SQL Server 2005 full backup script

P: n/a
We have a script that I had to rework a little bit for 2005 that does
a full backup for every database on the server... For some reason on
some nights the script does not backup all databases... Its like it
skips over it for some reason... Output of the script below on the
night in question was:

Executed as user: NT AUTHORITY\SYSTEM. master [SQLSTATE 01000]
(Message 0) Status is ONLINE dbname / dbdevice = master / SQLBUmaster
[SQLSTATE 01000] (Message 0) Processed 376 pages for database
'master', file 'master' on file 1. [SQLSTATE 01000] (Message 4035)
Processed 2 pages for database 'master', file 'mastlog' on file 1.
[SQLSTATE 01000] (Message 4035) BACKUP DATABASE successfully
processed 378 pages in 0.169 seconds (18.298 MB/sec). [SQLSTATE 01000]
(Message 3014). The step succeeded.

A normal night on this particular server includes two other databases
like below:

(Message 0) Processed 376 pages for database 'master', file 'master'
on file 1. [SQLSTATE 01000] (Message 4035) Processed 2 pages for
database 'master', file 'mastlog' on file 1. [SQLSTATE 01000] (Message
4035) BACKUP DATABASE successfully processed 378 pages in 0.711
seconds (4.349 MB/sec). [SQLSTATE 01000] (Message 3014) msdb
[SQLSTATE 01000] (Message 0) Status is ONLINE dbname / dbdevice =
msdb / SQLBUmsdb [SQLSTATE 01000] (Message 0) Processed 688 pages for
database 'msdb', file 'MSDBData' on file 1. [SQLSTATE 01000] (Message
4035) Processed 5 pages for database 'msdb', file 'MSDBLog' on file
1. [SQLSTATE 01000] (Message 4035) BACKUP DATABASE successfully
processed 693 pages in 3.743 seconds (1.516 MB/sec). [SQLSTATE 01000]
(Message 3014) SBC [SQLSTATE 01000] (Message 0) Status is ONLINE
dbname / dbdevice = SBC / SQLBUSBC [SQLSTATE 01000] (Message 0)
Processed 11577184 pages for... The step succeeded.

The script is schedule to be run nightly and it looks like this:

Any help I would appreciate it... As you can see from the output above
it looks like its not even getting the database name to backup in the
cursor. But that just doesn't make any sense to me... why could that
be.

I don't see any apparent flaws, but two thoughts:

1) Make the cursor over sys.databases INSENSITIVE. The default cursor
type is dynamic, and it makes me nervous.

2) You should probably have some TRY-CATCH around the backup commands.
If backup fails with an error that aborts the batch you will not
backup the rest of the databases.

Both very good ideas... thats probably why I didn't think of them...
I'll give it a try and let you know.
