Data Backup and recovery of articles, journals and books can help you traverse your way through the process of data backup and recovery of any missing data. In this backup and recovery resource guide, you would learn more about the most important data backup topics available on this website.

Data is fundamentally regarded as one of the most important asset of a company, just like people. Another important issue relating to backup of data is the ability to recover lost data and keep your business up and running.

One of the key responsibilities of a database administrator (DBA) is to prepare for the possibility of media, hardware and software failure as well as to recover databases during a disaster. Should any of these failures occur, the major objective is to ensure that the database is available to users (as a back up data), while ensuring that there is no loss of data. DBAs should evaluate their preparedness to respond effectively to such situations by answering the following questions:

  • How confident is the DBA that the data on which the company business depends are backed up successfully and that the data can be recovered from these backups within the permissible time limits, per a service level agreement (SLA) or recovery time objective, as specified in the organization’s disaster recovery plan?
  • Has the DBA taken measures to draft and test the procedures to protect as well as recover the databases from numerous types of failures?

The following is a checklist for database backup and recovery procedures that are explained throughout this article:

  1. Develop a comprehensive backup plan.
  2. Perform effective backup management.
  3. Perform periodic databases restore testing.
  4. Have backup and recovery service level agreement (SLAs) drafted and communicated to all.
  5. Have the disaster recovery plan (DRP) database portion drafted and documented.
  6. Keep your knowledge and know-how on database and OS backup and recovery tools up to date.

Without knowing and understanding the basics, it would be difficult to kick-start data backups. Here are a few things you should know before initiating data backups:

  1. Sometimes, database administrator (DBA) confuse data backup with data archiving. The two have a separate functions and as such should be treated separately.
  2. Most commonly, backup have different types like a full backup, incremental backup and differential backup. Other backup types include synthetic full backups, mirroring, reverse incremental and continuous data protection.
  3. Online data backup is becoming a popular alternative to tape-based backup. In this expert response, learn if online backup services are ready for enterprises.
  4. Data backup is just as important to small businesses as it is to larger enterprises.
