Find out how or why Excel file has disappeared from server folder

Don't have much hope for this. iSCSI attached storage repo on Server 2008 R2 box.

My user sent me his Excel Recent docs listing which shows he saved file 2014Forcast V8 to mapped drive X:\accounting\2014 on Friday the 3rd. This morning he launched Excel and clicked the link and the file was not found. I verified the file is not on the server. I checked my backups which ran on Saturday the 4th and only ht e2014Forcast V7 file was included in the backup.

 I did a search of the server folders near this to see if it got accidentally dragged into another location. I did a search on his system for temp files that might have gotten left over to recover the file. He is OK with recreating it but is raising some concern that File disappeared from server.

I can't think of anything to do other than unmount the entire iScsi drive and run FDISK on it.  Is there some specific logfile that I can check to see if there was a write error for this file?  

Can anyone think of a plausable explanation for what happened here? I've advised the user to save locally and then copy the file up to the server after the local save for now.

I did check the trash under both my domain account and the Domain Administrators account. Even checked the trash on the local users computer

Do you have mirrored drives or some sort of SAN arrangement that could cause a drive swap?

Besides backup, any IT division should have a disaster recovery plan. You will find a few tips below relating to the development of such a plan and to what issues one should pay special attention in the course of backup planning.

No. Drobo (ugh don't ask) iSCSI attached volume. Drobo does have proprietary raid setup but I have no notice of a file straight up disappearing before.

It will depend what level Raid that drobo is set up around.  If it is a straight raid 1(mirror) setup then it is possible that the file will disappear.

You should be able to see from the drobo interface if there is an issue with bad sectors on a drive that could be causing the problem.

Running an fdisk may identify any issues, but drobo should have some integrity check tools of it's own to use.

I apologize for my delay in getting back to this question. I finally had a chance to run the Drobo Utilities and found no issues with the RAID array. I have had no further issues or reports of a missing file. Unless someone has another suggestion on where to look for possible indicators of further issues I'm inclined to close this question and give the points to Sweetfa2 for his/her participation.
