Lost data forget how to process the backup [graphic] 1th 2 page _mssql

Environment Description:
A company installed a SQL Server database, to ensure that the database can be repaired in a timely manner, the administrator does a backup operation, such as full backup + differential or full backup + transaction log backup, and the time of backup is to do a full backup every 6 hours, at 1, 6 points, 12, 18, and within 6 hours, a differential or transaction log backup is made every 1 hours, combined with scheduled tasks.

If there is a scenario where, at around 2:40, suddenly the database is corrupted, a differential backup or a transaction log backup is not automatically done by 3 o'clock, then how do you recover data from 2 to 2? This requires recovery through the backup tail log.

Implementation steps:

1, first create a database, and in the database to create a table Dreamfire do test.

2. Second, create two backup devices (where backup data is stored), a full backup of the data, a differential backup of the data. Do a full backup + differential backup, if full backup at 1 points to do a full backup, 2 points to do differential backup.

Make a full backup first:

After you have completed your full backup, add a piece of data to the table in the database you just created to test.

The database is then backed up by a differential:
