Hi,
   from reading this doc: http://www.microsoft.com/technet/prodtechnol/sql/2005/sqlwriter.mspx
my understanding is that the SQL writer service is intended to allow third party apps to utilise VSS. Is this correct? What I need to know is whether or not ntbackup needs the SQLwriterservice to back up SQL 2005.

thanks!

The recommended method for backing up SQL Server DB's will still be to have SQL Server do its own backup (probably to another disk on the same machine), then have NTBackup or other general-purpose backup software back up the resulting .BAK files to an external medium.

As far as I know, NTBackup doesn't do anything with SQLWriter -- but I can't say for sure.

Thanks Daniel. Ok, I understand you're not 100% on whether or not ntbackup uses the sqlserver writer, but we could look at this another way.

The end user is using ntbackup to back up .bak files- that much I'm sure of. If that is the case, would ANY SQL writer (or MSDE writer) be needed to backup the actual .bak file?

thanks

No, I don't think the SQL Writer would be needed in that situation.

SQL Agent does need to be running to schedule those backups to the .BAK files ... I guess it's possible that IT uses SQL Writer ... but if the .BAK's are being generated reliably, I wouldn't look any further.

The .BAK file is just a file -- it's not locked down (except during a backup or restore) for the express purpose of being able to be backed up further.
