Chapter 5. Creating Backup Archives
This chapter provides general information about backup methods, describes how to
backup Microsoft SQL Server databases, and which options can be set using Acronis
Recovery for MS SQL Server.
5.1 General Information
Backup is crucial to maintaining timely and consistent record of your databases for
recovery in case of failure. Acronis Recovery for MS SQL Server offers an easy and
flexible process for creating of backup archives.
5.1.1 What is a backup?
The concept of backing up data is based on copying it to a safe place to restore when
necessary. With an active database you need to backup and protect more than just
your database files and data. Databases include many components, such as transaction
logs, that must be backed up as well to ensure a fully functioning database upon
restoration.
Acronis Recovery for MS SQL Server is a tool that backs up the necessary tables, data,
and user-defined objects, but treats the database not just as a combination of files.
When the backup procedure starts, Acronis Recovery for MS SQL Server finishes all the
active transactions, makes a snapshot of the database and resumes the transactions
immediately. The database idle state is minimal; and the backup will be written to the
archive location while the database is online.
Using this process to back up the database ensures that the restored copy will
be operational as is. Since the copy is made according to the snapshot, no
transactions made after the start of the process will be included into the
current backup.
Acronis Recovery for MS SQL Server backs up transaction logs separately. See 5.1.2
"Backup Methods" for detailed information.
5.1.2 Backup Methods
Acronis Recovery for MS SQL Server can create full, differential and Transaction Log
backups for comprehensive protection of your data from hardware failure, user errors
or even natural disaster.
