Exchange log files deleted

[anything I don't mind]

One of the 2nd line guys at one of the sites i work at has gone and deleted exchange log files from the last two days thinking they were non essential log files.

What are the options?

Exchange is still up and running and generating new log files. From what i understand the backup will fail until we recreate the log files.

I think we will try and enable circular logging and see if that resolves it.


Will this invalidate all previous exchange backups and make them non usable?

I tried using a file recovery tool but some of the log files had already been over written and i don't want to reinsert corrupted log files back in to the folder. But the log files that were recovered have the incorrect file name anyway so i can't use them. We are going to see if we can recover exchange log files using our netapp snapmirror but other than that it looks like the only option is to recreate the log files?

anyone have any advice?

Ok from what i have read is that exchange logs are deleted the backup will fail because it won't have the correct log files.

I will do nothing and run a full backup tonight and see if it works or not. If it does not work then i will look at solving the issue. We only ever do a full backup of exchange, mon-fri.

Thanks for the advice.

The backups went through ok, we ran the command to check which log files had been committed, the guy got in trouble for it. It was not actually me who would have fixed it, but I was trying to find a solution as well.
