What is circular logging?

June 20th, 2009

Circular logging automatically deletes the transaction log files. You can configure the transaction log files to recycle itself, so that the accumulation of data on the transaction log files can be prevented. After enabling circular logging, creation of the new log files is stopped and the data committed to the transaction log files overwrite the oldest log files and save the disk space.

The disadvantages of enabling circular logging are:

You cannot recreate a database at the time of recovery because the transaction log files do not have complete set of data, which helps in recreating the database.

Incremental and differential backup is also not possible, if circular logging is enabled.

What is SSL?

June 16th, 2009

Secure Sockets Layer (SSL) is a protocol used to transmit private documents via the Internet. SSL uses a combination of public key and symmetric encryption to provide communication privacy, authentication, and message integrity. Using the SSL protocol, clients and servers can communicate in a way that prevents eavesdropping and tampering of data on the Internet. Many Web sites use the SSL protocol to obtain confidential user information, such as credit card numbers. By convention, URLs that require an SSL connection start with https: instead of http:. By default, SSL uses port 443 for secured communication.

What is the Backup utility?

May 6th, 2005

Backup is a graphical program used to back up and restore user data. In the event of data deletion or hard disk failure, the backup copy can be used to restore lost or damaged data.

The Backup utility supports three modes of backup:

Full backup backs up all selected files for backup and takes maximum space and time. It needs only one tape to restore data.

Incremental backup provides a backup of files that have changed, or are new, since the last incremental or full backup. It needs the last full backup tape and all intermediate tapes used for incremental backup to restore data.

A differential backup strategy takes minimum space on the hard disk or network drive. The differential backup backs up only those files that have been created or changed since the last full backup. It takes only the last full backup tape and the last differential backup tape to restore data.
