Length of Recovery Time

To decrease the time needed to recover a database, you can implement the following strategies:

Try to reduce the size of the database before backing it up by using commands to reorganize indexes or reclaim unused index space.
Back up the database more often. More frequent database backups result in smaller transaction log files that take less time to roll forward through.
Keep archived transaction log files available on disk. If you keep transaction log files on disk, you will only need to recover the database’s checkpoint but not its log files.
Have a standby system that is ready, or nearly ready, to take over from your online system. For example, you can regularly recover the latest database and transaction log files to the standby system so that the standby system can quickly replace the online system if it fails.
