Setting up SQL Server® Authentication for SQL Server 2012 or later

Starting with SQL Server 2012, security privileges changed and you cannot use the LocalSystem account. Previously, you could use the LocalSystem account as the default for the sysadmin role. For SQL Server 2012 or later, use a domain account — including Administrator — that has the SQL Server sysadmin role or change the Log on as option for SQL Server Service to use a domain user that has the required privileges. If the SQL Server is not part of a domain, you can use a local user that has the sysadmin role or change the Log on as option for SQL Server Service to use a local user that has the required privileges.
1
Ensure that the selected domain or local user account has the sysadmin role assigned to it.
2
Complete one of the following:
•
In Windows Control Panel > Administrative > Services, locate and select NetVault Process Manager, and click Stop. Right-click NetVault Process Manager, and select Properties. On the Log On tab, ensure that NetVault Backup runs using the account that has the SQL Server sysadmin role. Start the NetVault Process Manager.
•
In the SQL Server Configuration Manager, click SQL Server Services. In the details pane, right-click the name of the applicable SQL Server instance, and click Properties. In the SQL Server <instanceName> Properties dialog box, click the Log On tab. For Log on as, select the account that has the SQL Server sysadmin role. In Windows Control Panel > Administrative > Services, stop and start the SQL Server Service.
•
Use SQL Server Management Studio to add the domain or local user account that has the sysadmin privileges to the SQL Server. You can use SQL Server Management Studio to add this account, or enter the following in a command prompt:
CREATE LOGIN [<domainName>\<loginName>] FROM WINDOWS;
GO

Defining a backup strategy

The purpose of creating SQL Server® backups is to recover a database that is damaged from media failure or data corruption. Reliable use of backup for recovery requires a strategy that maximizes data availability and minimizes data loss, while accounting for defined business requirements.
A backup strategy is divided into two pieces: a backup piece and a restore piece.
•
The backup piece defines the type and frequency of backups that are required to meet the goals for availability of the database and for minimizing data loss.
•
The restore piece defines who is responsible for performing restores, and how restores should be performed to recover from the particular type of damage or failure.
 
* 
IMPORTANT: If you use Plug‑in for SQL Server, verify that you are not using a third-party program to complete additional backups of SQL Server. Otherwise, a conflict might occur during the restore or recovery process when the differential backups do not match.

Reviewing the available backup methods

The plug-in offers the following backup methods:
•
Online Virtual Device Interface (VDI)
•
Volume Shadow Copy Service (VSS)
The plug-in supports implementing an Online VDI or a pure VSS backup strategy, not a combination of the two.
