Can that give performance issues? We have been troubleshooting severe performance problems all day, on a busy web application that uses SQL server 2008 R2. The database is 120 GB. In order to try to reproduce the problem in the test / dev environment we took a full backup of the database using Management studio.

The strange thing is ... after we did the backup ... the performance issues are gone!

We have since figured out that no full backup has been run for over 1 month and no maintenance jobs are scheduled on the SQL server The recovery mode is set to Simple

My question is: I you don't ever perform a full backup. Can that give performance issues? I am thinking about that the transaction log is never commited.

or is this just pure coincidence?

What did you run to do the backup? It's possible that the transaction logs were truncated at that point, as you no longer needed them to roll back - you have the backup for that.

Can that give performance issues? We just fired up management studio and right clicked the database and created a full backup.

that may well be what happened.

you may also want to setup some maint. plans to re-build indexes and some other stuff...

like a nightly backup ....

Can that give performance issues? ohh yes. We are going the hold a DBA tomorrow and have him to go through the server. The client thought it was good enough just to snapshot the virtual server once a day.

Can that give performance issues? Might depend on the config of your backup. A typical "backup" can consist of a number of processes, including compressing, truncating, re-indexing, etc.

Can that give performance issues? @fabian: A backup forces a write to committed data and also does a truncate of unused space, so maybe your disks are full?

Maybe it's the OS which is having a hard time due to low disk space.

Can that give performance issues? SSMS -> Right click database -> Properties -> Options -> Recovery Model. Yours is probably set to Full.
