2AM. We sleeping well. And our mobile ringing and ringing. Message: DISASTER! In this session (on slides) we are NOT talk about potential disaster (such BCM); we talk about: What happened NOW? Which tasks should have been finished BEFORE. Is virtual or physical SQL matter? We talk about systems, databases, peoples, encryption, passwords, certificates and users. In this session (on few demos) I'll show which part of our SQL Server Environment are critical and how to be prepared to disaster. In some documents I'll show You how to be BEST prepared.

  7. 7. A DISASTER – WHAT IS IT
  8. 8. BEST PRACTICE FOR SURVIVING DISASTER ITS ONLY ONE: BE PREPARED
  9. 9. BEST PRACTICE FOR SURVIVING DISASTER ITS ONLY ONE: BE PREPARED Backups  about type of backup ( simple rm / full rm)  about place for stored backup data  about backup window  about procedure used for backup  about backup tools  about backup of „backup logs”  about estimated time for executing backup  about REAL TIME of executing backup
  10. 10. BACKUP > extract from SOP* In the request, backup, should include the following information: • Information about the operating system and application version for online backup and installed updates for these components • a file backup policy, in particular: a number of versions of a file stored the storage time of the next version of the file the frequency of execution of such incremental backups with the proposal of their implementation • Online Backup Policy the storage time of a full backup with storage time such an incremental backup the time of transaction log files the frequency of execution of a full backup with the proposal deadline for its implementation the frequency of execution of the transaction log backup • Information about trees directories / files that should be omitted or included during backup tasks (include / exclude list) • Number and type / model of physical processors, • Does the node will use the connection to the SAN to implement backup
  11. 11. BACKUP (registry) > extract from SOP* This register contains information about a backup plan implemented.  Backup file space:  number of versions of a file stored in a backup  number of days that are kept more versions of a file  number of versions of a file stored in the backup system after its removal from client device  number of days that will store the latest version of the deleted file from the client device  number of days that will be stored in the archive  Online Backup:  number of backups stored in full backup  number of incremental backups / diff / full stored in the backup  frequency of transaction log backups stored in the backup (for databases)  number of days the backups to be stored on-line backup system  The list of nodes defined in the system backup:  Domain | Node name | IP address of the node  The list of defined backup tasks (called schedule)  name of the task (schedule) | execution time  a period of at which the task is repeated
  12. 12. BEST PRACTICES BY BRENT OZAR SQL Server Backup Best Practices | Written on October 17, 2007 by Brent Ozar in SQL Server >> http://www.brentozar.com/archive/2007/10/backing-up-sql-server-my-own- mediocre-practices/ I’ve been backing up SQL Servers for almost a decade now, and it’s time to share the lessons I’ve learned. All of this is my own opinion – your mileage may vary – but I’ll try to explain the reasoning behind the choices I make. I won’t address log shipping or snapshots this time around. • Never back up databases to local disk. • Back up databases to a fileshare, then back the share up to tape. • Cost justify the network share with lower licensing costs & simpler backups. • Back up to a different SAN if possible. • My sweet spot for the backup array is raid 10 SATA. • Backup agents like NetBackup and Backup Exec mean giving up scheduling control. • Do regular fire drill rebuilds and restores. • Build a standalone restore testbed. • Keep management informed on restore time estimates. • Trust no one.
  13. 13. BEST PRACTICE FOR SURVIVING DISASTER ITS ONLY ONE: BE PREPARED Restore  about type of backup ( simple rm / full rm)  about place for stored backup data  about the procedures of recovery  about estimated time for recovery  about REAL TIME for recovery  about tools for recovery  about Corporate Backup Manager  about password for access to library
  14. 14. RESTORE > extract from SOP* Register for Recovery/Restore/Replacement Tests This register contains information about the tests and replacement of part or all of the environment. It consists of the following fields:  the date of commencement and completion of the recovery test  client for which the test was performed recovery test  servers involved in testing and replacement  extent of testing and replacement  person / persons performing the recovery test  person on the client side accepts the correctness of the recovery test  subsequent to the recovery test
  15. 15. BEST PRACTICE FOR SURVIVING DISASTER ITS ONLY ONE: BE PREPARED Procedures  It is not about stored procedures!!!  It’s about storing procedures with answers for the following:  One piece of paper  How to start restore  Who can help  How to processing a restore  When we can finish  It MUST be simple
  16. 16. BEST PRACTICE FOR SURVIVING DISASTER ITS ONLY ONE: BE PREPARED Roles  Database Administrator  Windows Administrator  Backup Administrator  Network Administrator  Customer Key Account  Manager of division  Data Center Manager  Nightshift Operator - BOFH  Customer Administrator!!
  17. 17. BEST PRACTICE FOR SURVIVING DISASTER ITS ONLY ONE: BE PREPARED PSO > USO > SLA  PSO Planned System Outages – Planned System Unavailability  Minimum planned unavailability, due to the need to carry out modernization work, installing patches, replacement / extension of hardware,  Agreed/accepted by/with the client and not affecting the provisions of the HA, and SLA, until  ...USO Unplaned System Outages – Unplanned System Unavailability  an error that prevents a partial or total work environment in a tangible, measurable customer  resulting in high costs if you need repairs, as well as penalty payments for non-SLA
