications of these other utilities. My head filled with many distasteful visuals. Yes, I agree with you and I realize that I am spoiled <knocking on wood>.

I've used cpio, dd, and fbackup to do hot and cold backups before, but never
again. With those utilities the burden of keeping track of what is on which
tape rests with you and normally a stubby pencil & pad of paper because you
know
what won't be available when you need to do a recovery. They do work be assured, but the administrative overhead is just not worth it anymore, even
for
a small shop. Get a copy of Veritas or OmniBack or some other software package
that does library management for you and preferably integrates with RMAN. Life
can be so much easier!!

It would be interesting to see how you would explain how either cp or dd (which know nothing of archive log mode, or the concept of hot backup, itself, none the less) is going to keep things consistent, when these utilities themselves are for point in time operations.

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. Ron

>>> Robyn_at_iTeamTech.com 10/02/02 08:08PM >>> 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.
