| It means you would be having a T log backup till 3:15 AM.Take a tail log backup,restore your last Full Backup,then last differential backup if available and all the available tlog backup i.e till 3:15 am and then restore the tail log backup.PBUH |

| Oops sorry I overlooked that you mentioned that Tlog file also crashed.So it would mean that you wont be able to take Tail log backup.So I don't think it would be possible to have a point in time restore.PBUH |

| Hi Schin,Ragu is taking full backup at 12AM and differential backup schedule after 6 hours. So in this case I think he will restore last full backup and then available transactin log backups. |

| so it's not possible to restore a database to specific point in time. My assumption is correct.--Ragu ThangavelJunier Sql Server DBA |

| Yes but restore should be your last resort.You can try to repair the database using DBCC CheckDB REPAIR_REBUILD or if possible use some 3rd party tool to repair the Tlog file.PBUH |
