After taking a differential backup, as it is taken after the last full backup all of the old differential backups become obsolete. A differential backup is used alongside with the last full database backup. Differential backups contain data that has changed since the last full backup was performed and transactions that occur during the backup process.Full database backups allow performing a complete restoration to a state before the backup is performed. Full database backups include all database objects, system tables, data, and transactions that occur during the backup.This article will describe 3 different solutions/approaches for creating a scheduled backup in SQL ServerĪs a part of a backup strategy, several types of backup can be used together.

If you are using differential backups, apply the last differential backup prior to the point in time.ģ. Apply the last full backup prior to the point in time.Ģ. The way to get a database restore of a transaction log is to do the following:ġ. In order to restore a database to a point in time, transaction logs are usually your best option, but the do require more work. Transaction log backups contain a backup of all of the changes since the last transaction log backup.

Differentialĭifferential backups are a copy of all the changes to the database since the last full backup. To restore the entire database all you need is just the full backup. Types of SQL Server Backups Fullįull backups in SQL Server take a complete picture of the entire database. You can use the backup report to determine the frequency of full backups, incremental backups and log backups.
The backups report can be used to help plan system growth and database backup sizes. If you are using the Database Health reports to defragment some large indexes, you would expect that when those were defragmented that the next full backup would be smaller, and that the log and/or differential backups would be larger based on the amount of change associated with defragmenting the index. The backups page allows you to select from the dropdown “Full”, “Differential”, or “Log” to see how your backups are trending over time.
