If you have circular logging disabled then you should be able to restore from your last backup and all the log files will replay. This will then bring the databases back to the point of failure.
Just be sure that you restore the MS Exchange Information Store.

As the first guy said, if you have not enabled circular logging there is a fair chance the logs will replay and you will get all your mail from the last two days.

Prior to doing that it is worth just checking with eseutil and isinteg that there is indeed no data in the stm files. Worst case scenario at least you get your stores up to a point where you can mount them and see the damage inside.

eseutil do not let me repair the database it says it is not up to date and some other errors.

How should I make the restore? should I copy the priv1.edb and priv1.stm to the MDBDATA folder replacing all files or I restore the whole folder and then replace the log files with the actual ones.

Restore the edb and stm files and copy them into MDBdata.

Glad you resolved the issue.
BUT...
You stated that you were unable to recover the backup. It should now be a priority to resolve that issue. What good are backups if you can't restore them properly. Do this now before you have to do another restore.

Just my 2 cents worth.

I tried all kind of programs (veritas, arc serve...) and I am not able to do a properly backup, it seems when I have to restore data everything goes wrong. What software do you think ist the best to do the exchange backup.

I have used Veritas and Windows Backup without any problems. Veritas has more features than Windows Backup but you have to purchase an Exchange Agent from Veritas to backup Exchange databases while they are online.
