Database Recovery Models

SQL Server supports several database recovery models to control transaction log maintenance. You set a

specific model to each database. The VCM database settings are set to Simple by default.Retain these

settings for all VMware databases, and use the nightly full or incremental backups.

Simple Recovery: The VCM database settings are set to Simple by default. The transaction log retains

enough information to recover the database to a known good state when the server restarts.

Transaction log backups are not allowed and point-in-time recovery is not available. Simple recovery

causes the transaction log file to grow. SQL Server is in Auto Truncate mode, so the log file periodically

rolls over as data moves from the log file to the data file.

Bulk Logged Recovery: The transaction log retains all normal transaction information and discards

transactions that result from a bulk operation. VCM uses the IROWSETFASTLOAD interface extensively,

which is bulk logged.

Full Recovery: The transaction log retains all information until it is purged through the SQL Server

LOG backup operation, which the database administrator uses to perform point-in-time recovery. Full

recovery allows incremental backups of the database. Do not use point-in-time recovery because

certain factors in VCM weaken the point-in-time recovery model. If you implement Full Recovery, you

must set up scheduled daily backups of the transaction log. The log files will continue to grow and

accumulate changes until you back them up. A Full Recovery database that does not have scheduled

backups can fill its disk and stop the system.

Configure Database File Growth

Configure the autogrowth properties of the VCM database and log file to restrict the file growth from

affecting VCM performance.

The VCM installer creates a 2GB data file and a 1GB log file. These files grow as ongoing operations add

data to VCM.

The file growth for each file is set to the default value for Microsoft SQL Server 2008 R2. In some

environments, these default values can result in file fragmentation or reduced performance. The following

procedure sets the autogrowth property in each database.

Understand the database recovery models. See "Database Recovery Models" on page 67.
