This is a really odd one. We have backup exec 2010 and we run 3 backup jobs to disk. then 3 backup jobs to tape. All jobs use relevant agents for SQL, sharepoint and hyper-v. The main SQL backup job runs every evening at 20.00hrs and at 03:00hrs the SQL to tape backup runs. A contractor deleted some SQL data by accident. I have located the tuesday tape and verified the data on it and the date is 22/02/2011 which is correct. I restored to a different location andwithin backup exec it gives me the date of 28/02/2011. If I look within windows explorer it still says 22/02/2011. I have created a new backup to disk folder and recovered data tot his location and as soon as I inventorise it comes up with the date of 28/02/2011. We overwrite media on backup jobs to keep disk space down so we can write to tape more quickly. My theory behind it was if we needed the data we can recover from tape, as we have the data on the tape??
Any help appreciated
