One: four backup methods of sql server database

1. Full backup

Full backup only takes one step to complete the backup of all the data, if all backups, it may take a long time, after the backup is completed, there will be a copy in the database.

two。 Differential backup

The main purpose of differential backup is to record that only the changed data is backed up after the last backup. The previous data need not be backed up, and it is smaller than the database backup. Of course, the backup speed is also very fast. Data can be backed up regularly, so as to reduce data loss.

3. Filegroup backup

When the data is relatively large, in general, backup will take a lot of time. We can put the data in the filegroup and set a file to the default. Only individual files can be backed up. There is no need to back up the entire database, thus speeding up the backup speed of users.

4. Log backup

A log backup is a record of all transactions in the backup log, and we can use the transaction log to restore the data to a certain point.

Second: frequently used backup combinations

In general, many people choose to use a combination of full backup and log backup or log backup, a cycle of one week, log backup or log backup from Monday to Saturday, and full backup on Sunday.
