Disaster Recovery: SQL Server 2000 on Win 2000 Server.

This past Monday, our Raid 5 array failed on our SQL 2000 server (standard edition). Long story short, we were able to get the data back, mostly. In SQL server Ent. Mgr., I had to restore 4 databases that were 'Suspect' and "greyed out". No problems there... I was able to restore them.

What was interesting was that the SQL Server Agent would not start. As it turned out, a few files were either corrupt or missing after we got the machine back up. We had to restore a few files from tape backup and now the SQL Server Agent starts... but now I have a new problem.

For some reason, my default SQL Server Agent "Job" that is scheduled to run once per day fails. It appears that all of the databases get backed up, but for some reason, the msdbdata.mdf database is NOT being backed up.

I have a few questions. Could my msdbdata.mdf be corrupt? I have a successful backup of the msdbdata.mdf table from 9/10/2007. Can I just restore from that? Will there be any repercussions to any of the other database tables if I do?

Furthermore, should I just restore the msdbdata.mdf, master.mdf and the model.mdf? I really have no idea what these tables do and the repercussions of modifying them. I am not a DBA (obviously) and I just don't want to make an mistakes.

Thanks, CFDev.
Can you pls provide the details of the job history if any ? I guess you mean to say that msdb database backup fails if i interpret it correctly and Yes you can go ahead and restore the msdb.bak dated 9/10/2007 and check........the only issue is that all the jobs,dts packages created since 9/10 will not be available if you restore it.........I don't think its needed its enough if you restore msdb no need to restore master or model dbs..........
|||The "Job" is part of the databases default "maintenance plan". It consists of four parts:
1. DB backup
2. Integrity checks
3. Optimizations
4. Transaction Log Backup

This should be familiar to you, no? Anyway, would be okay to restore the msdb database then? How about the model and master databases? No tables, stored procedures, dts packages or anything has been changed. I just want peace of mind that if I were to restore any of these database tables, it would not effect any of my website's database tables. Make sense?

Yes i am familiar with it if you feel there is no change done in msdb after 9/10 you can go ahead and restore msdb. Master stores all the login information and model acts as
template for other dbs so just restore msdb as it contains all the jobs and dts packages....I dont think restoring msdb would affect your db tables.......

It would also be a good idea to run checkdb on all databases to make sure that they're clean.

You haven't made changes since 9/10, but you'd really rather not trip across hidden problems later.
