proper and safe way to copy ldf and mdf files.

sql server is the rdbms

is it safe for me to stop the sql service and then copy the mdf files or ldf files.
or do i have to detach or brind the db's offline to make this a safe process.

i need to copy the mdf and ldf files on a instance but i can't use the backup service for this.
it needs to be a copy and paste job.

also, dumb question but thought i would check my bases.
making a copy of the mdf and ldf files is just as good as making a full copy only backup of a database correct.

thanks a bunch

Yes but stopping SQL Service would make any database in that instance to be unavailable. Also could stop any running process and so with impact in any application.

or do i have to detach or brind the db's offline to make this a safe process.
Safe just because it's only makes a single database offline. Be careful with what I said above about the running processes. The same applies here for the processes relative to the database.

i need to copy the mdf and ldf files on a instance but i can't use the backup service for this.
Why not?

because the sql agent won't start and the server seems jacked up.  Wanted to make some copies of the databases before I dug into the problem.  windows event log won't start either

You can run a backup from SSMS. Just create a new query and run the following command:
BACKUP DATABASE DatabaseName TO DISK='<Path\Filename.bak>'

Open in new window

sweet
so the backup utility within sql server does not necessarily rely on sql agent being started?

There's no backup utility in SQL Server, only the backup command.
SQL Server Agent is only a schedule task for SQL Server. What it does for backups is run the same backup command in a configured schedule.

Try the following command for backing up all databases (I didn't test it):
exec Sp_MSForEachDB 'BACKUP DATABASE ? TO DISK='C:\temp\?.bak''

Open in new window
