If you don't have a backup, that data's not coming back.

Triggers fire as the data is deleted, in the trigger you can roll back the delete or audit it or whatever else. But it's of no use after the data has been deleted.

Why on earth are there no backups?

.. which are all important... I am not having backup or Trans log ...

It's a petty you need to find this "missing link" the hard way :crying:

You need to define a DRP for every database ( and evaluate that time and again if you add/remove objects !)

In the mean while you'll have so sit on the blisters and repair as good as the info you get/have.

After this do you think a weekly backup is enough?

How to find which user has deleted the data

Unless you had a trace running, there's little chance of finding that out after the fact. Especially if it's quite some time after the fact

What is the Use of
select * from sys.fn_dblog(null,null)

It reads the database's transaction log. It's an undocumented feature, the log's not designed to be easily human readable and since you're in simple recovery (or I assume you are without log backups), the log records get overwritten once they're not needed any longer and when new log records need to be written.

Create another log backup and restore your full backup from last weekly to an alternate dbname, using NORECOVERY, then restore your logbackup to that alternate dbname up to the point in time you assume all rows were still in place.

ps. let's hope your db is using full recovery model

Hi

This is local developement one thats why planned as weekly to reduce the harddisk size

There is no other way to protect the data other than Backup and Log.

In my case there is no Possible to Recover the data

That's the whole reason that you do backups.

In my case there is no Possible to Recover the data

It would appear that way.

Your best bet would be to use a third party log app to try and match your transactions and data.
