Not at all. In fact I thought I was replying to Steve's
post earlier today. Must have pressed the REPLY to the wrong Email
:-)
Just sometimes these threads get too big and it was
probably overlooked. dont worry about it ok ?? I think the point I was making
that the guy that got shot (fired) was SHOT (fired) for all the wrong
reasons!! Even when he tried to advise them (the company) of this status 1
SQL problem.
So yes, I agree with everything you said, including the DB
related stuff :)
Simon
P.S. not everyones posts come in at the same time
(sometimes there are delays of 4 hours or so). But chill ok :) My comments too
were based on Status 1, and from a quote that Steve stated in an
earlier post saying "I think it all depends
upon what you want to achieve. I personally don’t have a problem with
seeing status code 1’s and ignoring them, but some people don’t like to see them
which is why I suggested the exclude lists."
Simon,
Are you deliberately
trying to misunderstand what I am saying? I stated in a previous post that
databases are a special case when it comes to a status 1. There are ways
to backup SQL databases without having to get the NBU agent.
I also stated in a
previous post that you should investigate a status 1 the first time you back up
a client and go over the results with the application owner. You can use
that information to set up exclude lists and show the application & system
owner how this is done and let them manage it. Once you have done that,
you have done your due diligence and it’s time to move
on.
The best thing that any
backup team can do is to put in place a clear charter of their service offerings
and include a delineation of responsibilities. The backup team cannot be
held responsible for the system administrators forgetting to ask to have a new
system added to backups. The backup team cannot be held responsible for
backing up a database that they don’t have knowledge
of.
Again, databases are a
special case in the backup world. My position is that when you get a
request to backup a database server you work with the DBA’s and get their backup
requirements and then schedule a restore test. It is the responsibility of
the DBA’s to ensure that their databases are getting backed correctly up AND
that they can be restored correctly. But, they have to work with the
backup team to get it done. The backup team should NOT have to work in a
vacuum and guess as to what the client wants.
We required that when
someone wanted to add a new system or database to the backups, that a request
get submitted. We did not add new systems or databases unless we got that
request. Everyone knew this and they had no recourse if it turned out
their system crashed and they had forgotten to have it added to backups.
The responsibility was placed firmly where it belonged….on the system
owner.
Finally, the backup
team should provide reports to their customers (managers, system owners,
application owners, DBA’s) using something like Bocada to provide daily backup
status. If you provide them with that information (including systems that
get status code 1), they will be able to review and determine on an on-going
basis if they have a problem or not.
This is all basic
stuff, if you don’t have this in place, then you are asking for trouble. I
was basing my comments on status 1’s on the above being in
place….YMMV.
-stuart 1. People
think that you're working on a backup system. You're not - you're
working on a *recovery* system. If you can't recover, backups are
useless.
2. File system backups are not a replacement for bare
metal restore. It is usually not acceptable to just do a fresh install,
restore files, and expect to be back to where they're started
3.
Error messages really are important. Check them every day or you'll
eventually discover that failures were missed in the noise and backups haven't
run in a long time. When you do a restore is not the time to check to see
if backups actually ran.
4. Audits are important. The larger
the environment, the more likely it is that file systems are missed. This
is especially true of clusters. Sometimes it's not the failures that get
you but the lack of attempts.
5. Backing up clusters by physical
host names will cause you grief.
6. Application owners are responsible for ensuring
the application is recoverable. A backup admin, working in a vacuum, can
not help you.
7. Test your restores
regularly.
There are lots more but this is a start...
