Live backups

A live backup is a continuous backup of the database that helps protect against total computer failure. You can use the redundant copy of the transaction log to restart your system on a secondary computer.

If your system fails, the backed up transaction log can be used for a rapid restart of the system. However, depending on the load that the database server is processing, the live backup may lag behind and may not contain all committed transactions.

You should normally run the dbbackup utility from the secondary computer. If the primary computer becomes unusable, you can restart your database using the secondary computer. The database file and the transaction log hold the information needed to restart the database.

An alternative to a live backup is to use database mirroring. See Differences between live backups and transaction log mirrors.
