Few months back, I installed a sql server 2005 on one of my client machine. I gave him a backup option to take backup timely but he never took any backup.
Today he called me that "i m not able to see any record of mine." I visited at my clients system and saw that none of the record was present on the tables. There was not even a single row in any of the tables. Then I checked if he has any backup file which i found to be absent.
I asked him the reason what could be the possible cause. He said it might be due to virus.
After this I checked the size of mdf and ldf file and found it should be what it is. when i created his server mdf ldf file had 2MB of database now it is 83 MB and 193Mb mdf/ldf respectively.
This shows the data is still present in it but it is not being displayed.
What could be the possible cause and how can i restore all data back to my tables ?
